- update to 2.1.4:
* Fixed a regression introduced in 2.1.3 that caused build failures with
Visual Studio 2010.
* The tjDecompressHeader3() function in the TurboJPEG C API and the
TJDecompressor.setSourceImage() method in the TurboJPEG Java API now
accept "abbreviated table specification" (AKA "tables-only") datastreams,
which can be used to prime the decompressor with quantization and Huffman
tables that can be used when decompressing subsequent "abbreviated image"
datastreams.
* libjpeg-turbo now performs run-time detection of AltiVec instructions on
OS X/PowerPC systems if AltiVec instructions are not enabled at compile
time. This allows both AltiVec-equipped (PowerPC G4 and G5) and
non-AltiVec-equipped (PowerPC G3) CPUs to be supported using the same
build of libjpeg-turbo.
* Fixed an error ("Bogus virtual array access") that occurred when
attempting to decompress a progressive JPEG image with a height less than
or equal to one iMCU (8 * the vertical sampling factor) using
buffered-image mode with interblock smoothing enabled. This was a
regression introduced by 2.1 beta1[6(b)].
* Fixed two issues that prevented partial image decompression from working
properly with buffered-image mode:
* Attempting to call jpeg_crop_scanline() after jpeg_start_decompress()
but before jpeg_start_output() resulted in an error ("Improper call to
JPEG library in state 207".)
* Attempting to use jpeg_skip_scanlines() resulted in an error ("Bogus
virtual array access") under certain circumstances.
