                          *** v. 1.40 Changes ***

    A 386 version is now available to registered users.
    The separate JPEG/GIF viewer version is no longer updated or included.
    This version incorporates v3b(beta) of the IJPEG group's software.
JPEG decompression in the 286 version is slightly faster than v.1.3 and
JPEG compression is roughly twice as fast.  Corrupt JPEG images can be
viewed with 2-pass quantization because of the new code.
    Clipboard support is added.  WinJPEG can now copy an image to the
clipboard in Windows bitmap and Device Independent Bitmap(DIB) formats and
it can paste an image if the clipboard contains either a Windows bitmap or
an uncompressed DIB.
    WinJPEG 1.4 can load 1-bit and 4-bit Windows .BMP files.  The "8-bit
Bitmap" can be used when you are loading 24-bit BMP files.
    The WinJPEG icon has been replaced with one that's more appropriate.
    On-line help has been added.
    The following bugs are corrected:
    - when you close WinJPEG with the system menu while it is decoding/
      encoding an image, the program would continue running.  Also, temp.
      files would be left in the temp. directory.
    - when you resize the window or when you minimize the window and restore
      it, the scroll bar-thumb's position would be lost.  Specifically, it
      would be reset to the top of the scroll bar.
    - the menu items would still be active during compression/
      decompression of an image
    - with some pictures, there was an extraneous blank vertical strip on
      the right of the displayed picture.
    - some of the buttons were missing an underlined character and the
      buttons with the underlined character didn't respond to the ALT +
      underlined character combination
    - 24-bit bitmaps did not save correctly
    The scroll bar logic makes more sense now; formerly, it would take 5
mouse clicks to reach the end of the image, regardless of the image size.
Now, the number of clicks depends on the size of the WinJPEG window and the
size of the image.  Also, clicking on the scroll bar arrow will scroll the
image by one pixel.  Many thanks to D. Yee for his suggestions and pointing
out most of the bugs listed above.
    A couple of changes were made to the Batch Conversion and Slideshow
dialog boxes.  Only files with valid file extensions, *.tga, *.gif, and
*.jpg(for slideshow only), are shown.  Also, a "*.jpg" button was added
to the Slideshow dialog box.  Pressing any of the extension buttons will
highlight the appropriate files and pressing the same button again will
unmark those files.


                          *** v. 1.30 Changes ***

    The Discrete Cosine Transform(DCT) routines were replaced with new
ones provided by Tom Lane's v3a(beta) update of the IJPEG software.  JPEG
decompression is slightly faster(it's more noticeable for large images) and
JPEG compression takes approximately the same time.
    Display of 24-bit images in 32k/64k color mode should look right if you
use the Dither24to15 option with the 8-bit Bitmap option off.  Please email
me if you have a Hicolor video card and tell me if it works or not.
    The Low Priority option didn't seem to be giving enough CPU time to other
programs so I modified it to do so.  The Low Priority switch for the viewer
was fixed; it always stayed on.
    When you change directories in the Save dialog, the suggested filename
doesn't change to the default spec(e.g. *.JPG) anymore.  Thanks to
T. Suominen for finding this bug.
    When you load a 24-bit BMP file and use RGB/HSV adjustment, WinJPEG used
to cause a UAE/GPF in some cases.
    The JPEG Options and Memory Options menu items are now under the Options
menu.


                          *** v. 1.21 Changes ***

    There was a minor problem with the resize feature: if you entered a
new height that was 4 digits long, the last digit would be truncated.  This
problem is fixed.


                          *** v. 1.20 Changes ***

    v.1.2 has much improved error handling; when an error is
encountered, WinJPEG doesn't exit.  If an error occurs while decoding an
image, you will be given the option of viewing the portion that was
successfully decoded.   Thus, you should be able to view partially
corrupt images.  Note that for corrupt JPEG images, you must use 1-pass
quantization to view them.
    There is now a "Low Priority" switch which will give more CPU time
to other programs running at the same time as WinJPEG.  This option
affects the speed of compression/decompression of JPEG images; on my
system, it slows down decompression of a JPEG image by 1-2 seconds.  The
speed cost is worth it since I can use a word processor or download a
file while WinJPEG is decoding a JPEG in the background.
    The time delay between two pictures in a slide show is now an
adjustable value between 0 and 60 seconds.
    You can load 8-bit and 24-bit Windows BMP files with no quantization
(e.g.  when you are in an 8-bit display mode and you load a 24-bit bitmap,
the bitmap won't be quantized into an 8-bit bitmap).
    The "8-bit Bitmap" option is now available in any display mode.
    Here is a list of bug fixes:
    - can load grayscale TARGA images
    - saves TARGA images in the right format
    - saves OS/2 BMP files in the correct format (I finally received my OS/2
      2.0 ES!!!)
    - should be able to view 24-bit images in a Hicolor or Truecolor display
      mode (I don't have a Hicolor card and this feature is still not tested.
      If it does or doesn't work, please send me e-mail).


                          *** v. 1.10 Changes ***

    The previous versions would eventually give an error if you viewed many
images.  This problem is fixed.


                          *** v. 1.00 Changes ***

    TARGA images can be displayed and images can be saved to TARGA format.
Unfortunately, due to memory limitations, I can't fit the TARGA code in the
plain viewer so it will let you display only JPEG and GIF files.
    I've modified the color adjustment features which now adjust the actual
color component instead of the average color component.  This way is a bit
faster than the previous method.  Also, you can change the colors in a 24-bit
bitmap.
    Batch conversion and a slideshow feature are added.  You can select
multiple GIF and TARGA files which will be converted to JPEG.  There are
convenient "*.gif" and "*.tga" buttons which select all GIFs or all TARGAs
respectively in the current directory.  The slideshow feature lets you display
GIF, TARGA, and JPEG images sequentially with a 5 second delay between each
displayed image.  The "Cycle Slideshow" option will force WinJPEG to display
the selected images continuosly in a cycle until you abort the slideshow.
    Image resizing lets you resize the image by entering the new dimensions
of the image.
    A couple of more minor fixes were made.  WinJPEG was tested with the
8514 font so everything looks fine with that font.  If you're using small
fonts or some other font, the spacing between some text messages in the dialog
boxes is wrong.  For example, in the Open Dialog Box, the "In <path>" text
incorrectly looks like "In<path>."



                          *** v. 0.95 Changes ***

    This version is no longer crippleware.  Display of JPEG images in 24-bit
mode is supported.
    WinJPEG v.0.95 can display GIF images.  It can also write images in JPEG,
GIF, Windows BMP, or OS/2 BMP format.
    A couple of image processing features were added: rotation of an image,
horizontal/vertical flip, changing the RGB in an image, and changing the
HSI in an image.
    Some minor features include an auto-resizing option(Steve Keith gets
credit for this one again) and an option to load an image into in an 8-bit
bitmap.


                          *** v. 0.92 Changes ***

    Version 3 of the Independent JPEG Group's software is now incorporated
into this version.  2-pass quantization which produces better output is now
supported.  1-pass quantization is faster than the one used in v0.91.
Dithering can be turned on/off.
    WinJPEG can swap to a temporary file if you don't have enough memory
(includes physical and virtual).  Also, using a temporary file sometimes
speeds up the decoding of a JPEG image when you don't have enough physical
memory.
    A preview option is added.  Previewing an image is 25-50% faster than
displaying a JPEG image with 2-level quantization and dithering on. Thanks
to Steve Keith for this idea.

                          *** v. 0.91 Changes ***

    A bug that causes Windows 3.0 to give a UAE was fixed.  This bug
happens after you load in an image, move down the scroll bar thumb, and
load a smaller picture with no scroll bars activated.  On 3.1, the image
is cut off with a blank margin.  Thanks to Phil Barnes for pointing this
one out.
    Another UAE that occurs when you load in a large image and you use
the scroll bars to display the upper right corner of the picture, was
fixed.
    When you resize the window to a smaller one, WinJPEG would
occasionally display a blank window instead of a loaded image.  This was
fixed too.
    In Windows 3.1, when you reduce the size of a window with no scroll
bars on, to force scroll bars to activate, and then you enlarge the
window size so the scroll bars are turned off, WinJPEG would display a
blank window.  This bug that didn't occur in Windows 3.0 was corrected.
    16-color mode is now fully tested and working.  I was surprised that
some people told me they were using this mode for viewing JPEG images
which can store up to 16 million colors and don't look very good in
16-color mode.  A UAE that occurs when you view 1024x768 images in
16-color mode(but not in 256-color mode) was fixed.
