TIFF 6.0 Specification Coverage
The library is capable of dealing with images that are written to follow the 5.0 or 6.0 TIFF spec. There is also considerable support for some of the more esoteric portions of the 6.0 TIFF spec.

| Core requirements |
Both "MM" and "II" byte orders are handled. Both packed and separated planar configuration of samples. Any number of samples per pixel (memory permitting). Any image width and height (memory permitting). Multiple subfiles can be read and written. Editing is not supported in that related subfiles (e.g. a reduced resolution version of an image) are not automatically updated. Tags handled: ExtraSamples, ImageWidth, ImageLength, NewSubfileType, ResolutionUnit. Rowsperstrip, StripOffsets, StripByteCounts, XResolution, YResolution |
