- imShow 2.02, January 1993
-
- imShow - An OS/2 2.0 application to display pictures in the formats:
- BMP (OS/2 1.1, Windows 3 and OS/2 2.0 formats)
- GIF (only plain, non-interlaced GIF87)
- im (an image file format developed at the University of Zürich)
-
- The comments of the source code are now in english, so I think I can
- release it.
-
-
- The "new" thing on this picture viewer is the support of the OS/2 2.0
- palette manager. This means, you can see your pictures with their
- actual colors!
-
- It now has limited support on other devices than XGA that support the
- palette manager (tested on Tseng ET4000). The palette manager on this
- driver is that awfully buggy, that it is almost impossible to display
- anything at all. Raja Thiagarajan found a way to display bitmaps
- at least non-scaled (in 100% size). So that's what you can do now:
- look at this pictures as long as you don't touch the "View" menu.
- Of course on XGA and XGA-2 it still works as usual.
-
-
- Requirements:
- OS/2 2.0 with service pack installed (to get the palette manager).
- A display adapter and driver which supports 256 colors and the
- palette manager (tested on the IBM XGA and XGA-2, limited function
- on Tseng ET4000).
-
- Changes in 2.01:
- - Gif's are read in a bit faster (but still slowly).
- - Not all memory was freed when a new image was opened, resulting
- in an always increasing memory demand; This is fixed.
- - Gif's with less than 8 bit colors (e.g. 7 bit gif's) now don't
- allocate all 256 palette entries.
- - When "fit in window" was seleced, and the window had exactly
- the same dimensions as the bitmap, the image became corrupted.
- - Some code redundancies ar removed, resulting in better readable
- source code.
-
- Changes in 2.02:
- - imShow now works also on Tseng Cards (as long as you don't
- touch the "View" menu.)
- - "Under the hoods" is quite a lot of rewrite done, so maybe
- there are now some new bugs...
-
- Known bugs:
- - The shortcut "Ctrl-W" doesn't work (I have no idea why)
- - Sometimes OS/2 doesn't repaint the client area correctly,
- resulting in wrong colors on part of the image. This is a
- bug in PM.
- - Pictures can only be scaled on XGA and XGA-2 cards, not on
- any other card which supports the palette manager.
