2017-03-03PR #894 (without BOOK implementation)dev-restartAntonin Descampe
2016-09-26OPENJPEG_NAMESPACE is configurable by userMathieu Malaterre
2016-09-21Fix some issues reported by Coverity Scan (#846)Stefan Weil
* test_tile_decoder: Fix potential buffer overflow (coverity) CID 1190155 (#1 of 1): Unbounded source buffer (STRING_SIZE) Using a pointer instead of buffer of fixed size avoids the limit for the length of the input file name. Signed-off-by: Stefan Weil <sw@weilnetz.de> * test_tile_encoder: Fix potential buffer overflow (coverity) CID 1190154 (#1 of 1): Unbounded source buffer (STRING_SIZE) Using a pointer instead of buffer of fixed size avoids the limit for the length of the output file name. This implies that the length can exceed 255, so the data type for variable len had to be fixed, too. Signed-off-by: Stefan Weil <sw@weilnetz.de> * openjpip: Initialize data before returning it This fixes an error reported by Coverity: CID 1190143 (#1 of 1): Uninitialized scalar variable (UNINIT) Signed-off-by: Stefan Weil <sw@weilnetz.de>
2016-09-21Fix potential out-of-bounds read (coverity) (#844)Stefan Weil
* query_parser: Fix potential out-of-bounds read (coverity) CID 1190207 (#1 of 1): Out-of-bounds read (OVERRUN) Variable i must be checked before testing query_param.box_type. Signed-off-by: Stefan Weil <sw@weilnetz.de> * jpip_parser: Fix potential out-of-bounds read (coverity) CID 1190206 (#1 of 1): Out-of-bounds read (OVERRUN) Variable i must be checked before testing query_param.box_type.

2016-09-20Disable automatic compilation of t1_generate_lutsAntonin Descampe
Fix #831
2016-09-16renamed USE_THREAD to OPJ_USE_THREADAntonin Descampe
renaming to be consistent with previous OPJ CMake options
2016-09-15Remove TODO for overflow check (#842)Matthieu Darbois
The check was already done. It’s been simplified. Reformat to get consistent style throughout the functions.
2016-09-15Add overflow checks for opj_aligned_malloc (#841)Matthieu Darbois
See https://pdfium.googlesource.com/pdfium/+/b20ab6c7acb3be1393461eb650ca8fa4660c937e/third_party/libopenjpeg20/0020-opj_aligned_malloc.patch

2016-09-08Cast to size_t before multiplicationMatthieu Darbois
Need to cast to size_t before multiplication otherwise overflow check is useless.
2016-09-08Add sanity check for tile coordinates (#823)Matthieu Darbois
Coordinates are casted from OPJ_UINT32 to OPJ_INT32 Add sanity check for negative values and upper bound becoming lower than lower bound. See also https://pdfium.googlesource.com/pdfium/+/b6befb2ed2485a3805cddea86dc7574510178ea9
2016-09-07Moved type OPJ_BITFIELD from openjpeg.h to opj_includes.hStephan Mühlstrasser
OPJ_BITFIELD is used only in internal headers and must not appear in the public openjpeg.h header.

2016-09-06fix incrementing of "l_tcp->m_nb_mcc_records" in opj_j2k_read_mcc (#820)Matthieu Darbois
2016-09-06Fix an integer overflow issue (#809)trylab

2016-09-06Fix leak & invalid behavior of opj_jp2_read_ihdr (#818)Matthieu Darbois
In case multiple ihdr box are present, only the first one shall be taken into account.
2016-09-06Add overflow check in opj_j2k_update_image_data (#817)Matthieu Darbois
2016-09-06Change 'restrict' define to 'OPJ_RESTRICT' (#816)Matthieu Darbois
Visual Studio 2015 does not pass regression tests with `__restrict` so kept disabled for MSVC. Need to check proper usage of OPJ_RESTRICT (if correct then there’s probably a bug in vc14) Closes #661
2016-08-11[Win32] Use _beginthreadex instead of CreateThread()Even Rouault
2016-07-27Unified bit-field declaration, removed tabs.Stephan Mühlstrasser
2016-07-25Create separate type for bit-fields.Stephan Mühlstrasser
The definition of bit-fields with type OPJ_UINT32 caused complilation errors on IBM iSeries, because OPJ_UINT32 is defined as uint32_t, and uint32_t is defined as unsigned long in <stdint.h>. The definition of bit-fields with an integer type of a specific size doesn't make sense anyway.
2016-07-12Fix dependency for pkg-config (issue #594) (#795)Stefan Weil
openjpeg provides libopenjp2.pc, so the require statements must refer to libopenjp2 instead of openjp2. Fixes #594 Signed-off-by: Stefan Weil <sw@weilnetz.de>

2016-05-25Use thread-pool for T1 decodingEven Rouault
2016-05-25Add opj_codec_set_threads() in public API and propagate resulting thread ↵Even Rouault
pool to tcd level By default, only the main thread is used. If opj_codec_set_threads() is not used, but the OPJ_NUM_THREADS environment variable is set, its value will be used to initialize the number of threads. The value can be either an integer number, or "ALL_CPUS". If OPJ_NUM_THREADS is set and this function is called, this function will override the behaviour of the environment variable.

2016-05-23opj_t1_decode_cblks(): tiny perf increase when loop unrollingEven Rouault
2016-05-23Tier 1 decoding: add a colflags arrayEven Rouault
Addition flag array such that colflags[1+0] is for state of col=0,row=0..3, colflags[1+1] for col=1, row=0..3, colflags[1+flags_stride] for col=0,row=4..7, ... This array avoids too much cache trashing when processing by 4 vertical samples as done in the various decoding steps.
2016-05-22Const'ify lut arrays so they are in the read-only data sectionEven Rouault
2016-05-22Reduce number of occurrences of orient function argumentEven Rouault
This is essentially used to shift inside the lut_ctxno_zc, which we can precompute at the beginning of opj_t1_decode_cblk() / opj_t1_encode_cblk()
2016-05-21Specialize decoding passes for 64x64 code blocksEven Rouault
2016-05-21Improve code generation in opj_t1_dec_clnpass()Even Rouault
Add a opj_t1_dec_clnpass_step_only_if_flag_not_sig_visit() method that does the job of opj_t1_dec_clnpass_step_only() assuming the conditions are met. And use it in opj_t1_dec_clnpass(). The compiler generates more efficient code.
2016-05-21opj_t1_updateflags(): tiny optimizationEven Rouault
We can avoid using a loop-up table with some shift arithmetics.
2016-05-21Move some MQC functions into a header for speedKal Conley
Allow these hot functions to be inlined. This boosts decode performance by ~10%.
