ΓòÉΓòÉΓòÉ 2. Description ΓòÉΓòÉΓòÉ

Galleria is a general purpose tool for the management of bitmapped images. It
provides a window for the display of bitmaps at varying resolutions. Bitmaps
can be read from the OS/2 clipboard or from disk in numerous formats. Once
loaded, the displayed image can be edited (cropped, resized, rotated etc.) and
converted to monochrome or grayscale. The result can be transferred to other
applications via the clipboard or saved on disk in a different format. High
quality printed output can also be generated.

Galleria supports a file search function to list all bitmaps available. Also, a
multi-level undo capability is provided to reverse previous edits. Concurrent
operation of most tasks (such as display, conversion, file save and printing)
is possible due to OS/2's multi-threading capability.

Galleria supports all common bitmap file formats including BMP, PCX, TIFF and
GIF. Kodak Photo-CD format is also supported for import. Refer to Supported
file formats for a list of supported file formats (for import and export).

Refer to Galleria/CM support for instructions on integrating this program with
Galleria/CM for immediate post-processing of images captured from the desktop.

Refer to How to register for license and registration information.


ΓòÉΓòÉΓòÉ 3. Instructions on use ΓòÉΓòÉΓòÉ

Galleria is designed to perform edits and conversions on existing bitmapped
images. These bitmaps are sourced from disk files or the clipboard. If you are
using Galleria/CM, a snapshot of the desktop can also be used.

A normal session involves the following three stages:

o First, load the original bitmap. If not pre-loaded by Galleria/CM, open a
  disk file (with File open or File search) or Paste in the current image from
  the clipboard.

  Refer to Supported file formats for a list of bitmap file formats currently
  supported for import.

o Once loaded, the image can be edited and/or converted as required.

  Use the Image pull-down menu to select the desired edit operation.
  Alternatively, click the right mouse button anywhere on the image to popup a
  list of the most common edit operations. The displayed image will be updated
  to reflect the cumulative result of all edits. Use Undo to revert to the
  state prior to the last edit (conditional on the Undo levels setting).

  The image can also be converted to monochrome (black and white), grayscale
  (evenly spaced shades of gray) or color (with a standard or reduced palette).
  Selecting a conversion from the Convert pull-down menu will result in the
  current image being converted. All conversions are applied to the original
  image palette.

o When all edits and/or conversions are completed, the displayed image can be
  saved to disk (with the File save or File save as) or placed in the clipboard
  (with Copy) for transfer to another application.

Galleria can process images with up to 256 colors (8-bit color) but display of
these colors will be governed by the display/driver capability. In cases where
the image palette differs from the default palette set by Presentation Manager,
image colors will be translated to the closest displayable. Check with the
supplier of your video display adapter/driver for Palette Management support.

To view images with more (or different) colors than supported, dithering can be
applied to use only those colors from the standard VGA palette. For best
results, enlarge the image to 2 or 3 times the original size, then apply the
error diffusion color conversion.

Note that Galleria optimizes the image palette by discarding unused or
duplicate entries. The actual number of colors used in the image is displayed
in the information area at the bottom of the window. Files saved by Galleria
may be smaller as a result of this palette optimization.

Refer to the online help for detailed descriptions on use of all aspects of
Galleria. Remember that pressing F1 while pull-down menus are active will
display help for entries in that menu.


ΓòÉΓòÉΓòÉ 4. File menu ΓòÉΓòÉΓòÉ

Use the File menu to transfer images to/from disk, search for images on disk or
print the current image.

o New will replace the current image. A dialog box is displayed prompting for
  the new image size and fill color. These are normally used as a base for
  subsequent Merge operations.

o Open is used to load a new image from disk. A dialog box is displayed
  prompting for the name of the file to be read from disk.

o Search is used to search a number of disks for files matching the specified
  name or partial name. A dialog box is displayed prompting for disks to be
  searched and the file name to be found.

o Save will save the current image to disk. The image will be written to a file
  with the original file name and format or those used for the last save
  operation. The current conversion options will be applied prior to the save.
  The undo stack will also be cleared.

  Note that not all read files can be saved in the same format. If no output is
  possible for the format, this option will be disabled. Use Save as to save
  with a supported format.

o Save as will display a dialog box prompting for a new file name and/or format
  prior to saving to disk as in the Save operation above.

o The List options are available when multiple files are selected with the File
  open and File search dialogs. These enable positioning within the list of
  files selected. The buttons in the information line can also be used to
  scroll up/down the list.

  An Auto show option exists to automatically show each image in the list in
  turn for the time set in the Preferences dialog. When using Auto show, images
  unable to be loaded will be skipped. Also, when the end of the list is
  reached, display will wrap around to the beginning of the list.

  To start Auto show of the listed files with a full screen display, type
  Ctrl-F-W. Pressing any key or clicking the left mouse button will abort both
  full screen display and the Auto show facility.

o Print will print the current image to a specified printer. A dialog box will
  be displayed prompting for destination and print options.

o Preferences is used to display or change preferences. A dialog box is
  displayed permitting a number of operational settings to be changed.

quality, with high resolution offering maximum quality.

Select a Border percentage to leave a blank edge along all sides of the page.
The value specified is a percentage of the page width and height.

Select the Area percentage to limit the output size. The value specified is a
percentage of the total page area. Note that the image printed may be smaller
in area than that specified if it would otherwise overlap the border above.

For fine tuning the output, the relative Color bias percentages can be changed
to lighten/darken areas of the image depending on the red/green/blue intensity
of the original. A higher bias will result in a lighter tone for areas of that
color. Additionally, the overall intensity can be changed by setting the
desired Brightness. Position the slider arm at the desired position.

Select Sharpen to print more clearly defined lines and edges at lower
resolutions.

The Color option will generate color output for printers (with appropriate
drivers) supporting this capability. This option can also be selected for
monochrome printers and may generate more acceptable output for some
driver/printer combinations.

Press OK to start printing with the options selected or Cancel to ignore
changes and abort the current print operation.

Note that the current conversion setting is ignored when printing. The image
will be printed using the original (or edited) palette if the Color option is
selected, otherwise automatically converted to monochrome.


ΓòÉΓòÉΓòÉ 4.9. Preferences ΓòÉΓòÉΓòÉ

Use the Preferences dialog to display or change personal preferences for use of
Galleria.

Choose between Standard or Alternative file dialogs. See Alternative file
dialogs for a discussion on why you may wish to choose these non-standard
dialogs.

Either No name, Full path name or Path name only can be selected.

Set the Window size option to determine whether or not the window size should
be changed to fit the loaded image. This option applies when the bitmap is
first loaded only. Note that the window will not be resized if currently
maximized.

The RGB translation setting applies to imported bitmaps with greater than 256
colors (eg. 16 and 24-bit color). When first loaded, such images can be reduced
to either 16 or 256 colors using dithering. No translation (ie. retention of
the full color spectrum) is not yet supported. Note that translation will cause
bitmaps with greater than 256 colors to take longer to load.

Set the Auto show interval to determine the (approximate) minimum time each
image is to be displayed when using the Auto show facility.

Press OK to apply the selected preferences or Cancel to ignore changes.

The current horizontal and vertical dimensions are shown when the dialog is
invoked. Overtype these values with the new dimensions desired. Alternatively,
move the Proportional scaling slider to the left/right to decrease/increase the
size while retaining the original image proportions.

The horizontal and vertical dimensions may not exceed a value of 4096.

Press OK to accept these changes or Cancel to ignore changes and exit with the
original settings.


ΓòÉΓòÉΓòÉ 7.2. Image trim ΓòÉΓòÉΓòÉ

Use the Image trim dialog to trim the image edges. This permits finer
adjustment in a cropping operation than may be possible with Image crop.

Select one or more edges to be trimmed. A strip of the set width (below) will
be cut from each of the edges selected.

Set the width to be trimmed from the above edges.

Press OK to accept these changes or Cancel to ignore changes and exit with the
original settings.


ΓòÉΓòÉΓòÉ 7.3. Image palette ΓòÉΓòÉΓòÉ

Use the Image palette dialog to change the values of individual colors in the
image palette.

A list of colors is displayed in decreasing order of frequency in the image.
The relative frequencies for each entry is displayed with the currently
selected entry indicated by a marker of the graph. The RGB component values of
the selected entry are represented by the sliders at the right.

To change a color, select that entry from the list and move each slider until
the desired new color is displayed. Any number of colors may be changed.

Note that the palette entries listed are those from the original image and
changes made with this dialog will be applied before any conversions.

Press OK to accept these changes or Cancel to ignore changes and exit with the
original settings.

The Show option has not yet been implemented.


ΓòÉΓòÉΓòÉ 8. Convert menu ΓòÉΓòÉΓòÉ

Use the Convert menu to convert the image to monochrome or grayscale or reduce
the number of distinct colors.

o Original will display the image using the original palette.

o Monochrome will convert the image using black and white colors only. The
  mapping of original colors to either black or white will be governed by the
  settings in the Convert monochrome options dialog.

  Select 2 colors to initiate the conversion.

o Grayscale will convert the image using shades of gray only. The mapping of
  original colors to the respective shade of gray will be governed by the
  settings in the Convert grayscale options dialog.

  Select 16 colors or 256 colors to initiate the conversion.

o Color will map the original colors in the image to either a fixed palette or
  a palette with less colors than the original. This can result in smaller file
  sizes and/or better display with some monitor/adapter combinations. The
  mapping of the original colors will be governed by the settings in the
  Convert color options dialog.

  Select 16 colors to initiate the conversion.

Conversions make take some time to process. To abort the current conversion,
select Original from the Convert menu. Alternatively, select another conversion
type. Changing conversion options will automatically initiate another
conversion if they apply to the current type.

Note that conversions are applied after any edits and prior to the image being
displayed, saved to disk or copied to the clipboard. Unlike Image edit
operations which are cumulative, each conversion will override the last
selected. This permits fine tuning of the results without having to revert to
the previous state.


ΓòÉΓòÉΓòÉ 8.1. Convert monochrome options ΓòÉΓòÉΓòÉ

Use the Convert monochrome options dialog to fine-tune image conversion to
monochrome (black & white).

Select the Conversion technique. Options are Threshold for a simple re-map of
each color to either black or white, or Random dither, Ordered dither or Error
diffusion to dither or digitally halftone the image using dots of black or
white.

Choosing Threshold will give a sharper image but with the loss of the tonal
range of the original. Error diffusion will more accurately preserve the
overall tone. Random dither  or Ordered dither may be more suitable for some
applications.

To fine tune the output, change the relative Color bias percentages to
lighten/darken areas of the image depending on the red/green/blue intensity of
the original. A higher bias will result in a lighter tone for areas of that
color. Additionally, the overall intensity can be changed by setting the
desired Brightness. Position the slider arm at the desired position.

Select Enhance contrast to increase the contrast of the image or Sharpen for
more clearly defined edges.  Sharpen is recommended for Random dither but not
for Ordered dither.

Press Defaults to restore the default values for all settings.

Press OK to accept these changes or Cancel to ignore changes and exit with the
original settings.


ΓòÉΓòÉΓòÉ 8.2. Convert grayscale options ΓòÉΓòÉΓòÉ

Use the Convert grayscale options dialog to fine-tune image conversion to
shades of gray.

Select the Conversion technique. Options are Threshold for a simple re-map of
each color to the closest shade of gray, or Error diffusion to dither or
digitally halftone the image using grays from the new palette. The former
method will result in a sharper image while the latter will more accurately
preserve the overall tone.

To fine tune the output, change the relative Color bias percentages to
lighten/darken areas of the image depending on the red/green/blue intensity of
the original. A higher bias will result in a lighter tone for areas of that
color. Additionally, the overall intensity can be changed by setting the
desired Brightness. Position the slider arm at the desired position.

Select Enhance contrast to increase the contrast of the image or Sharpen for
more clearly defined edges.

Press Defaults to restore the default values for all settings.

Press OK to accept these changes or Cancel to ignore changes and exit with the
original settings.


ΓòÉΓòÉΓòÉ 8.3. Convert color options ΓòÉΓòÉΓòÉ

Use the Convert color options dialog to fine-tune image conversion to a
different or reduced color palette.

Select the Conversion technique. Options are Closest color for a simple re-map
of each color to the nearest color in the new palette, or Error diffusion (fast
or normal) to dither or digitally halftone the image using colors from the new
palette. The latter method will more accurately preserve the overall color of
the original.

The Compute optimum palette option is not yet supported.

Press Defaults to restore the default values for all settings.

Press OK to accept these changes or Cancel to ignore changes and exit with the
original settings.


ΓòÉΓòÉΓòÉ 9. Window menu ΓòÉΓòÉΓòÉ

ΓòÉΓòÉΓòÉ 11. Alternative file dialogs ΓòÉΓòÉΓòÉ

Galleria supports two sets of file dialogs, Standard and Alternative

The Alternative dialogs offer the following:

o Multi-threaded operation, thus retaining the ability to interact with the
  dialog or other applications while the file list is being built.

o Emphasis on display of file names. This permits more files to be visible at
  one time and better display of the long names possible with HPFS disks.

  When multiple directory changes are necessitated, the File search dialog may
  prove more efficient in locating the desired file.

o Specification of a set of file extensions to restrict the display of files
  when no extension is specified. This permits all relevant files (with
  differing extensions) to be easily isolated from the remainder in large
  directories.

Select Preferences from the File pull-down menu to select Standard or
Alternative file dialogs.

Note that (for all formats other than OS/2 metafiles and Photo CD) Galleria
ignores the file name extension when importing or exporting files. When a file
is read, the format is determined by examining header information contained
within the file.


ΓòÉΓòÉΓòÉ 13. Galleria/CM support ΓòÉΓòÉΓòÉ

Galleria can be integrated with Galleria/CM for immediate post-processing of
images captured from the desktop.

Simply select the Editor destination in the main Options dialog. Subsequent
captures will result in Galleria being invoked with the captured image
displayed. A new Galleria window will appear for each capture.

Note that GALLERIA.EXE must reside in the same directory as GALLERCM.EXE and
the LIBPATH statement in CONFIG.SYS must contain an explicit entry for the
directory in which the Galleria and Galleria/CM DLLs reside.


ΓòÉΓòÉΓòÉ 14. Problems and diagnostics ΓòÉΓòÉΓòÉ

If the Galleria process detects an internal or external processing error, the
program will terminate.

To determine the cause of the error, restart Galleria with the -d switch
parameter (on the command line or as a parameter in the session settings) and
reproduce the sequence of events up to the failure.

This will log error information to a file GALLERIA.LOG in the same directory as
the executable. This file contains information which can be used to resolve
problems. Please record the program version number and symptoms (what action
was being performed at the time of the error) and return this information
together with the contents of GALLERIA.LOG so that the problem can be resolved.

Note that this log file will be over-written each time Galleria is started with
the -d switch. There is no performance penalty incurred in use of this error
logging facility.

Also, if Galleria should fail to read and/or display a file specifically
documented as being supported, please send this file to the address below on a
3.5 inch floppy disk (together with information on program version number,
hardware configuration etc). An updated version of Galleria will be returned.

Please send error reports or unsupported files to:

Bitware, Software & Services
P.O. Box 3097
