Require `stdint.h` & `inttypes.h`

2023-09-24T11:54:28Z

With #1450 which goes with 480cc9d49775d018c19ce0e01f6be27858d63d39 "Remove support for non-C99 compilers (like VS2010) that don't support snprintf()", support for MSVC versions prior to vs2015 is dropped: https://stackoverflow.com/questions/2915672/snprintf-and-visual-studio-2010 This means that all supported MSVC versions do have `stdint.h` & `inttypes.h` now. For non windows platforms, those headers were already mandatory. Make them mandatory for all builds.

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.

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

2021-10-21T12:13:58Z

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

opj_decompress: add sanity checks to avoid segfault in case of decoding error

2020-04-01T19:11:36Z

Prevent crashes like: opj_decompress -i 0722_5-1_2019.jp2 -o out.ppm -r 4 -t 0 where 0722_5-1_2019.jp2 is https://drive.google.com/file/d/1ZxOUZg2-FKjYwa257VFLMpTXRWxEoP0a/view?usp=sharing

Fix some potential overflow issues (#1161)

2018-10-31T19:44:30Z

* 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.

tiftoimage(): fix read heap buffer overflow (#988)

2017-08-16T11:36:52Z

The number of components is given only by TIFFTAG_SAMPLESPERPIXEL / tiSpp. Querying TIFFTAG_EXTRASAMPLES only give information about which channel is the alpha channel, but we mostly ignore it for now, so remove that part of the code.
