2022-02-10Add support for partial bitstream decoding (#1407) (fixes #715)Robert Gabriel Jakabosky
Add a -allow-partial option to opj_decompress utility and a opj_decoder_set_strict_mode() option to the API Co-authored-by: Chris Hafey <chafey@gmail.com>
2022-01-23opj_encoder_set_extra_options(): add a GUARD_BITS=value optionEven Rouault
and add a -GuardBits option to opj_compress. The recently-released SMPTE DCP Bv2.1 Application Profile (link below) says that the number of guard bits in the QCD marker shall be 1 for 2K content and 2 for 4K content. This change allows the number of guard bits to be configured, so that users of openjpeg have the control they need to meet the specification. https://ieeexplore.ieee.org/stamp/stamp.jsp?arnumber=9161348 This is an alternative implementation of https://github.com/uclouvain/openjpeg/pull/1388 that keeps ABI unchanged.

2022-01-15Added check for integer overflow in get_num_images (#1397)Eharve14
As discussed in pull request 1396, added a check for integer overflow. Change list: Defined num_images as unsigned int Moved the if statement to check for an empty directory to the beginning of the read directory section Added a check to see if num images would roll back to zero when incrementing.

2021-10-27opj_compress: add a -TargetBitDepth switch for TIFF output (#1384)msheby
Sometimes, given the same (16-bit TIF) input, one wants to generate a variety of J2C outputs (say, 16-, 12-, and 10-bit). This patch allows one to downsample input files, and so makes it easier to automate OpenJPEG in mass generation of J2Cs without having to pipe though an image processing program.
2021-10-21API: deprecate 'bpp' member in favor of 'prec'Even Rouault
in opj_image_comp and opj_image_comptparm structures. bpp was redundant with prec, and almost never set by the library, except by opj_image_create(). This change should hopefully not impact existing, working, users of the API, which should already have used prec to get things working. Fixes #1379

2021-09-25Added support for high throughput (HTJ2K) decoding.Aous Naman
There are a few limitations: - mixed mode (HT and regular code blocks) is not supported. - ROI in HT blocks is not supported. - Placeholder passes are not supported. - MultiHT sets are not support, only a singleHT set. - there are known issues with some compliance testing files related to the parsing of packet header.

2021-07-12opj_j2k_is_imf_compliant: Fix out of bounds access.Sebastian Rasmussen
Previously when mainlevel was parsed == 12 openjpeg would generate a warning, but then the sublevel value would be compared to an out of bounds element in the tabMaxSubLevelFromMainLevel array. From this commit OpenJPEG will only use mainlevel if in range.
