| | | | | | | | | | | All recent versions of libtiff has support for the 64bit-indexed BigTIFF format. Allow reading it by recognizing its magic number.

* Extend support for tiled tiff files to all color formatsv5.9.0-beta3v5.9.0-beta2v5.9.0-beta1Eirik Aavitsland2017-03-1611-0/+0
| | | | | | | | | | | | | | | This commit extends the recently added support for tiled tiff images of color index format to also cover grayscale and mono images. RGB images were already covered, since the libtiff API used for those handles tiled images transparently. This commit also simplifies the tiff read() function by sharing common code among the different formats.

* Add support for tiled, color indexed tiff filesEirik Aavitsland2017-03-152-0/+0
| | | | | | | | | | | | For color index images, the tiff handler uses scanline based reading. The tiff decoder does not support that if the image is stored in tiled format. This commit adds tile based reading for such cases.
