Title: The default JPEG implementation Author: Samuli Suominen Content-Type: text/plain Posted: 2012-04-24 Revision: 1 News-Item-Format: 1.0 Display-If-Installed: =media-libs/jpeg-8* libjpeg-turbo is a derivative of libjpeg that uses MMX, SSE, SSE2, and NEON SIMD instructions to accelerate baseline JPEG compression/decompression by about 2-4x on amd64, arm and x86 platforms. It is based on libjpeg/SIMD but has numerous enhancements. All users are recommended to migrate: # emerge --deselect media-libs/jpeg # emerge --oneshot media-libs/libjpeg-turbo media-libs/jpeg:0 will be left in tree as a fallback implementation.
