+ * 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.

%description
The libjpeg-turbo package contains a library of functions for manipulating
JPEG images. It supports architecture-specific SIMD instructions,
such as SSE/SSE2/AVX2, AltiVec, NEON, MIPS DSPR2, and Loongson MMI.
%if "%{flavor}" == "libjpeg-turbo"
It also includes the following command line utilities:
djpeg - decompress a JPEG file to an image file
jpegtran - lossless transformation of JPEG files
rdjpgcom - display text comments from a JPEG file
wrjpgcom - insert text comments into a JPEG file
tjbench - a JPEG decompression/compression benchmark
