[comp.sys.amiga] Convert 24 BIT RGB to Halfbrite 64-Color IFF; HOW????

dean@coplex.UUCP (Dean Brooks) (10/18/90)

   The subject says it all.  Are there ANY public domain programs out there
that will take a 24 BIT RGB file (like the output of DKBTrace, Turbo Silver,
etc) and convert them to 64-color Extra Halfbrite IFF?

   I have looked through hundreds of PD listings from Fred Fish, through
USENET postings, through the listings on BIX, all to no avail.  I would
write something myself, but good color coding schemes are something I
know nothing about.

   ANYONE HAVE ANY CLUES?  I KNOW something like this MUST exist...

                                    Thanks!

A round about way would be to read the RGB file into Digiview, and have it
convert it into half-brite mode. But Digiview isn't PD.

...which is why I've asked on a couple other newsgroups before about the
file specs for the 24 bit RGB format.  I would also like the filespecs 
for Dynamic Hires.

If I can get ahold of these, I could probably write a conversion program 
for at least 24-bit to DynaHires and maybe a few others.  This PD utility
_needs_ to exists, since Digi View is proprietary, and you have to buy
their digitizing hardware with it.  (I have no need for a digitizer!)
