/* TITLE: IFF to Sun Raster Bitmap File Format. Version 1.31
by Richard Frost, © 1989.
If this is program is to be used for personal financial gain
PLEASE inform the author FIRST!
Please keep my name in this program, this is FREEWARE !!!
SOON TO BE SUBMITTED FOR INCLUSION ON THE FISH LIBRARY!!
(I hope !!)
<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
WARNING: DO NOT attempt any file conversions into
RAM DISK or any normal disk until you
are sure that the disk has the space
to hold the converted images, else
the program will crash (I couldn't be
bothered checking for this) and you will
get a friendly visit from MR GURU!
HALFBRITE NOT SUPPORTED YET!!!!
NOTE: 640 X 400 images create files that are
over 256K long! (USE 1 MEG RAM or nearly
an empty disk!)
Expect even larger than this for PAL
(typically at most, say 704 X 512 ) images.
HAM images come out OK, as the colour choice
algorithm needs some tweaking!
Expect to see even faster conversions and better
colour choice in the next versions and maybe
HALFBRITE mode.

You can mail any messages to me (RICHARD FROST) on the
'ADAM-LINK' BBS (Located in Adelaide, South Australia)
Using the IFF routines 'Jiff.c' by
Jim Kent.
HISTORY:
- Started Version 1.0 7th February 1989.
- Version 1.0 WORKED FIRST TIME WITH NON-HAM images!!!
- HAM implementation 23rd February 1989.
- Aspect ratio correction for INTERLACE added 5th March 1989
- HAM finished 5th March 1989
- HAM checked on SUN 3/60 & working 6th March 1989
- HAM colour choice algorith improved (not completed yet)
BUGS: As with all programs their complexity hides all bugs!.
- Funny things happen to memory & Workbench when input files
hack up, ie LOTS of RAM NOT reallocated, an error in the
READ IFF routine???
THANKS: I must thank my friend ROBERT WOZNIAK for the idea
behind the extra 'map_to' field in the histogram entry,
which involved mapping ALL colours ONCE before the second
pass of the screen and thus using the histogram as a look-up
table. ROBERT'S very simple (yet INCREDIBLY EFFICIENT) idea
has improved the speed of my program incredibly.
Thanks Rob !! (You are famous too now!!)
I must also thank ALEX WAKEFIELD for his patience in porting
generated SUN rasterfiles over to the SUN 3/60, and then putting
up with DISK QUOTA errors on his SUN account !!
Once the AMIGA images got onto ETHERNET, boy did they travel
to other SUNS quick !!
The Electronics Arts people who decided that there
should be ONE, and ONLY ONE standard image format on the AMIGA,
IFF !!!
INFORMATION:
I hope you find this program as useful as I did. I did it mainly because
a friend of mine at university had access to a colour Sun 3/60. If you are
not aquainted with this computer, here are some juicy specs :
Resolution: 1152 X 900 (NON INTERLACED)
Colour Pallete: 16 million colours to choose from
Number of bitplanes: 8 ( means 256 on screen colours)
This means that you can view AMIGA INTERLACED pictures in their
NON-INTERLACED form on the Sun, plus you have a VERY high resolution
which gives some pictures a photographic-like quality, (ie. the IFF
picture .. 'Legends', 'Dusky Hopping Mouse', 'Tiger' etc. !!!).
Yes, this version DOES handle HAM pics, so now all those great HAM pics
out there can be ported to SUN Workstations!!!
NOTE: I went to some effort in optimising the colour choice algorithm
as some HAM pics have LOTS of distinct on-screen colours!
The classic HAM pic of an attractive lady's face holding a
pencil near her mouth has over 1300 distinct colours, from
this I had to choose a GOOD 256 palette for the SUN. My first
attempt was reasonable but the picture still had some very
obvious colour defects for a few pixels which needed improving.
I love the idea of STANDARDISATION !
