2.1.4
=====
### Significant changes relative to 2.1.3
1. Fixed a regression introduced in 2.1.3 that caused build failures with
Visual Studio 2010.
2. 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.
3. 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.
4. 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)].
5. 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.
also tested by George on PowerPC.
