Kurz:         PhotoCD Anzeiger/Konverter (für AGA)

PhotoCDAGA is a viewer/converter for pictures in the PhotoCD format. It is
based on the sources of the program "hpcdtoppm" written by Hadmut Danisch.

Advantages of PhotoCDAGA:

- high picture quality gained by using the overskip mode and map-files
  (probably better than with all other programs)
- it does not cost you anything
- complete source code is included, it can be compiled with all C compilers on
  the Amiga
- high speed (it is compiled with gcc 2.7.0, a part of it is written directly
  in assembly language)
- saving in ppm-format is possible to allow conversion into other picture
  formats
  (e.g. to IFF-ILBM with ppm2AGA or to JPEG with cjpeg)
  In the NETPBM package you can find converters for almost all formats.
  (Aminet: gfx/pbm)

Disadvantages: (sorry)

- needs lot of memory
- not very comfortable (shell command)
- resolutions higher than Base (512x768) are not supported
  (you have to use hpcdtoppm, the original, in this case)

History
*******

1.0 - 20-November-1994

    - first public release

1.1 - 11-April-1995

    - ixemul.library is not needed any more
    - a stack size of 4000 bytes is enough
    - when moving the picture screen around the errors at the left border
      will be much smaller
    - better and faster screen opening
    - added 16-pictures-overview (option -0 n)

1.2 - 18-October-1995

    - compiled with gcc 2.7.0 and libnix 1.0
    - a fast chunky to planar routine is used for screen rendering, this makes
      the display much faster
    - added -orig option to use system functions for screen rendering
    - the 16-pictures-overview will always use the "topaz 8" font
      (gives better readability)
