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

2019-04-15convertbmp: detect invalid file dimensions earlyYoung Xiao
width/length dimensions read from bmp headers are not necessarily valid. For instance they may have been maliciously set to very large values with the intention to cause DoS (large memory allocation, stack overflow). In these cases we want to detect the invalid size as early as possible. This commit introduces a counter which verifies that the number of written bytes corresponds to the advertized width/length.

2019-02-21openjp2/j2k: Report error if all wanted components are not decoded.Sebastian Rasmussen
Previously the caller had to check whether each component data had been decoded. This means duplicating the checking in every user of openjpeg which is unnecessary. If the caller wantes to decode all or a set of, or a specific component then openjpeg ought to error out if it was unable to do so. Fixes #1158.

jp3d/jpwl convert: fix write stack buffer overflow
2018-11-07jp2: convert: fix null pointer dereferenceHugo Lefeuvre
Tile components in a JP2 image might have null data pointer by defining a zero component size (for example using large horizontal or vertical sampling periods). This null data pointer leads to null image component data pointer, causing crash when dereferenced without != null check in imagetopnm. Add != null check. This commit addresses #1152 (CVE-2018-18088).

2018-10-31Fix some potential overflow issues (#1161)Stefan Weil
* Fix some potential overflow issues Put sizeof to the beginning of the multiplication to enforce that size_t instead of smaller integer types is used for the calculation. This fixes warnings from LGTM: Multiplication result may overflow 'unsigned int' before it is converted to 'unsigned long'. It also allows removing some type casts.
