TIFF 6.0 Specification Coverage
|
|
Packit Service |
2594b8 |
|
|
Packit Service |
2594b8 |
The library is capable of dealing with images that are written to
|
|
Packit Service |
2594b8 |
follow the 5.0 or 6.0 TIFF spec. There is also considerable support
|
|
Packit Service |
2594b8 |
for some of the more esoteric portions of the 6.0 TIFF spec.

in the 6.0 specification; the JPEG support is based on the post-6.0
