libjpeg

libjpeg is an open source library for handling the JPEG (JFIF) image format files.

Included are the command-line tools cjpeg and djpeg for converting to and from this format, rdjpgcom and wrjpgcom to manipulate JFIF comments, and jpegtran to perform some lossless transformations on JPEG imagess.

What is new in this release:

• Support has been added for lossless coding of RGB images with significantly improved compression.
• These files are incompatible with previous versions of libjpeg, yet compatible with other JPEG standards (e.g., JPEG-LS part 2).
• Files with invalid component identifiers (such as created by Adobe PDF) are now tolerated.
• Various other enhancements and several fixes have been made.
