Huffman and quantization tables

 [1/2] from: kemp::extelligence::net at: 12-Jun-2002 11:08

Hello: I'm trying to decompress image tiles that have been delivered to a Rebol app as raw jpeg data, with separate Huffman and quantization tables. Is there any way in Rebol to decode jpeg data with separate tables rather than as an entire jpeg file? Or will I have to drop out to native code? Thanks Kemp Watson - Rebol newb

Hi Kemp, Ole Friis (I think?) has a good article on compression on the REBOLForces web site. My guess is that speed may be an issue. I've only done a simple RLE implementation myself, but I also tried some edge detection stuff and it was just way too slow to be useful. --Gregg
