[PATCH v3 0/2] MR8006: windowscodecs/tests: Add some tests for multi-frame tiffs vs SUBFILETYPE tag.
Signed-off-by: Nikolay Sivov nsivov@codeweavers.com
-- v3: windowscodecs/tiff: Skip frames marked with SUBFILETYPE(0x1). windowscodecs/tests: Add some tests for multi-frame tiffs vs SUBFILETYPE tag.
From: Nikolay Sivov nsivov@codeweavers.com
This is important for RAW formats that use TIFF container, but mark directories as 'reduced-size'. Those files should be processed with appropriate RAW decoder, instead of displaying auxiliary frame with the TIFF decoder.
Unfortunately libtiff skips old tag OSUBFILETYPE == 0xff, it's not available via TIFFGetField() and SUBFILETYPE is not synthesized from it. On Windows both tags have the same effect on frames being skipped by the decoder.
