-/*
- * BEWARE OF KLUDGE: This subroutine is a hack for decoding illegal JPEG-in-
- * TIFF encapsulations produced by Microsoft's Wang Imaging
- * for Windows application with the public-domain TIFF Library. Based upon an
- * examination of selected output files, this program apparently divides a JPEG
- * bit-stream into consecutive horizontal TIFF "strips", such that the JPEG
- * encoder's/decoder's DC coefficients for each image component are reset before
- * each "strip". Moreover, a "strip" is not necessarily encoded in a multiple
- * of 8 bits, so one must sometimes discard 1-7 bits at the end of each "strip"
- * for alignment to the next input-Byte storage boundary. IJG JPEG Library
- * decoder state is not normally exposed to client applications, so this sub-
- * routine provides the TIFF Library with a "hook" to make these corrections.
- * It should be called after "jpeg_start_decompress()" and before
- * "jpeg_finish_decompress()", just before decoding each "strip" using
- * "jpeg_read_raw_data()" or "jpeg_read_scanlines()".
- *
- * This kludge is not sanctioned or supported by the Independent JPEG Group, and
- * future changes to the IJG JPEG Library might invalidate it. Do not send bug
- * reports about this code to IJG developers. Instead, contact the author for
- * advice: Scott B. Marovich <marovich@hpl.hp.com>, Hewlett-Packard Labs, 6/01.
