Re: JPEG SOF-2 Progressive Mode Decoding

I wonder, does JPEG Huffman coding use the same Huffman algorithm as the COMPRESS (gzip) algorithm? If so, I've already basically coded that for use in a Visopsys compression library. I just haven't included that stuff in a release yet, since it wasn't totally finished as a compression library. htt...

It's cool :D BTW: I think Andy can hire us and we all can help to him and develop an secured OS for the future. You know there is many operating systems already available for all users. And all has vulnerables(Because of many developer resources of every os.(and linux has an open source so people ca...

JPEG SOF-2 Progressive Mode Decoding [NEW INFO]

Here is decoding one huffmantables file also :) I found that code, probably we have to work on huffman tables which decodes in progressive mode.. I found the code below from JIG(jpeglib)'s old versions. I think we can use that and port it into visopsys easily. I think i should share this codes via p...

Re: kernel errors related to JPG images

Any luck with this JPEG code? I wonder whether a lot of the code that you'll need, like the DCT, isn't already there, and maybe it just needs to process the stream in a slightly different way? I think we need to process stream in a slightly different way. i activated SOF2 decoding by doing case JPG...
