Oliver Tonnhofer	2af4026201	Improve encoding of TIFF tags (#3861) ... * Improve encoding of TIFF tags - Pass tagtype from v2 directory to libtiff encoder, instead of autodetecting type. - Use explicit types.

Requires type in v2 directory and values must be passed as a tuple. - Add support for signed types (e.g. TIFFTypes.TIFF_SIGNED_SHORT).

Konstantin Kopachev	e91b851fdc	Add reading old-JPEG compressed TIFFs ... Old-style JPEG compression in TIFFs are able to be read using Strip/Tile APIs. Although, it should be possible to read them using Scanline API, it does not work for some reason. Anyway, reading subsampled YCbCr formats through Strip/Tile/Scanline libtiff API does not de-subsample the data, so caller should unpack data to whatever format is appropriate. New-style JPEG compressed images were already read through libtiff as RGB images (https://github.com/python-pillow/Pillow/pull/3227). Unfortunately, there is no flag to ask libtiff to de-subsample old jpeg, but it provides a way to read any image as 32bit RGBA. This commit adds ability to read old-style JPEG TIFFs through reading *all* YCbCr images as RGBX using Tile and Strip reading API. This supersedes previous work (PR #3227) to read new-style JPEG-TIFFs.	2018-12-10 10:07:41 -08:00
