 ThumbsPlus Release Notes 3.30

Contents Copyright ©1996-1998, Cerious Software, Inc. All Rights Reserved.

Here are some of the benefits of registering ThumbsPlus:

•	View Zip files as folders. You can see directly inside ZIP files to view, print, thumbnail and find your images.

•	Additional file types. Adobe Type 1 fonts, DXF, Kodak Pro DCS and MPEG files.

•	TWAIN scanning. Acquire images directly from scanners, digital cameras, and other TWAIN-compliant input sources. You can even acquire multiple scans directly to files without having to "save" each one.

•	No more nagging. No more automatic "splash" and order screens to remind you that your legal use of ThumbsPlus has expired.

•	ThumbsPlus Database Utilities. These utilities provide the abilities to repair and compact ThumbsPlus databases.

New File Types Supported	3.30

.CEX	Multiple-image JPEG files distributed by Walmart and Fujifilm. These files are handled as multi-page files within ThumbsPlus. You can also split them into individual files. Note: I only have a few samples of CEX files. If you have any that do not work, please send them to us or upload to our FTP site.
.PIC	BioRad Confocal PIC files
.PIC	SoftImage PIC files
.FPX	Kodak FlashPix. This is a read-only implementation. (FlashPix was designed as a whole philosophy of image storage and processing that clashes with the support for dozens of formats and the methods of image processing in ThumbsPlus. I have provided FlashPix Support in ThumbsPlus mainly for compatibility with digital cameras that produce FPX files. Write capability will likely be added in a future release; however, support for storing and modifying the image transforms is unlikely.) ThumbsPlus reads the transformed image data; rotations and adjustments stored in the FPX file are applied. If you want to read the original image instead, add the following to the THUMBS.INI file: [FlashPix] NoTransform=1


File Support Improvements	3.30

•	ThumbsPlus will now read digital camera (APP12) markers in JPEG files and display the information in the image comments.

•	Several problems with ATM font recognition and loading were fixed.

•	Fixed a problem with some unusual SFW files.

•	Fixed a problem reading grayscale DCS files.

•	Fixed a problem in GIF animation painting.


Miscellaneous New Features	3.30

•	When assigning keywords from the View window, the keyword dialog is positioned to the side or below the view window if possible.

•	ThumbsPlus will no longer allow a JPEG quality less than 20, and performs some additional checks when using the original quality.

•	ThumbsPlus now retains the original case of the extension when generating file names, such as during Batch Processing. (For example, conversion from ABC.BMP will result in ABC.JPG rather than ABC.jpg).

•	In all places where ThumbsPlus accepts a file mask (Edit|Select by Mask, Options|Preferences|File List, Options|Which Files|By Mask), ThumbsPlus will accept multiple masks separated by a semi-colon; for example: "*.jpg;*.gif;*.bmp."

•	The menu item for toggling between showing Selected Types and By Mask has been split into separate items for clarity. Additionally, selecting "By Mask" now allows you to enter a new file mask without having to open the File List preferences.


Problems Fixed	3.30

•	Fixed a resource leak when thumbnailing or viewing icon (.ICO) files.

•	Eliminated a memory leak when thumbnailing or viewing raster PICT files.

•	Autocrop did not work properly with bi-level (monochrome) bitmaps.

•	Fixed a paint problem with the selection rectangle in the view window.

•	Print Catalog no longer prints a blank page if the last page is completely full.

•	Made the file recognition routines less likely to incorrectly identify a MacPaint file.

•	The maximum values for number of columns is adjusted properly in Print Catalog and Contact Sheets.

•	A problem writing TIFF 48-bit palettes was corrected.

•	ThumbsPlus now zeroes the buffer for reading TIFF data, which works around problems reading some files that were stored with incomplete strips (especially some invalid CCITT group IV files.)

•	The "Category" drop-down in New Filter and Edit Filter is now properly filled in.


Miscellaneous New Features	3.21

•	You may now select for animated GIF files to loop in Options | File Loading | GIF. Only one GIF animation may be active at a time.

•	CMYK TIFF files with alpha channels are now loaded properly.

•	Support has been added for BioRad Confocal .PIC files.

•	Support has been added for Olympus Confocal .TIFF files

•	FLC files will now automatically thumbnail from the first frame.

•	New versions of DCS (Kodak Professional Camera) files are now supported.


Problems Fixed	3.20

•	Fixed a filename display problem on Win32s (the filenames displayed with path information).

•	L*a*b color space conversion in TIFF and PSD files is now much more accurate.

•	Support provided for BMP files with BI_BITFIELDS and more than 8 bits per pixel.

•	"Customize toolbar" now remembers "office 97 style" toolbar setting.

•	Options | File Loading | PhotoCD now saves your selected PhotoCD resolution and format so you don't have to reset each time you start ThumbsPlus.

•	When saving a GIF file, the GIF type (87a,89a) option was not set appropriately.

•	ThumbsPlus will now read JPEG files with invalid COM marker lengths (i.e., some Accusoft-generated files).

•	The Equalize Histogram command was not available from Batch Conversion.

•	Slide show (-s) and some DDE commands didn't change to the indicated directory.

•	ThumbsPlus now shows any defined alias when asking you to insert an offline volume.

•	The File | Open Database and File | New Database commands now default to current database's location.

•	The Web Page Wizard shortcut key has changed to Ctrl+Shift+F8 (the previous shortcut key conflicted with multi-file keyboard select).

•	ThumbsPlus no longer needlessly builds a palette when batch converting images to Truecolor (RGB) mode.

•	Some WPG files that reported "out of memory" because of extremely complex Bézier curves now render properly.

•	In a view window, the Next File and Previous File options were disabled after reloading a file.

•	Import filter names were not evident because of long paths (now shows name at start, followed by the full path).

•	ThumbsPlus now forces a space between the font sample text and the font name

•	Combine keywords (Options | Database | Edit Keywords) didn't work unless you entered one of the selected keywords.

•	The slide show became the "slide slow" after a while, and would sometimes consume unnecessary system resources.

•	I changed the background color for histogram. ThumbsPlus now uses the Tool Tip color from Control Panel, unless it is a shade of gray, in which case blue is used as the default.

•	"Match by share name" now disables matching network volumes by serial number.

•	The view window scroll bars are now proportional to the size of the viewable portion of the image (Windows 95/NT 4 only).

•	Fixed problem where thumbnails did not always move when moving files (overwrite). Any old thumbnail is now properly overwritten when the file is overwritten.

•	Movies (AVI, MOV, MPG, etc.) now appear in the Slide Show, and on Windows 3.1/Win32s.

•	Other minor fixes.


New File Types Supported	3.20

.IPL	IPLab images. Image files generated by versions 2 and 3 of IPLab. ThumbsPlus supports 8-bit grayscale, 16-bit grayscale, 32-bit grayscale, and 32-bit color images. Multi-frame files are also supported. 16 and 32-bit graycale images are scaled to 8-bit when loading.
.FIT, .FITS, .FTS, .LBL, .HDR	NASA FITS images. ThumbsPlus supports many variations of FITS images, including various record formats (VAX, CRLF, fixed).
.PBM, .PGM, .PPM, .PNM	Portable bitmap, graymap, pixelmap and anymap (popular Unix intermediate formats for converting between file types using the PBMPLUS and NETPBM utilities).
.PDS	NASA Planetary Data System files
.IMQ	Compressed PDS files (NASA)
.255	A variant SBIG format (similar to .ST5). Compressed and uncompressed images are supported.
.FLC, .FLI	Autodesk Animator animation files (Windows 95 only).
.AU, .SND, .AIF, .AIFF, .AIFC	These sound file formats are now supported, as long as Microsoft ActiveMovie is installed on your system.


Miscellaneous New Features	3.20

•	Picture | Find by filename - to search the ThumbsPlus database for specific file names or masks.

•	By checking the "Auto view" box in Image | Color Adjust and View | Assumed Gamma, you can now automatically view color adjustments as they are being made. (Not recommended for slow displays!)

•	You can now pan view windows (by dragging with the right mouse button, or CTRL+left button).

•	I added an image processing option (Image | Process | JPEG Cleanup), which smoothes the edges of JPEG DCT blocks. It won't recover losses from JPEGs compressed too far, but often makes them prettier.

•	The most recently assigned keywords (single or multiple) are available for quick assignment when using the right-click context menu to assign keywords in the main window.

•	On startup, ThumbsPlus checks for unlabeled hard drives and gives you the opportunity to label them.

•	The slide show now (again) defaults to all files if only one is selected. I'll make this an option if enough people request a "single-file slide show."

•	Database import and export, for combining or splitting databases, and for transferring database information to other programs.

•	Improved external filter support. Many more Aldus filters work properly, including the ones distributed with Microsoft Office products.

•	ThumbsPlus now properly orients TIFF files with unusual orientations.

•	You can now specify planar-organized raw RGB/BGR files (Options | File Loading | Raw).

•	ThumbsPlus now uses horizontal differencing (for improved compression) with LZW saves of 24-bit TIFF files.

•	ThumbsPlus shows memory requirement for loading image in Info box, and size of image in the view window status line.

•	The preview in the Color Adjust dialog is a wee bit larger.

•	The file resolution (dpi) for JPEG files now appears in File | Properties.

•	The File context menu now includes the Print command.

•	New splash screen.

•	Histogram stretch (contrast stretch) now available from Histogram and Batch Convert/Edit.

•	The help file has been enhanced and updated (there's still more to do, but it's more up-to-date than it was).


Problems Fixed	3.10

Note: ThumbsPlus version 3.10 does not represent major changes since version 3.0g; instead, it re-aligns our version numbers and indicates the enormous amount of development that has occurred since the original version 3.0.

•	Using some display drivers, 8-bit RLE BMP files would not load with the correct colors.

•	Loading a CAM file showed the progress indicator and brought the ThumbsPlus main window to front.

•	Reducing to 8-bit color is more accurate and faster in some cases.

•	The "disappearing toolbar" magic trick is gone (where the toolbar would occasionally display blank).

•	The volume information and disk drive letter are properly displayed on Windows 3.1/Win32s.

•	A default toolbar can now be stored in the THUMBS.DEF file for network installations.

•	I fixed problems with multiple keyword lookup dialogs and the "found" list disappearing when pressing <ESC> in a view window.

•	"Save As" would not work properly on Windows NT 3.51.

•	View window accelerator keys work in slide show again.

•	Fonts were sporadically installed during catalog/contact sheets.

•	AVI files in the same folder caused catalog, contact, and web page problems.

•	An IPF occurred in DIBENG when auto-cropping some metafiles.

•	Pasting a screen capture did not work properly on Windows NT 4.0 with some 16 or 32-bit display drivers.

•	The monitor gamma was ignored in the color adjust preview and view.

•	The annotation and keywords would not always print when printing images.

•	Fixed a problem communicating with some incorrect TWAIN data sources.

•	Invalid compressed BMP files that would crash some display drivers.

•	Some invalid KDC files would cause a GPF or IPF.

•	The result of cropping a monochrome (bi-level) bitmap would often be off by several pixels.

•	The Remove Orphan options "Current Drive" and "All Local Drives" are now operative.

•	"Best fit for sizing" now properly selects "Resample" when reducing and "Bi-cubic" when expanding an image without rotation.

•	Bad or malformed ICO files could cause ThumbsPlus crashes, especially on NT.


Miscellaneous New Features	3.10

Note: ThumbsPlus version 3.10 does not represent major changes since version 3.0g; instead, it re-aligns our version numbers and indicates the enormous amount of development that has occurred since the original version 3.0.

•	A "Multi-page" keyword is now automatically assigned for animated GIFs, multi-page TIFs and DCX files, if Automatically generate keywords … From image attributes is checked in Options | Preferences | Keywords.

•	Minolta RD-175 (.MDC) camera files can now be read and thumbnailed by ThumbsPlus.

•	ThumbsPlus can now thumbnail and view Adobe Type 1 (ATM) fonts (.PFB files) on Windows NT if  ATM deluxe 4.0 NT is installed.

•	You can sort the file list by numeric file name. This will correctly sort file names such as "abc1.jpg," "abc10.jpg," and "abc2.jpg."

•	I moved the file name displayed in the slide show to the bottom-left corner of the screen, as it is more likely to be visible there.

•	The dates and times DC40, DC50 and DC120 images were taken are now included in the comments and details for KDC files.

•	Web Wizard thumbnail files (tn_*) now include the original file extension to avoid duplicate thumbnail file names when multiple originals had the same name but different extensions.

•	I added a "Save and Close" option to the View Window. This will save the file and close the window using one command.

•	A new DDE command, ExportThumb is available. This command will extract all selected files' thumbnails as images and save them to files. Its syntax is:

ExportThumb(type;extension;path)

Where type represents the file type to write, extension represents the file extension to use, and path provides the output path for the thumbnail files.

•	ThumbsPlus now recognizes GIF files that contain garbage before the GIF header (such as files saved by Microsoft's proxy server), and GIF files with zero sizes in the screen header.

•	Autocrop now ignores images that are entirely one color. This produces more visible thumbnails for solid files (rather than only a vertical line).

•	I added a "Save" button to the Edit Comments window so you can save image comments to a text file.

•	Uncompressed TIFF files with invalid strip lengths can now be read.

•	You can now acquire and save to multiple files without viewing first (especially useful for auto-document feeders). The menu option Picture | TWAIN Multiple Acquire produces a dialog box where you specify the prefix, sequence number, and file format for the stored scans. To help you keep things in sync, ThumbsPlus uses the same prefix and sequence number for single acquisitions.

•	ThumbsPlus can save TIFF files with reduced color information (6 bits red, 6 bits blue, and 7 bits green) for increased compressibility. To enable this option, select Skim low-order bits from the Tiff Options dialog while saving. This option is only useful for saving 24-bit images; for other image color depths, it is ignored.


Problems Fixed	3.0g1

•	Selecting the "Include Lo-res" option in the Web Page Wizard caused ThumbsPlus to crash.

•	ThumbsPlus did not position to the start-up directory when a new database was opened.

•	The font selected for displaying image comments was not saved.

•	EPS files would sometimes be left open (and unable to delete) after thumbnailing or viewing.

•	Images and metafiles were always cropped on catalogs and contact sheets, without regard to the option setting.

•	The third view window cursor (Options | Preferences | Viewing) did not work properly.

•	24-bit RGB Raw images were not decoded properly.

•	Metafiles are now copied to the clipboard to be compatible with Office 97 applications, which do not follow Microsoft's own guidelines for pasting metafiles! This should also work around problems with other programs that were not pasting metafiles correctly.

•	Anti-aliasing is faster and more accurate when converting metafiles to bitmaps, and when making thumbnails of metafiles.

•	Attempting to combine or rename keywords of exactly 32 characters would cause ThumbsPlus to crash.

•	ThumbsPlus would sometimes crash in the Rotate/Resize dialog, especially when fitting to height or width and entering numbers directly.

•	.MND (Mandelbrot) files could not be loaded.

•	The Professional DCS camera library (PDC_API.DLL) was not distributed in the 3.0g Registered Upgrade.

•	Options | Which Files | Child Folders now works properly for offline volumes.

•	I fixed several other small bugs.


Miscellaneous New Features	3.0g1

•	You can now specify up to five keywords for the keyword lookup (Picture | Find), and the keyword search is somewhat faster.

•	The .PMP file type (Sony digital camera) is now supported.

•	There's an "Office 97 style" option for the toolbar (Window | Customize Toolbar), and the small toolbar buttons are sharper.

•	ThumbsPlus will refuse to delete the Windows or System folders, and EXE, DLL, SYS and DRV files incur an additional warning while deleting.

•	You can turn on the option for viewing thumbnails for the entire current tree (child folders) by default from Options | Preferences | File List. Note that this can be rather slow, especially for drives with many files or directories.

•	A few new THUMBS.INI file options are available:

[KDC] UseThumbnails	Set to one (1) to cause ThumbsPlus to use the thumbnail present in some KDC files.
[Catalog] AlwaysCenter	Set to one (1) for ThumbsPlus to always center the columns. (The default is to left-justify when annotations or keywords are selected.)
[ContactSheets] AlwaysCenter	Set to one (1) for ThumbsPlus to always center the columns. (The default is to left-justify when annotations or keywords are selected.)
[Startup] NetworkAsRemovable	Set to zero (0) for ThumbsPlus to treat network drives more like local disks (each drive will be queried for its label or connection info upon startup).
[Startup] NoExpand	Set to one (1) for ThumbsPlus to open with all drives collapsed.


New File Types Supported	3.0g

The following file types are now supported by ThumbsPlus:

KDC	Kodak DC120 native camera format. I believe that DC25 images are also supported, but do not have any examples for verifying this. ThumbsPlus also loads the image information for all KDC files (exposure time, zoom focal length, f-stop, distance from camera, etc.) into the image comments, and displays them in Picture | Properties | Details.
SGI, RGB	Silicon Graphics Image files. These are the native raster files from Silicon Graphics workstations.
SFW	Seattle FilmWorks (Mangled JPEG files). SFW files are standard JFIF files with different codes for the markers and DCT tables removed.
DCS (registered only)	Kodak Professional Digital Camera TIFF files. Images produced by the DCS4xx series of Kodak cameras are now supported. They have the standard TIF extension, but are not really TIFF files. Unfortunately, the DCS library requires that the extension be TIF to load them, so don't rename them!
MIC	Microsoft Image Composer files. ThumbsPlus loads these files as a single image (all layers are combined).


File Support Improvements	3.0g

TIFF	16-bit grayscale TIFF files are now auto-scaled to 8 bits when loading (rather than simply using the high-order 8 bits). This behavior can be reverted to the original behavior by adding a line "AutoScale16=0" to the [Tiff] section of THUMBS.INI
PNG	PNG files may now be saved. Transparency and interlacing are not yet supported.
JPEG	Saving JPEG files as grayscale is no longer available. As far as I could tell, this option only caused problems. To save a JPEG image as grayscale, just use Image|Color Depth to reduce it to grayscale before saving.
JPEG	The original JPEG image quality is now computed from the quantization tables and used by default for re-saving JPEG files.


Web Page Wizard	3.0g

The Web Page Wizard, available on the Thumbnail menu, provides a way for ThumbsPlus to generate web pages of thumbnails for publishing on the World Wide Web.

The wizard will guide you through the steps required to make an on-line catalog of images, and several templates are available for different web page appearances. The catalog can be a single page, or may span several pages.

If you select more graphics than will fit in the table, ThumbsPlus will automatically generate multiple pages; each generated page will have link to the next and previous pages.

Details on the Web Page Wizard are available in the Online Help.


DDE Commands	3.0g

ThumbsPlus responds to many additional DDE commands, including: Close, CopyClipboard, Exit, Find, Keyword, LocateFile, MakeThumb, Open, OpenDB, OpenDir, Print, RefreshTree, Remove, RemoveTree, ScanTree, SlideShow, UpdateAll.

Full details are available in the Online Help.


Toolbar Extension	3.0g

This release of ThumbsPlus allows you to add toolbar buttons that correspond to other applications. When pressed, these buttons cause the application to execute and open any selected file(s).

In order to provide this capability, the Customize Toolbar dialog has a new button, labeled "External Program." When clicked, another dialog displays, giving you the opportunity to locate and configure an external program.

Further details are available in the Online Help.


Printing and Catalog Enhancements	3.0g

•	When printing images, you can now select whether to print them at the resolution (DPI) stored in the image.

•	You can now include various textual items with printed graphics (Picture | Page Setup), including: Name, Size, Date/Time, Dimensions, Resolution, Keywords, Annotation, and IPTC/NAA information.

•	When printing a catalog or making contact sheets, you can now include the keywords and annotation.


New Image Processing and Viewing Functions	3.0g

•	Image filters are now directly accessible from the Filters sub-menu of the Image menu in a view window. When filters with options (i.e., direction, channels or aperture) are picked this way, the last settings are used. To bring up the settings dialog box, press SHIFT when selecting the menu item.

•	ThumbsPlus can now generate a common optimized palette from multiple images. You can create such a palette by itself (Edit | Common Palette), or when batch processing a group of images (select "Common Optimized" from the Palette drop-down in Picture | Batch Convert/Edit | Color Depth).

•	Resample is available as an interpolation method when resizing images. This is best for reducing the size of images.

•	Bi-level images may be scaled-to-gray when reduced for display (Options | Preferences | Viewing).

•	ThumbsPlus can dither output to 15 or 16-bit displays (Highcolor) for improved appearance. You can turn this on in Options | Preferences | Viewing.

•	There are several image processes available from the Image menu in the view window:

Auto Color Balance Shift+A	Attempts to color balance the image, based on an average of all pixels or an average of the pixels in the current selection. If you make a selection, select an area that should appear gray rather than colored.
Improve Video Capture Shift+V	Increases the image saturation and contrast, and lightly sharpens the image.
Fluorescent Lighting Shift+L	Attempts to eliminate the color shift caused by fluorescent lighting. Since different cameras and videos have different responses to the shift, and because different lights have different effects, this filter only handles some cases.
General Enhancement Shift+G	Increases image saturation and contrast, and sharpens the image.
Contrast Enhancement Shift+C	Increases image contrast and adjusts assumed gamma by 20%.


Miscellaneous New Features	3.0g

•	You can set the minimum time between automatic directory updates (the default is 5 seconds) in the Thumbs.ini file. Add the entry "DirectoryScanFreq=5000" to the [Startup] section. The value is the number of milliseconds between refreshes.

•	You can now assign multiple keywords to selected file(s) by separating them with semi-colons in the Assign Keyword dialog box.

•	ThumbsPlus now identifies files faster if their extension matches the file type (i.e., it checks if a file named "xyz.jpg" is a JPEG before attempting to identify it as any other type).

•	On Windows NT and Windows 95, the default "Save As" dialog box is now the new Explorer style.

•	Several file types have been added as shown by default.

•	You can map and disconnect network drives from within ThumbsPlus.

•	Thumbnail|Scan System is now available. This provides you the opportunity to scan all drives (or categories of drives) in one fell swoop.

•	You can save the list of errors generated to a file.

•	The font window saves and uses the last size and position.

•	The file list builds and updates somewhat more quickly. For the fastest updates in directories with lots of images, you should set these options:

Options|Preferences|General - Show Orphaned Thumbnails is OFF.

Options|Preferences|General - Automatically Remove Orphans is OFF.

Options|Preferences|File List - Order by is Unsorted. By Name or by Extension are the next fastest.

•	You can now do a slide show for the files in the current folder and all its sub-folders (recursive).

•	You can specify, in each TDO file, whether hidden and system folders are shown in the directory tree:

[Tree]
ShowHiddenDirs=1	The default is to show these directories (i.e., MS Internet cache)
ShowSystemDirs=1	The default is to show these folders (i.e., Windows\Fonts)
ShowHiddenSystemDirs=0	The default is to not show these folders (i.e., Recycled)
•	Prettier icons (at least I think so).

•	There are several menu items which can be modified by pressing ALT or SHIFT when selecting them:

Picture|Slide Show	Press ALT or SHIFT to bring up the Slide Show Options before running the slide show.
Image|Filter	Press SHIFT to bring up the Filter Options dialog for the specific filter selected.
Options|Sort By|…	Press SHIFT to toggle ascending/descending when picking a new sort order.
•	You can now select that all thumbnails in sub-folders be included in the current file list (thumbnail view). The menu option is Options|Which Files|Child Folders.

•	You can toggle between selected file types and a file mask using Options|Which Files|All Files.

•	The startup options have been removed from Options|Save for Startup, and are now available in Options|Preferences|Startup. This makes saving current window size, tree, and directory much more convenient.

•	An "Autocrop after Resize" button has been added to the Rotate/Resize dialog.

•	If multiple users desire different profiles (INI and TDO information) on the same Windows 95 or NT system, you can define these keys in the Registry for each user:

HKEY_CURRENT_USER\Software\Cerious Software Inc.\ThumbsPlus\IniFile

Enter either a simple file name (i.e., "John_Thumbs.ini"), or a complete path to a file name.

HKEY_CURRENT_USER\Software\Cerious Software Inc.\ThumbsPlus\TdoSuffix

Enter a suffix to append to the TDO file name for each user (i.e., "_John")

Do not put quotes around either string!


Problems Fixed	3.0g

•	Creating contact sheets or batch converting a group of files that includes sounds, cursors, or fonts no longer causes an IPF.

•	Invalid or partial ZIP files no longer cause spurious message boxes when scanning a drive or tree.

•	View while Loading is no longer available for PhotoCD files (it didn't work correctly anyway).

•	A memory leak was fixed when loading PhotoCD files, and they are loaded considerably faster.

•	When Gamma Correction is set, View While Loading is on, and JPEG's were loaded in 8-bit mode, the colors were wrong until the view window was resized or modified.

•	Page Setup now correctly displays all margins correctly (the top margin was being substituted for all margins before).

•	Incorrect free disk space values were reported when more than 2GB were free on a drive.

•	Blank headers & footers in contact sheets and catalogs are now properly saved to the INI file, and blank lines are no longer added.

•	The "New page for each directory" option now works correctly for both contact sheets and catalogs.

•	The selection rectangle is now easier to see and behaves more properly.

•	Write errors in TIFF files are now only supported once.

•	Edit|Select All (Ctrl+A) did not work properly when only a single file was in a folder.

•	The "screen background" is eliminated by default from when saving GIFs.

•	Options|Viewing|Zoom-Fit to Width did not work properly.

•	Zip files on CD-ROMs did not work.

•	CD-ROMs and removable volumes without volume labels would not show up in the folder list.

•	Orphan thumbnails no longer disappear when the file list refreshes because of a change in the folder.

•	Folders are colored properly when files are moved or copied into them.

•	ThumbsPlus responds more appropriately when you change the display color depth on the fly.

•	Adobe Type Manager font names now appear in the file list, rather than the file names.

•	Multi-page DCX images are now handled properly, and the DCX file type has been added to the file type list.

•	The file list is more appropriately positioned after deleting or moving a bunch of files.

•	Many fixes to printing catalogs and making contact sheets.

•	Fonts with 8-bit characters in the font name are now properly thumbnailed.

•	When the TWAIN update is selected during installation or upgrade, ThumbsPlus now properly forces all TWAIN DLLs and EXEs to the Windows directory.

•	You can now enter both a width and height in Rotate/Resize for batch conversion.

•	Several other small bugs were fixed.


Problems Fixed	3.0f2

•	A Win32s problem caused ThumbsPlus to repeatedly update the file list on Windows 3.x.

•	To fix the problem where the mouse could not sometimes be used in confirmation dialog boxes, ThumbsPlus no longer updates the file list when a dialog box is shown.

•	256-color icons are now shown and thumbnailed properly.

•	The recycle bin, automatic removal of thumbnails, and aspect fit in the slide show are now on by default after installing ThumbsPlus.

•	An "Unsorted" option was added to Options | Sort By.

•	When multiple drive letters are mapped to the same network disk, drive entries no longer disappear when switching between them.

•	File library warnings (which do not affect the loading of files) are now off by default. You can enable them using Options | Preferences | Advanced.

•	Options | Preferences | File List now includes an option to disable automatic detection of directory changes. (Window | Refresh or F3 can still be used to update the list manually.)

•	ALT+Enter is now another keyboard shortcut for Picture | Properties.

•	The pixel position and color were not reported correctly in the View Window status line. (The pixel below and to the right of the current pixel was shown instead.)

•	Volume | Properties (from the context menu) now shows additional information about both the physical volume and how it is matched in the database.

•	ThumbsPlus now loads as much as possible of incomplete TIFF files ("Read Error on strip…").

•	Images are now only auto-cropped when printing if "Autocrop when Viewing" is on in Options | Preferences | General. (In a future release, printing will receive its own option setting).

•	The keyword drop-down lists can now be turned off (Options | Preferences | Keywords) to improve performance when thousands of keywords are in use, or for when the database is on a network.

•	The error messages generated by the ThumbsPlus Database Utilities are now more meaningful.

•	Black pixels in PiNG files were sometimes rendered as transparent.


Problems Fixed	3.0f1

Installation issues:

•	Registry utilities combined into a single utility (which now works).

•	Removed file type registration from initial install, as the method used was not 'undoable' by the Registry Utility.  Use the Registry Utility instead. The registry utility is installed with the registered version.

•	3.0f installed a CSWOLE.DLL library that required different Microsoft DLLs than were installed by the program. This broke OLE access on many systems.

•	Registered installations and upgrades no longer completely overwrite the THUMBS.TYP (file type definitions) and THUMBS.FLT (image filter definitions). However, pre-defined types and filters are replaced with the defaults

•	The registered upgrade properly copies all files from the System sub-directory to the installation directory (the new NETUSER does not use the system directory).

File support issues:

•	QV-100 CAM files were not handled properly.

•	KDC files created by newer versions of Kodak's software were displayed as TIFF files (thumbnail only).

•	Tiff files converted from JPEGs that had IPTC or Photoshop information were not readable.

•	Invalid GIF tags are now ignored, instead of causing the load to fail.

•	Fixed a text alignment problem in CGM files.

•	Fixed some raster WPG (version 2) problems, and a problem which occasionally caused Invalid Page Faults or GPFs when loading WPG files.

•	Added some built-in raw types (CT scan, MRI, SBIG ST4, and Mammogram).

•	RAW files are now recognized with any extension (as long as they're in file list).

•	ThumbsPlus always warned that fonts being removed were in the system's Fonts directory, even when they weren't.

View Window issues:

•	Improved viewing speed (while fixing a couple of problems).

•	Fixed "View while loading" for files stored upside down (bottom-to-top), including some TIFF and CPT files.

•	Windows no longer grow past edges of screen when zooming in

•	Improved gridline appearance when zoomed.

•	You can now set "Bitmap Window Size" in Options | Preferences | Advanced to zero; this disables any use of intermediate bitmaps when displaying.

•	ThumbsPlus is now more attentive to desktop area (task bars, etc.), and will not open a window occluded by them.

•	Eliminated the unnecessary horizontal scroll bar when an image is only taller than screen (but not wider).

•	Fixed problem thumbnailing metafiles from view window

•	Fixed keystrokes (and added a couple of sizes) in the Rotate/Resize dialog box (Image | Rotate/Resize).

•	In Image | Rotate/Resize, Aspect fit to "Both" now re-computes width or height when other is changed.

•	Fixed a problem which caused a GPF or IPF when trying to adjust or rotate an unusually long or tall image.

User Interface issues:

•	Fixed keyboard context menus (Alt+F10 or "context" key).

•	Fixed some menu accelerator keys that were shown incorrectly in the menus.

•	The "Close" button in the progress dialog now receives focus after processing so that a Space or Enter keystroke will dismiss it.

•	File name mask (Options | Preferences | File List) now properly handles files without extensions.

•	Fixed a thumbnail cache problem (the wrong thumbnail displayed when old name used for new file).

Miscellaneous Issues:

•	Catalogs did not print properly when "Rebuild at Printer Resolution" was not selected.

•	Resource leak when thumbnailing/transforming metafiles with text.

•	Improved font thumbnailing speed and appearance for some font names.

•	Eliminated some spurious "Unable to install font" errors.

•	Fixed resource leak (cursor) when processing lots of ZIP files.

•	16-bit TWAIN data sources now work in the registered release, which includes the latest TWAIN libraries from the TWAIN Working Group.


New File Types Supported	3.0f

These file types have been added in version 3.0f:

KDC	Kodak DC40/DC50 native camera format
CAM	Casio QV series native camera format
KQP	Konica native camera format
MAC	Macintosh Paint format
PCT	Macintosh PICT format


File Support Enhancements	3.0f

IFF	HAM6, HAM8 and masked files are now properly supported.
PCD	You may now choose the resolution on the fly when displaying PCD files: CTRL: Load at 1536 x 1024 ALT: Load at 384 x 256 CTRL+ALT: Load at 768 x 512 (base)
BMP	Upside-down (negative height) BMP files are supported
PFB	Adobe Type 1 font support improvements, including support for Multiple Master typefaces & instances.


Metafile Processing Enhancements3.0f
hlpMetafile Processing Enhancements	3.0f

ThumbsPlus now has many additional processing functions for metafiles:

•	Metafiles may be rotated (using Image | Rotate & Resize).

•	Metafile colors may be adjusted (using Image | Color Adjust).

•	Metafiles may be auto-cropped.

•	The first bitmap may be extracted from a metafile (Image | Extract Bitmap). This is especially useful when pasting gets a metafile that is only a bitmap.

•	Metafile rasterization (conversion to bitmap) can now be anti-aliased, reducing "jaggies" and improving the appearance of the bitmap. (Image | Convert to Bitmap).

•	You can remove background objects (i.e., rectangles that fill the view area) from metafiles (Image | Remove Background).

•	You can specify the background color that ThumbsPlus uses when displaying metafiles (Options | Preferences | Viewing).


ThumbsPlus Registry Utilities	3.0f

The ThumbsPlus Registry Utilities, used to associate and disassociate file types with ThumbsPlus, are now included in the registered distribution. For the shareware release, you can download them from our Web site, http://www.cerious.com.

These utilities provide a quick way to associate specific file types with ThumbsPlus. Additionally, the registration utility (TPREG) saves old associations, so if you later disassociate the files using TPUNREG, the previous associations are restored.

Shortcuts for both TPREG and TPUNREG are installed on the Start Menu or in Program Manager. Using the utilities is simple - run them and follow the instructions.


Miscellaneous New Features	3.0f

•	IPTC/NAA information from JPEG and TIFF files is now shown in the Picture | Properties display.

•	IPTC/NAA keywords may now be automatically assigned in the ThumbsPlus database when they are present in JPEG and TIFF files.

•	A new and simpler Rotate/Resize dialog, with additional options (bi-cubic interpolation, background color, and more preset sizes).

•	Edit | Set Resolution is available in the view window to set the resolution (DPI, DPC) of an image; this is useful when importing files into word processing and page layout applications.

•	You may now assign keywords based on the complete file name, as well as on the words in the file name (which was the previous behavior).

•	The Color Depth dialog now supports additional palettes:

Windows 16 Standard:	This is the "standard" Windows 16 color palette

Windows 16 Light:	This is another Windows 16 color palette, implemented by some display drivers.

•	The Color Depth dialog now supports additional dithering modes:

Noise Level:	Select to add noise to the image when dithering; sometimes improves results.

Ordered:	You may select an ordered dither (order 1 to 8) when converting to bi-level.

Jarvis, Judice, Ninke:	An additional error-dispersal dithering algorithm.

•	In the View Window, the TAB and Shift+TAB keys now switch to the next or previous open view window.

•	Several new colored view window cursors were added.

•	A single keystroke (ESC) now closes a full-screen image, rather than restoring the window to normal size. To restore to normal size, you can still use F3.

•	Added Thumbnail Background color to Options | Preferences | Colors. This controls the color of the unused background area within the thumbnail boxes in the file list.

•	When using network drives, you can now specify (Options | Preferences | General) that ThumbsPlus match them with the database them on the share name (rather than just the volume label). This is useful if multiple shares are mapped to the same logical drive.

•	ThumbsPlus handles read-only database (i.e., shared on a network as read-only) much more nicely, and will automatically open a database read-only if it cannot open it shared.

•	The installation has been rewritten with additional options.


Problems Fixed	3.0f

•	Fixed a problem with not invalidating cache when opening new database (sometimes thumbnails from the old database would appear in the window after opening another).

•	Fixed the blank line in file list when name not selected.

•	Fixed file list display when thumbnail not shown; the items are now tabbed appropriately.

•	Fixed Photoshop problem loading multi-channel palette and duotone files.

•	Picture | Wallpaper | Stretch now works on all platforms.

•	Keyboard focus now stays with the file list (thumbnail display) unless specifically changed with the TAB key.

•	Several other small fixes.


Shareware Enhancements	3.0e

The following functions, previously available only in the registered version, are now available in the shareware as well:

•	Linear, statistical and morphological digital image filters. Most filters operate either on intensity or all channels; some can be applied to specific color channels as well. The filters include:

Sharpening (sharpen, sharpen less, sharpen more, directional sharpen, unsharp mask),

Blurring (blur, blur more, average, Gaussian 7x7, Bartlett 7x7),

Edge detection (strong, weak, Laplacian, Laplacian inverted, Prewitt, Sobel, morphological gradient),

Noise removal (despeckle light, despeckle dark, maximum, minimum, median, add noise),

Special effects (emboss dark, emboss light, etch, outline dark, outline light).

You can also define your own linear filters, up to 7 x 7.

•	Image histograms, including histogram equalization.

•	Both the filters and image histograms operate on single images, or on multiple images (batch mode).


File Support Improvements	3.0e

CGM support is improved:

•	Extent defaults now match the ANSI specification.

•	A default color map is now provided.

•	Polymarkers are now rendered.

•	Text support has improved.

ThumbsPlus now supports WPG files that have transformed and rotated groups and complex polygons.

FIF and DXF files that previously caused ThumbsPlus to crash now result in an error report instead.

ATM font support improvements, including support for Multiple Master fonts and instances (.PSS)

Bi-level TIFF files may now be saved with Packbits compression. Version 3.0d would save them as CCITT group 4 instead.


Problems Fixed	3.0e

•	Volume name matching (for finding thumbnails for disks) has been relaxed to help problems with removable (some Zip volumes), network, and disks shared between operating systems.

•	Several problems in ThumbsPlus and Windows have been worked-around so that thumbnails don't appear to need updating when they are current (spurious red dots). This included problems with Windows time reporting and the TZ environment variable.

•	Adding and removing fonts on NT 4.0 now properly updates the registry so that the fonts are available after system restart.

•	In the view window, Zoom In can now operate to 16x (except on Windows 3.1).

•	Installation now adds the "Add/Remove Program" registry entry regardless of whether the program is added to the Start menu.

•	The filename is changed correctly in a view window after renaming.

•	Grayed folders are shown for "orphaned" directories if Show Orphaned Thumbnails is set from Options | Preferences | General.

•	The keystrokes for some menu items were corrected.

•	Creating a database with thumbnails of odd widths (actually, not divisible by 4) no longer causes strange problems or crashes.


File Support Improvements	3.0d

TIFF formats are now supported:

•	RGB TIFF files with invalid strip sizes (i.e., Micrografx Picture Publisher)

•	4-plane 1-bit files, with or without color maps

•	Grayscale TIFF files are no longer written with a color map

BMP formats are now supported:

•	16 bits per pixel formats, with or without bit field masks

•	32 bits per pixel formats, with or without bit field masks

GIF file improvements:

•	When set to load as "Images Only" (Options | File Loading • GIF), each image is loaded as a separate image page.

•	An option was added (Options | Save As | GIF) to minimize the size of saved GIF files. This option sets the color depth to the minimum number of bits required to represent the image, sometimes resulting in a somewhat smaller file size.

•	GIF animations and multi-image files are now supported on Windows 3.1/Win32s.

PFB files [image]: Files with an internal format different from Adobe's now work properly.

TTF files: Files with a full name longer than 32 characters are now supported.

ZIP file support improvements [image]:

•	Encrypted ZIP files can now be read.

•	ZIP files can be deleted from the directory list.

•	ZIP error messages are now shown in the "Errors Encountered" area of the progress box.


View Window Functions	3.0d

Wallpapering functions (View | Wallpaper | Center, etc.) were added to the view window, allowing you to wallpaper with the current image.

File | Next File and File | Previous File now adjust the currently selected file in the main window if only a single file is selected. If multiple files are selected, the functions advance through only the selected files.

A View All Selected option was added to Options | Preferences • General to control whether all or only the first file is viewed when multiple are selected. (Previous versions displayed all; now the default is to only show the first).

Edit | Thumbnail and Edit | Copy will now operate on the entire image if nothing is selected.


Miscellaneous New Features	3.0d

Picture | Stretch Wallpaper was added (functional only on Windows 95 / NT 4.0).

Control wallpaper file location. You can control the location of the file used for wallpapering. (By default, ThumbsPlus places the file ~WALLPAP.BMP in the current TEMP directory). To change this behavior, add an entry to the THUMBS.INI file as follows:

[Wallpaper]
Filename=C:\TEMP\Wallpaper.bmp

Windows NT 4.0 support for:

•	Recycle bin

•	New format for database Save As dialog box

•	System menu icons

•	Wallpapering

•	Font installation / removal

Network drives are no longer scanned on startup, but treated more like removable disks. This generally improves startup times, and eliminates long delays when a network drive is no longer available.

Thumbnail image cache. This can improve display performance, especially on systems with slow CPUs or non-accelerated video adapters. The size of the cache is selected in Options | Preferences • Advanced.

Picture | Properties • Physical now shows the file attributes (hidden, system, read-only, etc.), and shows the complete file name.

Access to keywords is much faster than before (5x to 10x) when large numbers of keywords have been defined. This improves performance for Picture | Assign Keyword, Picture | Find and Options | Database | Edit Keywords.


Problems Fixed	3.0d

•	Several problems displaying GIF files, especially on 8-bit displays, were corrected.

•	Reduce to Fit (Options | Preferences • Slide Show) now works properly in the slide show.

•	Several missing help links were corrected.

•	Several view window shortcut keys that did not work (F9, Delete) were corrected.

•	Space now advances a slide show.

•	When batch editing using an 8-bit median cut quantization, ThumbsPlus would ask for each image whether you wanted to proceed. Now, in batch mode, no warning is issued.

•	Multi-palette GIF files were displayed and thumbnailed incorrectly when using an 8-bit (256 color) display driver.

•	Saving the start-up directory on a removable or network drive now works properly.

•	Network installations did not properly locate the THUMBS.FLT file, so filters were not available.

•	Network installations did not install DECO_32.DLL.

•	Picture | Annotate now functions properly.

•	Repairing the database would, under some conditions, not repair the volume records, resulting in no thumbnails displayed.

•	Dithering to a grayscale palette produces better results.

•	Cinepak and Indeo palettes are now loaded correctly when selected directly from the palette list in Image | Color Depth.

•	The number of colors (Image | Count Unique Colors) was sometimes incorrect for 4 bits per pixel images.

•	Directory color codes for ZIP files are now updated properly when thumbnails are made.

•	More accurate error messages are provided for resource low conditions.

•	The Slide Show would sometimes cause faults when run from an off-line volume.

•	File | Delete Directory now uses the recycle bin, if enabled from Options | Preferences • General.


Miscellaneous New Features	3.0c

Slide show MIDI background music. You can play a MIDI file in the background while viewing a slide show. Just name the file SLIDE.MID and place it in the directory with the images.

WAV files may be associated with files in the slide show. Any WAV file with the same name as the image will be played when that image is displayed. For example, for IMAGE.BMP, the corresponding WAV file would be IMAGE.WAV.

A "Yes if same" button was added to the Replace Confirmation dialog, so that only identical files are overwritten when moving.

An option for displaying thumbnails at 75% size was added. This option is available on the Options | Thumbnail Size menu, or in the Options | Preferences • File List dialog box.

Additional buttons (filter, comment) are available for the view window toolbar. You can add these buttons to the toolbar using View | Customize Toolbar.

Reduce to fit option for view window and slide show. You may now select "Reduce to fit" as the initial size option for the view window and slide show. This option causes ThumbsPlus to enable stretching of an image only if it is larger than the displayable area in the window (or screen).

View window status line improvements. The palette index now displays with the RGB value in the view window status line for pixels in color-mapped images, and Fit and Wid show in the zoom box when Stretch to Fit Window or Stretch to Fit Width are enabled.

File names may be left justified. There is now an option in Options | Preferences • File List to left-justify, rather than center, file names in the file list.

The Help file has been updated.


New File Types Supported	3.0c

Support for several file types has been added in version 3.0c. Each has an entry in the on-line help file describing its capabilities.

SBIG (Santa Barbara Instruments Group astronomical images) support (read)

FIF (Iterated Systems) support (read)

KIZ (Kodak Postcard) support (read image only)

DCX (Multi-page PCX files) (read)

Note: KDC (Kodak Digital Camera) support has been delayed because the 32-bit library is not yet available from Kodak.


File Support Improvements	3.0c

•	L*a*b color space is supported in PSD and TIFF files.

•	PSD files with multiple extra channels are supported (the extra channels are ignored)/

•	GIF files may be loaded in several ways (Options | File Loading • GIF), including animated display support (Win 95/NT only).

•	You can select the transparent color directly from the preview image in the GIF Save Options dialog box, rather than having to use the drop-down color palette.

•	A user interface is now available (Options | File Loading • RAW) for configuring RAW file types


Multi-page File (DCX, TIFF) Support	3.0c

TIFF and DCX files containing multiple images may now be accessed from ThumbsPlus. The title bar shows the current page and number of pages in the file, and there are several menu options and toolbar buttons available for use with multi-page files:

Edit | Next Page - Advances to the next sequential image in the file.

Edit | Previous Page - Backs up to the prior image.

Edit | Go to Page - Allows you to jump to a specific image.

Edit | Split Pages - Splits the images into individual files.


View Window File Functions	3.0c

Now you can perform some file functions directly from the view window. Some users have requested these features be incorporated into the slide show; however, I think having them available from a regular view window allows more flexibility and does not limit Cerious Software's options for future slide show enhancements.

Essentially, when you've opened a view window, you can advance through the current directory of files using the SPACE key, or backwards using the BACKSPACE key. To reduce confusion, ThumbsPlus will not advance past the last file in the current file list, or backward beyond the first; in other words, the next/previous functions do not wrap around.

The current file list (in the main ThumbsPlus window) is used to perform the file changes. Note that if you change directories or re-order the file list, "Next file" and "Previous file" will return a file at the position in the new display. Additionally, files added by other programs may change the file list.

The following functions are available:

File | Next file	SPACE

File | Previous file	BACKSPACE

File | Copy file	F5

File | Move file	Shift+F5

File | Rename file	Ctrl+Shift+F5

File | Delete file	DELETE

•	Some old-style BMP files were not handled.

•	Help shortcuts (both by F1 and the [Help] button) did not work from many dialog boxes.

•	The Confirm File Replace dialog would cause a GPF if canceled (via [x] or ESC).

•	Changing only the case of a keyword (i.e., JPG to jpg) would remove the keyword.

•	Using CTRL+SHIFT+P to save the current window position did not work.

•	Using the keyboard (CTRL+SHIFT+Z) to reload a JPEG image caused it to be loaded 1/2 size.

•	If the "working" or "starting" directory was other than the installation directory, ThumbsPlus could not locate the help file.

•	The current monitor gamma setting was not read at program startup.

•	The Options | File Loading property sheet did not remember the last tab selected.

•	Selecting APPLY in Options | File Loading • PhotoCD would close the dialog.

•	Trying to 'save as' a 24-bit bitmap after last saving a GIF file no longer results in an error.

•	Startup via a UNC (network) name caused the directory list to display incorrectly.

•	Removing all thumbnails from the last removable volume would mess up the directory list.

•	Some invalid JPEG files which earlier (2.x) versions could read were not handled in 3.0.

•	Rewriting thumbnails no longer erases the database annotation for the file.
