* tiff: Return proper error for missing LZMA compressionDiego Elio Pettenò2014-08-18
| | | | | | | | The LZMA support is a semi-official extension supported by libtiff 4.0.0 and later. Signed-off-by: Diego Elio Pettenò <flameeyes@flameeyes.eu> Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* tiff: Improve grayscale supportDiego Elio Pettenò2014-08-10
| | | | | | | | | | Only use PAL8 if palette is present, else use GRAY8 for pixfmt. Instead of simulating a grayscale palette, use real grayscale pixels, if no palette is actually defined. Signed-off-by: Diego Elio Pettenò <flameeyes@flameeyes.eu> Signed-off-by: Luca Barbato <lu_zero@gentoo.org>

* Revert "tiff: support reading gray+alpha at 8 bits"Janne Grunau2014-07-21
| | | | | This reverts commit b31d76e45fc3c6529dd7109e721676f3ec376d00 as it uses an unkown pixel format.

* tiff: use a better name and enum values for PhotometricInterpretationJustin Ruggles2014-04-12
| | | | Also add additional known values and log as missing features.
* tiffdec: use a single strip if RowsPerStrip is 0Justin Ruggles2014-04-12
| | | | | The spec does not specify that 0 is an error condition, and there are samples which use 0 when the whole image is in one strip.

| | | | | | Based on a patch by Paul B Mahol <onemda@gmail.com> CC:libav-stable@libav.org

* tiff: set palette in the context when specified in TIFF_PAL tagStefano Sabatini2011-05-24
| | | | | | | | | | | Since image initialization was moved after tag parsing, the palette needs to be specified in the context and then copied to the allocated image in init_image(). Fixes a regression with TIFF images that have palette data, trac issue #230, file Test_Flate_8bpp.tif. Signed-off-by: Diego Biurrun <diego@biurrun.de>
* tiff: add support for SamplesPerPixel tag in tiff_decode_tag()Stefano Sabatini2011-05-12
| | | | | | | | | | | | | Format detection and internal frame initialization is moved to a separate init_image() function, which is called when all the tags have been read, and so both BitsPerSample and SamplesPerPixel information has been collected. This fixes decoding of the file 11.tiff from roundup issue #1925. Based on a patch by Kostya Shishkov <kostya.shishkov@gmail.com>. Signed-off-by: Diego Biurrun <diego@biurrun.de>
