|
|
|
|
|
|
|
|
|
|
- Update to version 1.4.0
|
|
|
|
|
+ Fixed a build issue on OS X PowerPC platforms (md5cmp failed to build
|
|
|
|
|
because OS X does not provide the le32toh() and htole32() functions.)
|
|
|
|
|
+ The non-SIMD RGB565 color conversion code did not work correctly on big
|
|
|
|
|
endian machines. This has been fixed.
|
|
|
|
|
+ Fixed an issue in tjPlaneSizeYUV() whereby it would erroneously return 1
|
|
|
|
|
instead of -1 if componentID was > 0 and subsamp was TJSAMP_GRAY.
|
|
|
|
|
+ Fixed an issue in tjBufSizeYUV2() wherby it would erroneously return 0
|
|
|
|
|
instead of -1 if width was < 1.
|
|
|
|
|
+ The Huffman encoder now uses clz and bsr instructions for bit counting on
|
|
|
|
|
ARM64 platforms (see 1.4 beta1 [5].)
|
|
|
|
|
+ The close() method in the TJCompressor and TJDecompressor Java classes is
|
|
|
|
|
now idempotent. Previously, that method would call the native tjDestroy()
|
|
|
|
|
function even if the TurboJPEG instance had already been destroyed. This
|
|
|
|
|
caused an exception to be thrown during finalization, if the close() method had
|
|
|
|
|
already been called. The exception was caught, but it was still an expensive
|
|
|
|
|
operation.
|
|
|
|
|
+ The TurboJPEG API previously generated an error ("Could not determine
|
|
|
|
|
subsampling type for JPEG image") when attempting to decompress grayscale JPEG
|
|
|
|
|
images that were compressed with a sampling factor other than 1 (for instance,
|
|
|
|
|
with 'cjpeg -grayscale -sample 2x2'). Subsampling technically has no meaning
|
|
|
|
|
with grayscale JPEGs, and thus the horizontal and vertical sampling factors
|
|
|
|
|
for such images are ignored by the decompressor. However, the TurboJPEG API
|
|
|
|
|
was being too rigid and was expecting the sampling factors to be equal to 1
|
|
|
|
|
before it treated the image as a grayscale JPEG.
|
|
|
|
|
+ cjpeg, djpeg, and jpegtran now accept an argument of -version, which will
|
|
|
|
|
print the library version and exit.
|
|
|
|
|
+ Referring to 1.4 beta1 [15], another extremely rare circumstance was
|
|
|
|
|
discovered under which the Huffman encoder's local buffer can be overrun
|
|
|
|
|
when a buffered destination manager is being used and an
|
|
|
|
|
extremely-high-frequency block (basically junk image data) is being encoded.
|
|
|
|
|
Even though the Huffman local buffer was increased from 128 bytes to 136 bytes
|
|
|
|
|
to address the previous issue, the new issue caused even the larger buffer to
|
|
|
|
|
be overrun. Further analysis reveals that, in the absolute worst case (such as
|
|
|
|
|
setting alternating AC coefficients to 32767 and -32768 in the JPEG scanning
|
|
|
|
|
order), the Huffman encoder can produce encoded blocks that approach double the
|
|
|
|
|
size of the unencoded blocks. Thus, the Huffman local buffer was increased to
|
|
|
|
|
256 bytes, which should prevent any such issue from re-occurring in the future.
|
|
|
|
|
+ The new tjPlaneSizeYUV(), tjPlaneWidth(), and tjPlaneHeight() functions
|
|
|
|
|
were not actually usable on any platform except OS X and Windows, because
|
|
|
|
|
those functions were not included in the libturbojpeg mapfile. This has been
|
|
|
|
|
fixed.
|
|
|
|
|
+ Restored the JPP(), JMETHOD(), and FAR macros in the libjpeg-turbo header
|
|
|
|
|
files. The JPP() and JMETHOD() macros were originally implemented in libjpeg
|
|
|
|
|
as a way of supporting non-ANSI compilers that lacked support for prototype
|
|
|
|
|
parameters. libjpeg-turbo has never supported such compilers, but some
|
|
|
|
|
software packages still use the macros to define their own prototypes.
|
|
|
|
|
Similarly, libjpeg-turbo has never supported MS-DOS and other platforms that
|
|
|
|
|
have far symbols, but some software packages still use the FAR macro. A pretty
|
|
|
|
|
good argument can be made that this is a bad practice on the part of the
|
|
|
|
|
software in question, but since this affects more than one package, it's just
|
|
|
|
|
easier to fix it here.
|
|
|
|
|
+ Fixed issues that were preventing the ARM 64-bit SIMD code from compiling
|
|
|
|
|
for iOS, and included an ARMv8 architecture in all of the binaries installed by
|
|
|
|
|
the "official" libjpeg-turbo SDK for OS X.

|
|
- update to 1.3.1:
|
|
|
|
|
* Fixed a bug whereby attempting to encode a progressive JPEG
|
|
|
|
|
with arithmetic entropy coding (by passing arguments of
|
|
|
|
|
-progressive -arithmetic to cjpeg or jpegtran, for instance)
|
|
|
|
|
would result in an error, "Requested feature was omitted at
|
|
|
|
|
compile time".
|
|
|
|
|
* Fixed a couple of issues whereby malformed JPEG images would
|
|
|
|
|
cause libjpeg-turbo to use uninitialized memory during
|
|
|
|
|
decompression.
|
|
|
|
|
* Fixed an error ("Buffer passed to JPEG library is too small")
|
|
|
|
|
that occurred when calling the TurboJPEG YUV encoding function
|
|
|
|
|
with a very small (< 5x5) source image, and added a unit test
|
|
|
|
|
to check for this error.

|
|
an application was compiled.

CMYK/YCCK JPEGs whose K component is assigned a component ID
|
|
|
|
|
of 1 instead of 4.
|

|
|
- updated to 1.1.1:
|
|
|
|
|
* Fixed a 1-pixel error in row 0, column 21 of the luminance
|
|
|
|
|
plane generated by tjEncodeYUV().
|
|
|
|
|
* libjpeg-turbo's accelerated Huffman decoder previously
|
|
|
|
|
ignored unexpected markers found in the middle of the
|
|
|
|
|
JPEG data stream during decompression. It will now
|
|
|
|
|
hand off decoding of a particular block to the unaccelerated
|
|
|
|
|
Huffman decoder if an unexpected marker is found, so that
|
|
|
|
|
the unaccelerated Huffman decoder can generate an appropriate
|
|
|
|
|
warning.
|
|
|
|
|
* Fixed a bug in jpeg_read_coefficients() whereby it would
|
|
|
|
|
not initialize cinfo->image_width and cinfo->image_height
|
|
|
|
|
if libjpeg v7 or v8 emulation was enabled. This specifically
|
|
|
|
|
caused the jpegoptim program to fail if it was linked against
|
|
|
|
|
a version of libjpeg-turbo that was built with libjpeg v7 or
|
|
|
|
|
v8 emulation.
|
|
|
|
|
* Eliminated excessive I/O overhead that occurred when reading
|
|
|
|
|
BMP files in cjpeg.
