*** 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.
