Intel® JPEG Library 1.51

The Intel® JPEG Library (IJL) is a software library for application developers that provides high performance JPEG encoding and decoding of full color and grayscale still images.

The IJL was designed for use on Intel® architecture platforms and has been tuned for speed and efficient memory usage. Additionally, the IJL was developed to take advantage of MMX™, Streaming SIMD Extensions (SSE), and SSE-2 technology if present.

The IJL provides an easy-to-use programming interface without sacrificing low-level JPEG control to advanced developers. The IJL also includes a substantial amount of functionality that is not included in the ISO JPEG standard. This added functionality is typically necessary when working with JPEG images, and includes pre-processing and post-processing options like sampling and color space conversions.

Additional information on this software as well as other libraries is available at the Intel Performance Libraries web site.
