- mgif 3.7 91/7/25
- ----------------
-
- This is a new version of mgif, a GIF viewer for monochrome monitors (only).
- There are no new features, just improvements and some bug fixes. Notable
- amongst the improvements is dynamic memory allocation. Mgif now allocates
- whatever memory is available rather than resorting to static arrays. This
- should please more than a few people.
-
- The last posted version was 3.5. Get the documentation from there. Source
- to 3.5 was also posted, though I do not have time right now to post source
- to this version. The changes are fairly small.
-
- Changes from 3.5 to 3.7:
-
- - all: everything is now maintained under RCS (thanks to apratt@atari
- for the port of RCS). Initial revs of each file correspond to 3.5's
- version numbering for each file.
-
- - flicker.c: fix flicker for SimpConv2Gray so image is not so dark.
- Also make sure last word in each pixel row gets dumped to screen
- (this only pertains to cut and zoom operations).
-
- - mgif.c: since version now uses $Id$, clean up version string by
- removing "$Id: " and " $" from string before it is used.
-
- - mgif.c: add noise, beta, etc to "what" display. Also fix size for
- new/transformed image.
-
- - mgif.c: check for color rez and abort if so.
-
- - mgif.c,process.c,readgif.c,readpi.c: add dynamic memory for arrays.
- Most changes are in mgif.c. New globals (maximg,maxraw) replace
- defines MAXIMG,MAXRAW in other files.
-
- - low.c: eliminate grid and just draw boundaries. Cursors remain
- XOR lines.
-
- - mgif.c,low.c: "fix" bug with detecting insert key during cut (I
- think this is really a bug in Alcyon).
-
- I tested this on a half dozen different GIF images, all of which were smaller
- than 640x480 and did not see any problems. Remember, this is only for GIF87a
- files, and only for 640x400 mono monitors. It will probably not run on a TT.
- with lots of memory (2MB or more) you should be able to view 1000x1000 images,
- though only 640x400 will be on the screen. There is still no way to pan
- larger images.
-
- Enjoy...
