opj_encoder_set_extra_options(): add a GUARD_BITS=value option
...
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.

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 )
...
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 )
...
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.

API: deprecate 'bpp' member in favor of 'prec'
...
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.

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.
