[comp.graphics] Giff Questions

jcocon@hubcap.clemson.edu (James C O'Connor III, 2846) (02/26/89)

I am trying to write a Giff decoder, and I have a few questions about the unpacking part of the process.  Is there anyone with experience so I can ask these 
questions?  I don't want to waste bandwidth, so E-mail is fine (I've only used
it on the net a few times).
	My questions are:  a simple explaination of the decoding algorithm.
				(if not simple, straight forward).
			   does the encoding scheme start over at the minimum
				value in each block, or do they keep increasing?
			   I have others, but it has been a few days since I
				worked on this and I don't remember them all.
	Thanks,
	Jim O'Connor
