- Notes from the Author (24-bit IFF Tool Suite) 9/21/91
- ------------------------------------------------------
-
- These three conversion programs were born out of frustration one weekend
- after experimenting with my newly-acquired copies of 3-D Professional and
- Scenery Animator. The "problem", you see, is that I wanted to render these
- images for my PC'x 1Kx768x256 VGA adaptor, and these two programs didn't
- support 256-color output. They did support every other resolution and color
- depth however, upto and including 24-bit.
-
- The solution was to convert these 24-bit images into 256-color images via
- format conversions and color reduction. I'm sure that any Amiga users that
- have to deal with the 24-bit Amiga world and 8-bit PC world in anyway will
- find value in these programs. They are:
-
- IFF24To8 -- Converts 24-bit IFF images to 8-bit IFF images,
- wonderful for viewing with DeluxePaint on a PC.
-
- Pro2BMP -- Converts 24-bit 3D-Professional format images into
- 24bit .BMP files that Microsoft Windows can understand
-
- Pro2IFF -- Converts 24-bit 3D-Professional format images into
- the more useful 24-bit IFF format.
-
- I've since found out that the next release of 3-D Professional will support
- 24-bit IFF output; oh well. Amiga users can display 24-bit images in HAM
- mode using Digi[View|Paint], and there's even a PC program in the public
- domain (HAMVGA.EXE) that will convert Amiga HAM images into 256-color IFF.
-
- ... I'll leave it as an exercise to the reader to decide whether going from
- 24-bit IFF to HAM to VGA looks as good going from 24-bit to VGA direct. See
- enclosed picture, "TAHOE.LBM" rendered by Scenery Animator and remapped to
- 8-bit using IFF24To8.
-
- FOR THE RECORD
- --------------
-
- My STB PowerGraph VGA adaptor w/1MB of RAM cost around $130. Sheesh.
-
- It's amazing how many Amiga programs are ignorant of 256-color IFF graphics
- and crash when you try to load 'em in on an Amiga.
-
- If you're routinely porting Deluxe Paint II Enhanced images to the Amiga,
- make sure you use their supplied converter utility to convert them back
- to the original Deluxe Paint II format. EA reinvented the wheel for the
- Enhanced PC version, and its compressed format is different.
