- PM/GIF - v0.10 -4/14/88
-
- Here's the latest version of PM/GIF !! It fixes various problems
- found in the earlier release.
-
- Some of the problems fixed were:
- 1) The scrolling was off by a pixel
- 2) Repainting of the screen was messed up after the window
- was obscured by something on the desktop
- 3) Forgot to put scrollbar thumb logic in (OOPS!!)
- 4) Scrolling further than the size of a window sometimes messed
- up.
-
- Enhancements added:
- 1) All scrolling and repaint logic was reworked!! This achieved
- faster repainting, smoother scrolling and fixed some niggling
- little nasties floating around.
-
- 2) The GIF decoding part of the code has now been placed in a
- separate thread. The program will now not hog the system like
- it used to !! If the thread is not able to be opened (low
- memory, low on swap space) the program will still come up
- but the Open option on the File Menu will not work.
-
- 3) The Informational dialog box has been moved. It no longer
- comes up automatically. It is now on the main menu bar and is
- enabled when you open an image.
-
- 4) Multi Image GIF files are now supported (if you can find any!)
- I still do not utilize the Local color table for individual
- images, though. Also, you may see garbage on the screen if
- the individual images do not fill the entire screen. This IS
- being fixed. In over 200 GIFs I tested, I've only seen this
- happen twice.
-
- Yet to come:
- Heres a list of things I still plan to add to make PM/GIF
- nicer:
- 1) Color Dithering
- 2) Speedier Decompression
- 3) Enabling of all those HELP buttons that don't do a thing
- 4) File save capabilities in a variety of formats
- 5) Slide show capabilities
- 6) Local color table support
- 7) Better error handling
-
- Known Problems:
-
- The only thing I know about right now is when you don't have enough
- memory available to create the bitmap. Now OS/2 handles this pretty
- well, swaaping to disk and all. But, if you are low on memory AND
- have little or no swap room left, I just forge ahead. You will see
- garbage when the image comes up. Just pull up another image and all
- will be fine. Or you could go out and free up some space on your
- disk!! I have only seen this happen once, but the GIF was HUGE
- (880x720)!! Color is still a major issue with me as OS/2 can only
- support 16 colors at a time (EGA/VGA). The 16 color GIFs look pretty
- good but the 256 color ones look goofy! (especially flesh tones, they
- end up looking grey). The next release will definitely have some sort
- of color dithering or substitution added to it.
-
-
- Again, this is YOUR program. I've downloaded enough freeware and
- shareware, now it's my turn for a payback. ANY and ALL suggestions
- for PM/GIF are happily accepted via Compuserve (75470,716) or by
- post at the address below. PLEASE let me know what you think and
- report any new bugs you might find.
