> JPEG, GRAPHICS, JPEG release 5 Image Compression/Decompression  H This package contains C software to implement JPEG image compression andI decompression.  JPEG (pronounced "jay-peg") is a standardized compression N method for full-color and gray-scale images.  JPEG is intended for compressingH "real-world" scenes; cartoons and other non-realistic images are not itsM strong suit.  JPEG is lossy, meaning that the output image is not necessarily N identical to the input image.  Hence you must not use JPEG if you have to haveM identical output bits.  However, on typical images of real-world scenes, very M good compression levels can be obtained with no visible change, and amazingly M high compression levels are possible if you can tolerate a low-quality image. E For more details, see the references, or just experiment with various  compression settings. 
