62999d7708 Modify the ARM64 assembly file so that it uses only syntax that the clang assembler in XCode 5.x can understand. These changes should all be cosmetic in nature-- they do not change the meaning or readability of the code nor the ability to build it for Linux. Actually, the code is now more in compliance with the ARM64 programming manual. In addition to these changes, there were a couple of instructions that clang simply doesn't support, so gas-preprocessor.pl was modified so that it now converts those into equivalent instructions that clang can handle.

ea1eea4742 Sometimes the sampling factors in grayscale images can be > 1 (for instance, if compressing using 'cjpeg -sample 2x2 -grayscale'.) Technically, sampling factors have no meaning with grayscale JPEGs, and the libjpeg decompressor ignores them in that case. Thus, the TurboJPEG decompressor should ignore them as well.

bbd9b71171 When building libjpeg-turbo on Un*x systems, INT32 is usually typedef'ed to long, not int, so we need to specify an int pointer when doing a 4-byte write to the RGB565 output buffer. On little endian systems, this doesn't matter, but when you write a 32-bit int to a 64-bit long pointer address on a big endian system, you are writing to the upper 4 bytes, not the lower 4 bytes. NOTE: this will probably break on big endian systems that use 16-bit ints (are there any of those still around?)
This patch also removes an unneeded macro from jdmerge.c.

72a3cc0ecd Fix issues with RGB565 color conversion on big endian machines. The RGB565 routines are now abstracted in a separate file, with separate little-endian and big-endian versions defined at compile time through the use of macros (this is similar to how the colorspace extension routines work.) This allows big-endian machines to take advantage of the same performance optimizations as little-endian machines, and it retains the performance on little-endian machines, since the conditional branch for endianness is at a very coarse-grained level.

Subject: [PATCH] ARM: Faster NEON yuv->rgb conversion for Krait and Cortex-A15

The older code was developed and tested only on ARM Cortex-A8 and ARM Cortex-A9.
Tuning it for newer ARM processors can introduce some speed-up (up to 20%).

The performance of the inner loop (conversion of 8 pixels) improves from
~27 cycles down to ~22 cycles on Qualcomm Krait 300, and from ~20 cycles
down to ~18 cycles on ARM Cortex-A15.

The performance remains exactly the same on ARM Cortex-A7 (~58 cycles),
ARM Cortex-A8 (~25 cycles) and ARM Cortex-A9 (~30 cycles) processors.

Also use larger indentation in the source code for separating two independent
instruction streams.

eb66974f3a Ensure that tjFree() is used for any JPEG buffers that might have been dynamically allocated by the compress/transform functions. To keep things simple, we use tjAlloc() for the statically-allocated buffer as well, so that tjFree() can always be used to free the buffer, regardless of whether it was allocated by tjbench or by the TurboJPEG library. This fixes crashes that occurred on Windows when running tjunittest or tjbench with the -alloc flag.

55e328ecb8 Revert r1335 and r1336. It was a valiant effort, but on Windows, xmm8-xmm15 are non-volatile, and the overhead of pushing them onto the stack at the beginning of each function and popping them at the end was causing worse performance (in the neighborhood of 3-5%) than just using the work areas and limiting the register usage to xmm0-xmm7. Best to leave the SSE2 code alone. We can optimize the register usage for AVX2, once that port takes place.

Disable the tiling feature in TJBench whenever dynamic buffer allocation is enabled (because the tiling feature requires a separate buffer for each tile, using it successfully with dynamic buffer allocation would require a separate TurboJPEG compressor instance for each tile, and it's not worth going to that trouble right now.)

cce13c767e Subtle point, but dest->outbuffer is a pointer to the address of the JPEG buffer, which is stored in the calling program. Thus, *(dest->outbuffer) will always equal *outbuffer. We need to compare *outbuffer with dest->buffer instead to determine if the pointer is being reused.

5de454b291 libjpeg-turbo has never supported non-ANSI compilers, so get rid of the crufty SIZEOF() macro. It was not being used consistently anyhow, so it would not have been possible to build prior releases of libjpeg-turbo using the broken compilers for which that macro was designed.

976fd9687e The x86/x86-64 SIMD extensions were originally designed to accommodate changing the value of RGB_*, but this apparently broke when RGB-to-gray colorspace conversion was accelerated. Further, the ARM NEON extensions have always assumed that JCS_RGB behaves identically to JCS_EXT_RGB. Rather than fix these issues, it makes more sense to just stop claiming that we support changing the values of RGB_*, since doing so is no longer necessary.

715bb41ead Port the more accurate (and slightly faster) floating point IDCT implementation from jpeg-8a and later. New research revealed that the SSE/SSE2 floating point IDCT implementation was actually more accurate than the jpeg-6b implementation, not less, which is why its mathematical results have always differed from those of the jpeg-6b implementation. This patch brings the accuracy of the C code in line with that of the SSE/SSE2 code.

24e92e9fc0 Using subdirectories unfortunately opened up a can of worms. In order to prevent object name conflicts, it is necessary to use the subdir-objects automake directive, but it simply doesn't work right on some of the versions of automake we still have to support. Another option would be to add a separate Makefile.am file to each subdirectory, but that requires maintaining a completely different set of build rules for each one. Fortunately, however, we're in the 21st century now, so we can use filenames longer than 8.3.

b0a9cca1e3 Replace our custom version of Android.mk with instructions on how to build a libjpeg-turbo SDK for Android using autotools. Upon consulting with AOSP, it appears that Android.mk isn't really necessary except when building libjpeg-turbo for use by the Android platform itself, and it makes more sense for them to maintain the makefile for that purpose rather than for it to be upstreamed. ndk-build has serious limitations that prevent it from being used to generate static libjpeg-turbo libraries (mainly, it isn't possible to combine pre-built objects from one module into a static library for another module, which is necessary because the SIMD extensions sometimes have to be built with different CFLAGS than the rest of the code.) In general, it's just better not to introduce a new build system.

-- Auto-generates HAVE_LOCALE_H macro and adds it to jconfig.h (this is used by rdjpgcom.c.)
-- Reconciles the description and ordering of macros between config.h.in and jconfig.h.in, so the two files can be easily diffed.
-- Eliminates the use of the autoheader-generated config.h in the project and moves relevant internal-only macros into a new file, jconfigint.h.  This is to avoid "already defined" warnings in files that were including both config.h (to get the internal autotools package information or the INLINE definition) and jconfig.h.

beb0b33764 Work around an issue in Visual C++ 2010 and 2013 that was causing the 256-bit bitmap test in the regression tests to fail. More specifically, when optimization is enabled in these versions of Visual C++, the optimizer seems to get confused by the following code block:
delta = cur0 * 2;
       cur0 += delta;          /* form error * 3 */
       errorptr[0] = (FSERROR) (bpreverr0 + cur0);
       cur0 += delta;          /* form error * 5 */
       bpreverr0 = belowerr0 + cur0;
       cur0 += delta;          /* form error * 7 */

Each time cur0 is incremented by delta, the compiled code doubles the value of delta (WTF?!)  Thus, by the time the end of the block is reached, cur0 is equal to 15 times its former self, not 7 times its former self as it should be.  At any rate, it was a lot simpler to just refactor the code so that it uses multiplication.

b53f410228 Actually, the issue with nightshot_iso_100 is unrelated to the image size. Reducing the size to 128x95, the same size as vgl_6548_0026, does not eliminate the problem. The issue seems to always occur when decompression scaling is enabled. It is unclear at this point whether this is a bug or expected behavior, but the pixels generated by the split decompression functions appear correct. They are just slightly different (but not visibly so) from the pixels generated by the monolithic decompression function.

95e4cb2060 Since we now have a complete set of YUV functions, TJBench can be greatly simplified. It now tests YUV encoding/decoding as an intermediate step of JPEG compression/decompression, which eliminates the need for a separate YUV mode. Several other things have been streamlined in the process.

CMake 2.8.8 and later seem to work fine with this patch. This patch also updates the minimum required version to 2.8.8, because 2.8.8 fixed another issue that was preventing the SIMD code from building under MSVC 2010 and later.

7d9f758e52 For now, punt on trying to support fancy upsampling in tjDecodeYUV(). Fancy upsampling requires context rows and other refinements, which are difficult to implement correctly with the algorithm we're using. Longer-term, supporting fancy upsampling would probably require using the main buffer that libjpeg allocates.

c90144950f When tjDecodeYUV() is used with a "fresh" decompressor instance (one that hasn't been previously used to decompress a JPEG image), then it needs comps_in_scan, data_precision, and the quantization tables to be defined. This patch also extends TJUnitTest to check for this error.

20e158dcb7 Silence valgrind false positives about uninitialized values. Even with this patch, valgrind still complains about uninitialized values when decompressing or decoding to a buffer with an alpha-enabled colorspace. Not sure why this happens, but it occurs in libjpeg-turbo 1.3 as well, and only when the x86/x86-64 SIMD code is being used. It is my belief that these remaining warnings are also false positives, because if the output buffer is memset to all 0's prior to invoking tjDecodeYUV()/tjDecompress(), no errors are reported. If any of the alpha channel bits were in fact not being initialized, then they would still be 0 after invoking tjDecodeYUV()/tjDecompress(), and TJUnitTest would report an error.

38c9970b95 Fix an issue that prevented tjEncodeYUV3() and TJCompressor.encodeYUV() from working properly if the source image was very tiny. Basically, jpeg_start_compress() was attempting to write the JPEG headers, which was overrunning the YUV buffer. This patch removes the call to jpeg_start_compress() in tjEncodeYUV3() and replaces it with calls to the individual routines that are necessary to initialize the color converter and downsampler. TJUnitTest has also been modified to test for this condition (the buffer size regression test now works in YUV mode.)

d9712ed14b Further examination of the code reveals that this change is unnecessary. The histogram stores a count of each color in the image, so it will always contain at least one non-zero element, and thus the total can never be zero. Since the histogram is generated from the image data and not read from the header, there is no chance that header corruption would affect it.

490c7f955a Fix a couple of issues with return value checking. JFREAD(), which wraps fread(), will never return -1. fread() will instead return 0 or a short object count if an error occurs, and ferror() will return 1 in that case. The second issue was that we were assigning the return value of ftell() to an unsigned long prior to checking the value, so the value would never be < 0 if an error occurred. It would instead be (unsigned long)-1.

8ca34d4b33 Due to the way in which the configure script silently falls back to a non-SIMD build if SIMD can't be enabled, we accidentally released iOS ARM v7 and v7s binaries in 1.3.0 that did not contain NEON SIMD code, because gas-preprocessor.pl wasn't in the PATH. In order to prevent this from happening again, specifying --with-simd now has the effect of forcing a SIMD build, and if this argument is specified, any issues encountered while enabling SIMD are treated as fatal.

1.4.0
=====
[1] Fixed a build issue on OS X PowerPC platforms (md5cmp failed to build
because OS X does not provide the le32toh() and htole32() functions.)
[2] The non-SIMD RGB565 color conversion code did not work correctly on big
endian machines. This has been fixed.
[3] Fixed an issue in tjPlaneSizeYUV() whereby it would erroneously return 1
instead of -1 if componentID was > 0 and subsamp was TJSAMP_GRAY.
[3] Fixed an issue in tjBufSizeYUV2() wherby it would erroneously return 0
instead of -1 if width was < 1.
[5] The Huffman encoder now uses clz and bsr instructions for bit counting on
ARM64 platforms (see 1.4 beta1 [5].)
[6] 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.
[7] 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.
[8] cjpeg, djpeg, and jpegtran now accept an argument of -version, which will
print the library version and exit.
[9] 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.
[10] 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.
[11] 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.
[12] 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.
1.3.90 (1.4 beta1)
==================
[1] New features in the TurboJPEG API:
-- YUV planar images can now be generated with an arbitrary line padding
(previously only 4-byte padding, which was compatible with X Video, was
supported.)
-- The decompress-to-YUV function has been extended to support image scaling.
-- JPEG images can now be compressed from YUV planar source images.
-- YUV planar images can now be decoded into RGB or grayscale images.
-- 4:1:1 subsampling is now supported. This is mainly included for
compatibility, since 4:1:1 is not fully accelerated in libjpeg-turbo and has no
significant advantages relative to 4:2:0.
-- CMYK images are now supported. This feature allows CMYK source images to be
compressed to YCCK JPEGs and YCCK or CMYK JPEGs to be decompressed to CMYK
destination images. Conversion between CMYK/YCCK and RGB or YUV images is not
supported. Such conversion requires a color management system and is thus out
of scope for a codec library.
-- The handling of YUV images in the Java API has been significantly refactored
and should now be much more intuitive.
-- The Java API now supports encoding a YUV image from an arbitrary position in
a large image buffer.
-- All of the YUV functions now have a corresponding function that operates on
separate image planes instead of a unified image buffer. This allows for
compressing/decoding from or decompressing/encoding to a subregion of a larger
YUV image. It also allows for handling YUV formats that swap the order of the
U and V planes.
[2] Added SIMD acceleration for DSPr2-capable MIPS platforms. This speeds up
the compression of full-color JPEGs by 70-80% on such platforms and
decompression by 25-35%.
[3] If an application attempts to decompress a Huffman-coded JPEG image whose
header does not contain Huffman tables, libjpeg-turbo will now insert the
default Huffman tables. In order to save space, many motion JPEG video frames
are encoded without the default Huffman tables, so these frames can now be
successfully decompressed by libjpeg-turbo without additional work on the part
of the application. An application can still override the Huffman tables, for
instance to re-use tables from a previous frame of the same video.
[4] The Mac packaging system now uses pkgbuild and productbuild rather than
PackageMaker (which is obsolete and no longer supported.) This means that
OS X 10.6 "Snow Leopard" or later must be used when packaging libjpeg-turbo,
although the packages produced can be installed on OS X 10.5 "Leopard" or
later. OS X 10.4 "Tiger" is no longer supported.
[5] The Huffman encoder now uses clz and bsr instructions for bit counting on
ARM platforms rather than a lookup table. This reduces the memory footprint
by 64k, which may be important for some mobile applications. Out of four
Android devices that were tested, two demonstrated a small overall performance
loss (~3-4% on average) with ARMv6 code and a small gain (also ~3-4%) with
ARMv7 code when enabling this new feature, but the other two devices
demonstrated a significant overall performance gain with both ARMv6 and ARMv7
code (~10-20%) when enabling the feature. Actual mileage may vary.
[6] Worked around an issue with Visual C++ 2010 and later that caused incorrect
pixels to be generated when decompressing a JPEG image to a 256-color bitmap,
if compiler optimization was enabled when libjpeg-turbo was built. This caused
the regression tests to fail when doing a release build under Visual C++ 2010
and later.
[7] Improved the accuracy and performance of the non-SIMD implementation of the
floating point inverse DCT (using code borrowed from libjpeg v8a and later.)
The accuracy of this implementation now matches the accuracy of the SSE/SSE2
implementation. Note, however, that the floating point DCT/IDCT algorithms are
mainly a legacy feature. They generally do not produce significantly better
accuracy than the slow integer DCT/IDCT algorithms, and they are quite a bit
slower.
[8] Added a new output colorspace (JCS_RGB565) to the libjpeg API that allows
for decompressing JPEG images into RGB565 (16-bit) pixels. If dithering is not
used, then this code path is SIMD-accelerated on ARM platforms.
[9] Numerous obsolete features, such as support for non-ANSI compilers and
support for the MS-DOS memory model, were removed from the libjpeg code,
greatly improving its readability and making it easier to maintain and extend.
[10] Fixed a segfault that occurred when calling output_message() with msg_code
set to JMSG_COPYRIGHT.
[11] Fixed an issue whereby wrjpgcom was allowing comments longer than 65k
characters to be passed on the command line, which was causing it to generate
incorrect JPEG files.
[12] Fixed a bug in the build system that was causing the Windows version of
wrjpgcom to be built using the rdjpgcom source code.
[13] Restored 12-bit-per-component JPEG support. A 12-bit version of
libjpeg-turbo can now be built by passing an argument of --with-12bit to
configure (Unix) or -DWITH_12BIT=1 to cmake (Windows.) 12-bit JPEG support is
included only for convenience. Enabling this feature disables all of the
performance features in libjpeg-turbo, as well as arithmetic coding and the
TurboJPEG API. The resulting library still contains the other libjpeg-turbo
features (such as the colorspace extensions), but in general, it performs no
faster than libjpeg v6b.
[14] Added ARM 64-bit SIMD acceleration for the YCC-to-RGB color conversion
and IDCT algorithms (both are used during JPEG decompression.) For unknown
reasons (probably related to clang), this code cannot currently be compiled for
iOS.
[15] Fixed an extremely rare bug that could cause the Huffman encoder's local
buffer to overrun when a very high-frequency MCU is compressed using quality
100 and no subsampling, and when the JPEG output buffer is being dynamically
resized by the destination manager. This issue was so rare that, even with a
test program specifically designed to make the bug occur (by injecting random
high-frequency YUV data into the compressor), it was reproducible only once in
about every 25 million iterations.
[16] Fixed an oversight in the TurboJPEG C wrapper: if any of the JPEG
compression functions was called repeatedly with the same
automatically-allocated destination buffer, then TurboJPEG would erroneously
assume that the jpegSize parameter was equal to the size of the buffer, when in
fact that parameter was probably equal to the size of the most recently
compressed JPEG image. If the size of the previous JPEG image was not as large
as the current JPEG image, then TurboJPEG would unnecessarily reallocate the
destination buffer.

Installation Directory
======================
This document assumes that libjpeg-turbo will be installed in the default
directory (/opt/libjpeg-turbo on Un*x and Mac systems and
c:\libjpeg-turbo[-gcc][64] on Windows systems. If your installation of
libjpeg-turbo resides in a different directory, then adjust the instructions
accordingly.
=============================
Replacing libjpeg at Run Time
=============================
Un*x
----
If a Un*x application is dynamically linked with libjpeg, then you can replace
libjpeg with libjpeg-turbo at run time by manipulating LD_LIBRARY_PATH.
For instance:
[Using libjpeg]
> time cjpeg <vgl_5674_0098.ppm >vgl_5674_0098.jpg
real 0m0.392s
user 0m0.074s
sys 0m0.020s
[Using libjpeg-turbo]
> export LD_LIBRARY_PATH=/opt/libjpeg-turbo/{lib}:$LD_LIBRARY_PATH
> time cjpeg <vgl_5674_0098.ppm >vgl_5674_0098.jpg
real 0m0.109s
user 0m0.029s
sys 0m0.010s
({lib} = lib32 or lib64, depending on whether you wish to use the 32-bit or the
64-bit version of libjpeg-turbo.)
System administrators can also replace the libjpeg symlinks in /usr/lib* with
links to the libjpeg-turbo dynamic library located in /opt/libjpeg-turbo/{lib}.
This will effectively accelerate every application that uses the libjpeg
dynamic library on the system.
Windows
-------
If a Windows application is dynamically linked with libjpeg, then you can
replace libjpeg with libjpeg-turbo at run time by backing up the application's
copy of jpeg62.dll, jpeg7.dll, or jpeg8.dll (assuming the application has its
own local copy of this library) and copying the corresponding DLL from
libjpeg-turbo into the application's install directory. The official
libjpeg-turbo binary packages only provide jpeg62.dll. If the application uses
jpeg7.dll or jpeg8.dll instead, then it will be necessary to build
libjpeg-turbo from source (see "libjpeg v7 and v8 API/ABI Emulation" below.)
The following information is specific to the official libjpeg-turbo binary
packages for Visual C++:
-- jpeg62.dll requires the Visual C++ 2008 C run-time DLL (msvcr90.dll).
msvcr90.dll ships with more recent versions of Windows, but users of older
Windows releases can obtain it from the Visual C++ 2008 Redistributable
Package, which is available as a free download from Microsoft's web site.
-- Features of the libjpeg API that require passing a C run-time structure,
such as a file handle, from an application to the library will probably not
work with jpeg62.dll, unless the application is also built to use the Visual
C++ 2008 C run-time DLL. In particular, this affects jpeg_stdio_dest() and
jpeg_stdio_src().
Mac
---
Mac applications typically embed their own copies of the libjpeg dylib inside
the (hidden) application bundle, so it is not possible to globally replace
libjpeg on OS X systems. Replacing the application's version of the libjpeg
dylib would generally involve copying libjpeg.*.dylib from libjpeg-turbo into
the appropriate place in the application bundle and using install_name_tool to
repoint the libjpeg-turbo dylib to its new directory. This requires an
advanced knowledge of OS X and would not survive an upgrade or a re-install of
the application. Thus, it is not recommended for most users.
========================================
Using libjpeg-turbo in Your Own Programs
========================================
For the most part, libjpeg-turbo should work identically to libjpeg, so in
most cases, an application can be built against libjpeg and then run against
libjpeg-turbo. On Un*x systems and Cygwin, you can build against libjpeg-turbo
instead of libjpeg by setting
CPATH=/opt/libjpeg-turbo/include
and
LIBRARY_PATH=/opt/libjpeg-turbo/{lib}
({lib} = lib32 or lib64, depending on whether you are building a 32-bit or a
64-bit application.)
If using MinGW, then set
CPATH=/c/libjpeg-turbo-gcc[64]/include
and
LIBRARY_PATH=/c/libjpeg-turbo-gcc[64]/lib
Building against libjpeg-turbo is useful, for instance, if you want to build an
application that leverages the libjpeg-turbo colorspace extensions (see below.)
On Un*x systems, you would still need to manipulate LD_LIBRARY_PATH or create
appropriate symlinks to use libjpeg-turbo at run time. On such systems, you
can pass -R /opt/libjpeg-turbo/{lib} to the linker to force the use of
libjpeg-turbo at run time rather than libjpeg (also useful if you want to
leverage the colorspace extensions), or you can link against the libjpeg-turbo
static library.
To force a Un*x or MinGW application to link against the static version of
libjpeg-turbo, you can use the following linker options:
-Wl,-Bstatic -ljpeg -Wl,-Bdynamic
On OS X, simply add /opt/libjpeg-turbo/lib/libjpeg.a to the linker command
line.
To build Visual C++ applications using libjpeg-turbo, add
c:\libjpeg-turbo[64]\include to the system or user INCLUDE environment
variable and c:\libjpeg-turbo[64]\lib to the system or user LIB environment
variable, and then link against either jpeg.lib (to use the DLL version of
libjpeg-turbo) or jpeg-static.lib (to use the static version of libjpeg-turbo.)

For the most part, libjpeg-turbo should produce identical output to libjpeg

following reasons:
-- The SSE/SSE2 floating point DCT implementation in libjpeg-turbo is ever so
slightly more accurate than the implementation in libjpeg v6b, but not by
any amount perceptible to human vision (generally in the range of 0.01 to
0.08 dB gain in PNSR.)
-- When not using the SIMD extensions, libjpeg-turbo uses the more accurate
(and slightly faster) floating point IDCT algorithm introduced in libjpeg
v8a as opposed to the algorithm used in libjpeg v6b. It should be noted,
however, that this algorithm basically brings the accuracy of the floating
point IDCT in line with the accuracy of the slow integer IDCT. The floating
point DCT/IDCT algorithms are mainly a legacy feature, and they do not
produce significantly more accuracy than the slow integer algorithms (to put
numbers on this, the typical difference in PNSR between the two algorithms
is less than 0.10 dB, whereas changing the quality level by 1 in the upper
range of the quality scale is typically more like a 1.0 dB difference.)
-- When not using the SIMD extensions, then the accuracy of the floating point

Use fast integer DCT (less accurate).
In libjpeg-turbo, the fast method is generally about 5-15% faster than the int
method when using the x86/x86-64 SIMD extensions (results may vary with other
SIMD implementations, or when using libjpeg-turbo without SIMD extensions.)
For quality levels of 90 and below, there should be little or no perceptible
difference between the two algorithms. For quality levels above 90, however,
the difference between the fast and the int methods becomes more pronounced.
With quality=97, for instance, the fast method incurs generally about a 1-3 dB
loss (in PSNR) relative to the int method, but this can be larger for some
images. Do not use the fast method with quality levels above 97. The
algorithm often degenerates at quality=98 and above and can actually produce a
more lossy image than if lower quality levels had been used. Also, in
libjpeg-turbo, the fast method is not fully accelerated for quality levels
above 97, so it will be slower than the int method.

.B \-dct float
Use floating-point DCT method.
The float method is very slightly more accurate than the int method, but is

We use function prototypes everywhere; we rely on automatic source code

by the simple and portable tool 'ansi2knr.c' (courtesy of Ghostscript).

ansi2knr does not transform method declarations (function pointers in

Note the set of parentheses surrounding the parameter list.
A similar solution is used for forward and external function declarations
(see the EXTERN and JPP macros).
If the code is to work on non-ANSI compilers, we cannot rely on a prototype
declaration to coerce actual parameters into the right types. Therefore, use
explicit casts on actual parameters whenever the actual parameter type is not
identical to the formal parameter. Beware of implicit conversions to "int".
It seems there are some non-ANSI compilers in which the sizeof() operator
is defined to return int, yet size_t is defined as long. Needless to say,
this is brain-damaged. Always use the SIZEOF() macro in place of sizeof(),
so that the result is guaranteed to be of type size_t.

How This API Document Is Organized</H1>
</CENTER>
This API (Application Programming Interface) document has pages corresponding to the items in the navigation bar, described as follows.<H3>
Package</H3>
<BLOCKQUOTE>
<P>
Each package has a page that contains a list of its classes and interfaces, with a summary for each. This page can contain four categories:<UL>
<LI>Interfaces (italic)<LI>Classes<LI>Enums<LI>Exceptions<LI>Errors<LI>Annotation Types</UL>
</BLOCKQUOTE>
<H3>
Class/Interface</H3>
<BLOCKQUOTE>
<P>
Each class, interface, nested class and nested interface has its own separate page. Each of these pages has three sections consisting of a class/interface description, summary tables, and detailed member descriptions:<UL>
<LI>Class inheritance diagram<LI>Direct Subclasses<LI>All Known Subinterfaces<LI>All Known Implementing Classes<LI>Class/interface declaration<LI>Class/interface description
<P>
<LI>Nested Class Summary<LI>Field Summary<LI>Constructor Summary<LI>Method Summary
<P>
<LI>Field Detail<LI>Constructor Detail<LI>Method Detail</UL>
Each summary entry contains the first sentence from the detailed description for that item. The summary entries are alphabetical, while the detailed descriptions are in the order they appear in the source code. This preserves the logical groupings established by the programmer.</BLOCKQUOTE>
</BLOCKQUOTE>
<H3>
Annotation Type</H3>
<BLOCKQUOTE>
<P>
Each annotation type has its own separate page with the following sections:<UL>
<LI>Annotation Type declaration<LI>Annotation Type description<LI>Required Element Summary<LI>Optional Element Summary<LI>Element Detail</UL>
</BLOCKQUOTE>
</BLOCKQUOTE>
<H3>
Enum</H3>
<BLOCKQUOTE>
<P>
Each enum has its own separate page with the following sections:<UL>
<LI>Enum declaration<LI>Enum description<LI>Enum Constant Summary<LI>Enum Constant Detail</UL>
</BLOCKQUOTE>
<H3>
Tree (Class Hierarchy)</H3>
<BLOCKQUOTE>
There is a <A HREF="overview-tree.html">Class Hierarchy</A> page for all packages, plus a hierarchy for each package. Each hierarchy page contains a list of classes and a list of interfaces. The classes are organized by inheritance structure starting with <code>java.lang.Object</code>. The interfaces do not inherit from <code>java.lang.Object</code>.<UL>
<LI>When viewing the Overview page, clicking on "Tree" displays the hierarchy for all packages.<LI>When viewing a particular package, class or interface page, clicking "Tree" displays the hierarchy for only that package.</UL>
</BLOCKQUOTE>
<H3>
Deprecated API</H3>
<BLOCKQUOTE>
The <A HREF="deprecated-list.html">Deprecated API</A> page lists all of the API that have been deprecated. A deprecated API is not recommended for use, generally due to improvements, and a replacement API is usually given. Deprecated APIs may be removed in future implementations.</BLOCKQUOTE>
<H3>
Index</H3>
<BLOCKQUOTE>
The <A HREF="index-all.html">Index</A> contains an alphabetic list of all classes, interfaces, constructors, methods, and fields.</BLOCKQUOTE>
<H3>
Prev/Next</H3>
These links take you to the next or previous class, interface, package, or related page.<H3>
Frames/No Frames</H3>
These links show and hide the HTML frames. All pages are available with or without frames.
<P>
<H3>
Serialized Form</H3>
Each serializable or externalizable class has a description of its serialization fields and methods. This information is of interest to re-implementors, not to developers using the API. While there is no link in the navigation bar, you can get to this information by going to any serialized class and clicking "Serialized Form" in the "See also" section of the class description.
<P>
<H3>
Constant Field Values</H3>
The <a href="constant-values.html">Constant Field Values</a> page lists the static final fields and their values.

<pre>public class <span class="strong">YUVImage</span>

<div class="block">This class encapsulates a YUV planar image and the metadata
associated with it. The TurboJPEG API allows both the JPEG compression and
decompression pipelines to be split into stages: YUV encode, compress from
YUV, decompress to YUV, and YUV decode. A <code>YUVImage</code> instance
serves as the destination image for YUV encode and decompress-to-YUV
operations and as the source image for compress-from-YUV and YUV decode
operations.
<p>
Technically, the JPEG format uses the YCbCr colorspace (which technically is
not a "colorspace" but rather a "color transform"), but per the convention
of the digital video community, the TurboJPEG API uses "YUV" to refer to an
image format consisting of Y, Cb, and Cr image planes.
<p>
Each plane is simply a 2D array of bytes, each byte representing the value
of one of the components (Y, Cb, or Cr) at a particular location in the
image. The width and height of each plane are determined by the image
width, height, and level of chrominance subsampling. The luminance plane
width is the image width padded to the nearest multiple of the horizontal
subsampling factor (2 in the case of 4:2:0 and 4:2:2, 4 in the case of
4:1:1, 1 in the case of 4:4:4 or grayscale.) Similarly, the luminance plane
height is the image height padded to the nearest multiple of the vertical
subsampling factor (2 in the case of 4:2:0 or 4:4:0, 1 in the case of 4:4:4
or grayscale.) The chrominance plane width is equal to the luminance plane
width divided by the horizontal subsampling factor, and the chrominance
plane height is equal to the luminance plane height divided by the vertical
subsampling factor.
<p>
For example, if the source image is 35 x 35 pixels and 4:2:2 subsampling is
used, then the luminance plane would be 36 x 35 bytes, and each of the
chrominance planes would be 18 x 35 bytes. If you specify a line padding of
4 bytes on top of this, then the luminance plane would be 36 x 35 bytes, and
each of the chrominance planes would be 20 x 35 bytes.</div>

/**
* This class encapsulates a YUV planar image and the metadata
* associated with it. The TurboJPEG API allows both the JPEG compression and
* decompression pipelines to be split into stages: YUV encode, compress from
* YUV, decompress to YUV, and YUV decode. A <code>YUVImage</code> instance
* serves as the destination image for YUV encode and decompress-to-YUV
* operations and as the source image for compress-from-YUV and YUV decode
* operations.
* <p>
* Technically, the JPEG format uses the YCbCr colorspace (which technically is
* not a "colorspace" but rather a "color transform"), but per the convention
* of the digital video community, the TurboJPEG API uses "YUV" to refer to an
* image format consisting of Y, Cb, and Cr image planes.
* <p>
* Each plane is simply a 2D array of bytes, each byte representing the value
* of one of the components (Y, Cb, or Cr) at a particular location in the
* image. The width and height of each plane are determined by the image
* width, height, and level of chrominance subsampling. The luminance plane
* width is the image width padded to the nearest multiple of the horizontal
* subsampling factor (2 in the case of 4:2:0 and 4:2:2, 4 in the case of
* 4:1:1, 1 in the case of 4:4:4 or grayscale.) Similarly, the luminance plane
* height is the image height padded to the nearest multiple of the vertical
* subsampling factor (2 in the case of 4:2:0 or 4:4:0, 1 in the case of 4:4:4
* or grayscale.) The chrominance plane width is equal to the luminance plane
* width divided by the horizontal subsampling factor, and the chrominance
* plane height is equal to the luminance plane height divided by the vertical
* subsampling factor.
* <p>
* For example, if the source image is 35 x 35 pixels and 4:2:2 subsampling is
* used, then the luminance plane would be 36 x 35 bytes, and each of the
* chrominance planes would be 18 x 35 bytes. If you specify a line padding of
* 4 bytes on top of this, then the luminance plane would be 36 x 35 bytes, and
* each of the chrominance planes would be 20 x 35 bytes.
