Matthieu Darbois	fac916f72a	Fix PNM file reading (#847 ) Malformed PNM file could cause a crash in opj_compress. Checks were added to prevent this. Fixes #843 Updates #440	2016-09-22 00:30:34 +02:00
Stefan Weil	8715ce2749	Fix some issues reported by Coverity Scan (#846 ) * 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>	2016-09-21 21:15:25 +02:00
Stefan Weil	045aa4d9f2	Fix potential out-of-bounds read (coverity) (#844 ) * 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.

Stephan Mühlstrasser	8750e183c6	Moved type OPJ_BITFIELD from openjpeg.h to opj_includes.h OPJ_BITFIELD is used only in internal headers and must not appear in the public openjpeg.h header.	2016-09-07 08:41:01 +02:00

Stephan Mühlstrasser	54874194a8	Unified bit-field declaration, removed tabs.	2016-07-27 10:09:54 +02:00
Stephan Mühlstrasser	d2d35bf6c2	Create separate type for bit-fields. 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.	2016-07-25 20:46:11 +02:00
Even Rouault	7d3c7a345f	Be robust to failed allocations of job structures	2016-05-26 23:51:32 +02:00
Even Rouault	69497d35c0	opj_decompress: use clock_gettime() instead of getrusage() so as to get the time spent, and not to the total CPU time	2016-05-25 21:59:43 +02:00
Even Rouault	d67cd2220a	opj_decompress: add a -threads <num_threads> option	2016-05-25 21:02:07 +02:00

Even Rouault	5fbb8b2645	Use thread-pool for T1 decoding	2016-05-25 21:02:07 +02:00
Even Rouault	d4b7f03cfa	Add opj_codec_set_threads() in public API and propagate resulting thread 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.	2016-05-25 21:02:07 +02:00
Even Rouault	54179fe1d5	Add threading and thread pool API	2016-05-25 21:02:07 +02:00

Even Rouault	93f7f90711	opj_t1_decode_cblks(): tiny perf increase when loop unrolling	2016-05-23 11:53:53 +02:00
Even Rouault	1da397e94a	Tier 1 decoding: add a colflags array 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.	2016-05-23 11:53:53 +02:00
Even Rouault	31882ad7f4	Const'ify lut arrays so they are in the read-only data section	2016-05-22 00:54:06 +02:00

Even Rouault	23a01dfdef	Specialize decoding passes for 64x64 code blocks	2016-05-21 16:27:35 +02:00
Even Rouault	d8fef96f23	Improve code generation in opj_t1_dec_clnpass() 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.	2016-05-21 15:52:02 +02:00
Even Rouault	c539808d09	opj_t1_updateflags(): tiny optimization We can avoid using a loop-up table with some shift arithmetics.	2016-05-21 15:46:56 +02:00
