DRC 3e2cf6909c Convert JBOOLEAN_USE_MOZ_DEFAULTS into an integer "compression profile" parameter

This eliminates JBOOLEAN_USE_MOZ_DEFAULTS and replaces it with
JINT_COMPRESS_PROFILE, a more flexible and descriptive parameter.  Currently,
this new parameter works in much the same way as the old-- it changes the
behavior of jpeg_set_defaults().  It currently supports only two values
(max. compression, i.e. mozjpeg defaults, and fastest, i.e. libjpeg-turbo
defaults), but it can be extended in the future with additional profiles that
balance compression ratio with performance.

doc/html

If the output buffer in the TurboJPEG destination manager was allocated by the destination manager and is being reused from a previous compression operation, then we need to get the buffer size from the previous operation, since the calling program doesn't know the actual buffer size.

jcapistd.c

Restore backward ABI compatibility with libjpeg/libjpeg-turbo by moving the mozjpeg-specific parameters into the opaque jpeg_comp_master struct and implementing generic accessor functions for getting/setting those parameters. These functions can be used upstream, if the need for them arises in libjpeg-turbo, and they can also be easily extended to cover future extensions to the decompressor. Note that, in order to use jpeg_comp_master as a repository for extension parameters, cinfo->master is now allocated within the body of jpeg_CreateCompress(). It is later re-allocated in jinit_c_master_control(), because that function (and others in jcmaster.c) use an extended form of jpeg_comp_master, but the existing extension parameters are copied into the new master instance. Similar modifications would need to be made to the decompressor to support the same type of extension framework.

They were annoying in the libjpeg code primarily because they were not consistently used and because they were used to format as well as indent the code. In the case of TurboJPEG, tabs are used just to indent the code, so even if the editor assumes a different tab width, the code will still be readable.)

jdcol565.c

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.

jdcolext.c

2014-05-09 18:00:32 +00:00

jdcolor.c

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 fixes crashes that occurred on Windows when running tjunittest or tjbench with the -alloc flag.

Mozilla JPEG Encoder Project

This project's goal is to reduce the size of JPEG files without reducing quality or compatibility with the vast majority of the world's deployed decoders.

The idea is to reduce transfer times for JPEGs on the Web, thus reducing page load times.

'mozjpeg' is not intended to be a general JPEG library replacement. It makes tradeoffs that are intended to benefit Web use cases and focuses solely on improving encoding. It is best used as part of a Web encoding workflow. For a general JPEG library (e.g. your system libjpeg), especially if you care about decoding, we recommend libjpeg-turbo.
