38   * A subroutine library for JPEG compression and decompression.
54 Within these limits, any set of compression parameters allowed by the JPEG
70 library to implement JPEG compression within the TIFF file format.)
74 functions preprocess the image before JPEG compression or postprocess it after
82 compression side we have generally not provided low-quality choices, since
83 compression is normally less time-critical.  It should be understood that the

317 Here is a sketch of the logical structure of the JPEG compression library:
