description="
Library for JPEG images.

libjpeg-turbo is a high-speed version of libjpeg for x86 and x86-64
processors which uses SIMD instructions (MMX, SSE2, etc.) to accelerate
baseline JPEG compression and decompression.

ibjpeg-turbo is generally 2-4x as fast as the unmodified version of
libjpeg, all else being equal.
