Packit |
85355f |
The library is capable of dealing with images that are written to
|
|
Packit |
85355f |
follow the 5.0 or 6.0 TIFF spec. There is also considerable support
|
|
Packit |
85355f |
for some of the more esoteric portions of the 6.0 TIFF spec.

|
|
Packit |
85355f |
Both <tt>"MM"</tt> and <tt>"II"</tt> byte orders are handled.
|
|
Packit |
85355f |
Both packed and separated planar configuration of samples.
|
|
Packit |
85355f |
Any number of samples per pixel (memory permitting).
|
|
Packit |
85355f |
Any image width and height (memory permitting).
|
|
Packit |
85355f |
Multiple subfiles can be read and written.

|
Packit |
85355f |
Editing is not supported in that related subfiles (e.g.
|
|
Packit |
85355f |
a reduced resolution version of an image) are not automatically
|
|
Packit |
85355f |
updated.
