Hi,

Our company is currently in the process of developing a CD/I title.
We've recently come across a little problem with the graphics conversion
tools we've bought. These utils contain a palette-reduction algorithm that
doesn't do a very good job on converting 24-bit images to 8-bit. We'd rather 
use PBMPlus or write my own conversion util to convert TARGA-files (.TGA)
to the proprietary CLUT7 / CLUT8 CD/I format.

As you could've guessed we're in need of the exact header-info (byte-level)
so we can use our own color-reduction scheme and get better results.

So, if anyone can tell me where I could find this information or point out
books that contain this info.... please DO NOT HESITATE TO ANSWER ;-)...

Followups to this newsgroup or (preferably) by E-Mail.... 

ThanX & Happy New Year...

	Allessandro
