Feature changed by: nick skeen (ns89) Feature #310410, revision 4 Title: Evaluate switching to libjpeg-turbo openSUSE-11.4: Unconfirmed Priority Requester: Important Requested by: Vincent Untz (vuntz) Description: Quoting http://fedoraproject.org/wiki/Features/libjpeg-turbo: ==== libjpeg-turbo is fork of the original libjpeg project. It contains numerous performance related enhancements and is at least twice faster in JPEG compression/decompression than original libjpeg on platforms with MMX/SSE instruction set. It has same API/ABI like original libjpeg and also runs on non-SSE platforms where is around 25% faster. http://sourceforge.net/projects/libjpeg-turbo ==== We should evaluate this library and see if we can replace libjpeg with it for improved performance. Discussion: #1: Vincent Untz (vuntz) (2010-08-25 10:00:13) The formatting got messed up: libjpeg-turbo is fork of the original libjpeg project. It contains numerous performance related enhancements and is at least twice faster in JPEG compression/decompression than original libjpeg on platforms with MMX/SSE instruction set. It has same API/ABI like original libjpeg and also runs on non-SSE platforms where is around 25% faster. http://fedoraproject.org/wiki/Features/libjpeg-turbo #2: John Van Vliet (johnvv) (2010-08-29 01:11:15) no the continude use of jpg format only continues the use of a file format that should have died out a few years back + #3: nick skeen (ns89) (2010-08-29 21:19:26) (reply to #2) + Can you present a good alternative to JPEG? If somebody would make a + format with JPEG style encoding and compression I would agree with you. + But as far as I can tell it does not exist, all other mainstream + formats make use of only zlib compression. And JPEG is unfortunately + the best format for images with large amounts of color. I would be + happy if you could prove me wrong though. -- openSUSE Feature: https://features.opensuse.org/310410
