| 2018-09-19 | Update to OpenJPEG 2.3.0. | Sebastian Rasmussen | |
| There is a regression for 2325_-_JPX_image_with_padding_rejected.pdf. Object 3 in that document is a JPX-encoded image. Its EOC marker is preceded by two extra bytes of data, 0x80 0x80. This makes the file broken according to the JPEG 2000 specification. Acrobat Reader and the Kakadu JPX decoder accepts this file without issues, so OpenJPEG 2.1.0 added code to fix this (bug 226, commit 005e75bdc). That fix detects exactly two bytes of 0x80 0x80, a rather brittle fix. Adding more padding or changing the padding byte values is not accepted. Adding more padding is acceptable to Acrobat Reader and Kakadu. An unrelated fix for another problem has since broken OpenJPEG's support for this broken image. | |||

| 2018-09-13 | Bug 699769: Fix bugs in upsampling code for JPX images. | Sebastian Rasmussen | |
| The upsampling code in the JPX decode attempted to guess a suitable upsampling factor. The guessed factor was wrong, causing writes of samples outside of the decoded image buffer. Simply limiting the coordinates to the image buffer would not suffice because the factor was wrong for every upsampled row of pixels. openjpeg does provide an upsampling factor, so use that instead and also take the component offsets into account when decoding components into the pixmap. Combined this resolves the issue that previously triggered ASAN. Thanks to oss-fuzz for reporting. | |||
| 2018-04-11 | Remove needless #defines in load-jpx.c | Tor Andersson | |
| 2018-02-01 | Drop JPEG/J2K/JPEG-XR/PNG/TIFF colorspaces even upon exception. | Sebastian Rasmussen | |
| For TIFF it was not just the colorspace, but other data as well. | |||
| 2018-01-04 | Bug 698836: Fix build with FZ_ENABLE_JPX=0. | Tor Andersson | |
| 2017-11-09 | Bug 698307: Improve stdint.h detection logic in openjpeg wrapper. | Robin Watts | |
| Thanks to Tamir Evan for this tweak. | |||
| 2017-11-09 | Bug 698353: Avoid having our API depend on DEBUG/NDEBUG. | Robin Watts | |
| Currently, our API uses static inlines for fz_lock and fz_unlock, the definitions for which depend on whether we build NDEBUG or not. This isn't ideal as it causes problems when people link a release binary with a debug lib (or vice versa). We really want to continue to use static inlines for the locking functions as used from MuPDF, as we hit them hard in the keep/drop functions. We therefore remove fz_lock/fz_unlock from the public API entirely. Accordingly, we move the fz_lock/fz_unlock static inlines into fitz-imp.h (an internal header), together with the fz_keep_.../fz_drop_... functions. We then have public fz_lock/fz_unlock functions for any external callers to use that are free of compilications. At the same time, to avoid another indirection, we change from holding the locking functions as a pointer to a struct to a struct itself. | |||
| 2017-11-01 | Use int64_t for public file API offsets. | Tor Andersson | |
| Don't mess with conditional compilation with LARGEFILE -- always expose 64-bit file offsets in our public API. | |||
| 2017-10-25 | Fix colorspace reference counting in fz_load_*_info. | Tor Andersson | |
| These are called from fz_new_image_from_buffer. | |||

| 2017-09-05 | Make luratech decoder glue compile after interface changes. | Sebastian Rasmussen | |
| 2017-07-19 | Add spots to fz_pixmaps. | Robin Watts | |
| Update separations interface further to cope with whether spots should be rendered separately, or as composite colors. | |||
| 2017-07-17 | Don't convert cmyka images to rgba | Michael Vrhel | |
| We should handle the cmyka images in their native form now that we are holding the data inverted. Fixes fts_17_1700.pdf Also fixes fts_43xx.xps | |||

| 2016-12-27 | Bug 697455: Make JPX support optional via configuration flag. | Tor Andersson | |
| Set FZ_ENABLE_JPX=0 in XCFLAGS or include/mupdf/fitz/config.h to disable support for JPX at compile time. Be aware that this may break support for PDF 1.5 and later files that need JPEG2000 support. | |||
