Description
Overview
MGA View is a small program for viewing pictures on console (linux text-mode).
The program uses mga_vid driver from mplayer, which is a special video driver
for Matrox cards. Since version 0.0.28 MGA View supports also graphics cards
other than Matrox, using framebuffer device. By now some functions
(scalling, zooming, grayscale) are available only for Matrox users, but they will
be added in future.
MGA View recognizes file format by checking its contents, not its extension,
so it can display properly a file with incorrect extension or no extension at all.

Requirements
For MGA View compilation you need following libraries in your system along
with their devel packets (see links):
- libungif & libungif-dev,
- libjpeg & libjpeg-dev,
- libpng & libpng-dev,
- zlib & zlib-dev,
- libtiff & libtiff-dev
- libMagick (ImageMagick library).
For running MGA View you need also mga_vid driver and framebuffer device
turned on.
By now MGA View was tested on:
- CPU's:
- i386 family (AMD k6-2 3dnow, AMD Duron 1 GHz, ...)
- Distributions:
- Debian (testing/unstable)
- Mandrake 7.2.
- RedHat 7.1.
However, I think that other distributions should have no problems with running it.
- Graphics cards:
- Matrox Millenium G200
- nVidia GeForce2 MX (thx for Radek)
- Riva TNT 2 (thx Verdan)
Known Bugs
- When using mga_vid: if screen resolution is 1024x768 or higher, displaying
a picture with similar size may cause segmentation fault;
- When using framebuffer: if wirtual size of the screen is larger than its real
size (and thus, more memory is allocated), the image may be not properly
displayed.
Future plans:
- making all options available for mga_vid available also for framebuffer :-)
- saving files to formats other than zmg and tga
