[comp.sys.amiga.graphics] SHAM format

ben@epmooch.UUCP (Rev. Ben A. Mesander) (06/01/91)

I'd like to write a program to convert DKB raytracer output to SHAM
format. Could someone please tell me where I can find specs on the SHAM
IFF format?

Any other suggestions for converting 24-bit files so that they look nice
on an unmodified Amiga? How about choosing the color registers for HAM
format? Does anyone have any algorithms they could share?

The 'algorithm' that we use is called ADPro, by ASDG. The art department will
convert your high resolution 24 bit image into 640x400 AHAM, the equivalent of
SHAM. Quite nice transformations.

        I've heard that when you use ADPro with AHAM, it still doesn't let
you use high resolution (?).  Which statement is true.  This person I know
was trying to specify Hi-res, Lace, AHAM and it brought up the "No more
than 16 colours" requestor.  In your post are you saying that it will make
640x400 but not HiRes?
