2017-08-07Tidy fx_codec_jpx_opj.cppchromium/3180Tom Sepez
Single no-op callback. pdfium::clamp() where appropriate. Use post-increment where appropriate. Add helper functions for image type.

2017-08-07Fix PartitionAlloc vs. opj_malloc mismatch in fx_codec_jpx_opj.cppTom Sepez
Apply patch suggestions from reporter. Move all FX_Alloc'd memory into unique_ptrs so that no bare FX_Alloc/Free_Free calls remain. Fix a realloc / opj_realloc mismatch. Remove unused functions color_apply_icc_profile() and color_apply_conversion(). Tidy along the way, add some missing statics, and fix a confusing (but not quite member shadowing) local name.

2017-06-30Use the right free function for ICC color profiles.chromium/3146Chris Palmer
They are allocated with |opj_malloc| (which is just |malloc|), but we were freeing them with |FX_Free|. But |FX_Free| recently changed to be |PartitionFree|. This is probably not the right ultimate fix, but it should solve the high-occurence crash we're seeing in the short term.

2017-06-08Guard against undefined shifting in JPX decoderDan Sinclair
If the prec value in syncc444_to_rgb is more then 30 then when we shift left we'll go negative. The subsequent -1 will cause an overflow. This CL early returns if the prec value is > 30.

2016-09-12Verify value of prec before usingdsinclair
The fx_codec_jpx_opj code will attempt to do a 1 << (prec - 1). If the prec value is >=32 then that shift will overflow the int value. This CL adds a check that prec is < 32 before attempting the shift. BUG=chromium:633208 Review-Url: https://codereview.chromium.org/2334823002
