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.

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.

2020-06-23openjp2: Error out if failing to create Tier 1 handle.Sebastian Rasmussen
Previously when the handle failed to be created (e.g. when opj_calloc returned NULL due to low memory), the code still assumed that the t1 handle pointer was valid and dereferenced NULL, causing a crash. After this commit OpenJPEG will instead error out under this condition. This fixes issue #1255.
