IFF to Colour Sun Raster Bitmap Format Version 1.31,
using Jim Kent's IFF reader code,
by Richard Frost © 1989.
-----------------------------------------------------------------------------
NOTE: This program is freely distributable PD software, so please leave my
name in the program code and in the 'usage' help screen.
-----------------------------------------------------------------------------
This program takes standard IFF format picture files and translates them
into a picture format so that they can be displayed on Colour Sun
Workstation computers. This program is HEAPS better than the one currently
on one of the latest Fish disks, as my program converts colour images into
true COLOUR images on the Sun and also now handles HAM !!.
For more information see my C - source code included.
NOTE: For large (640 X 400) pics and for those people with 512K Amiga's
I suggest you direct the output file to a disk rather then RAM.
640 X 400 images produce 256K data files!
WHAT IS INCLUDED IN THE ARCHIVE:
-------------------------------
IFFtoSUN ... The Executable!!
IFFtoSUN.c ... The MANX C source code.
jiff.o ... This is to be linked with my routine,
jiff.h ... The include file for my program.
README ... What you are reading now.
LATEST NEWS!!:
==============
- Version 1.31:
My program converts HAM images to Sun & it WORKS !! I also solved the
aspect ratio problem associated with interlaced pics, they came out twice
as high on the Sun!. Thus I simply double the image width to fix this.
If you are interested in this program, I have recently finished a program
which converts SCULPT - 4D (& 3D) 24 bitplane RGB files to COLOUR SUN
raster bitmap! This involved choosing the best 256 colours out of a possible
16 million! The program was developed on a mainframe computer at Uni and I
have not yet ported it to the Amiga. I suspect you would need ALOT of extra
memory to run the program though. My program converted 2.4 Megabytes worth
of RGB data into a Sun bitmap in approximately 71 seconds CPU time on the
Encore Multimax mainframe computer (it is now optimized !! ). I think I was
the first to do this in Adelaide !
If you are interested , please send me a message on ADAMS AMIGA bulletin
board (08-3705775) and I will reply as soon as possible. My 676 line
C program is not yet PD and I am wondering if I should make it so, else I
wouldn't mind some small (few dollars? This program was HARD WORK) donation
and I'd be pleased to give you a copy of the source code.
Enjoy!
