opj_encoder_set_extra_options(): add a GUARD_BITS=value option

2022-01-23T16:54:44Z

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.

Added check for integer overflow in get_num_images (#1397)

2022-01-15T14:33:03Z

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.

opj_compress: add a -TargetBitDepth switch for TIFF output (#1384)

2021-10-27T12:10:50Z

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.
