2016-12-14Plug pixmap leak when fz_convert_pixmap() throws.Sebastian Rasmussen
2016-11-22Fix fz_warn() format compiler warning.Sebastian Rasmussen
2016-11-04Avoid warnings in 64bit windows builds of luratech bindings.Robin Watts
2016-11-02Explain conversion to RGB in jpx/jxr image loading.Sebastian Rasmussen
2016-10-13Bug 696885: Handle subsampled components in openjpeg decoder wrapper.Robin Watts
Also add simple ycc to rgb conversion (stolen from Sebastian's code).
2016-10-12Fix leak in fz_load_jpx_info.Robin Watts
2016-10-09Fix HAVE_JPEGXR and HAVE_LURATECH code for colorspace changes.Sebastian Rasmussen
2016-10-06Hide internals of fz_colorspaceRobin Watts
The implementation does not need to be in the public API.
2016-09-26Update OpenJPEG to the latest (git) version.Robin Watts
Part of the change in this code is to require opj_malloc and co. Sadly, opj_malloc and co do not take a context field, so a we need to wrap calls to openjpeg with a lock. I am reusing the freetype lock here for simplicity.

2016-06-17Use 'size_t' instead of int as appropriate.Robin Watts
This silences the many warnings we get when building for x64 in windows. This does not address any of the warnings we get in thirdparty libraries - in particular harfbuzz. These look (at a quick glance) harmless though.
2016-05-24Skip alphas for "loaded" JPXs (where possible).Robin Watts
2016-05-24fz_pixmap revamp: add stride and make alpha optionalRobin Watts
fz_pixmaps now have an explicit stride value. By default no change from before, but code all copes with extra gaps at the end of the line. The alpha data in fz_pixmaps is no longer compulsory. mudraw: use rgb not rgba (ppmraw), cmyk not cmyka (pkmraw). Update halftone code to not expect alpha plane. Update PNG writing to cope with alpha less input. Also hide repeated params within the png output context. ARM code needs updating.

2014-05-06Fix 694909: revert "Force colorspaces to match with JPX images." and ...Tor Andersson
... instead convert a JPEG2000 used as a soft mask into grayscale. This is more robust than trusting the PDF specified colorspace over the internal JPX colorspace. The spec implies that in a colorspace conflict, the internal JPX colorspace should be used. The PDF colorspace may be a DeviceN or Separation colorspace. DeviceN and Separation colorspaces are not valid destination colorspaces, so we may not always be able to convert the internal JPX colorspace into the PDF specified colorspace. Converting from the internal colorspace into grayscale is more robust, and solves the issue that the original commit was intended to fix.
