The default value for the "compression" setting is "PackBits" which |
|
|
|
which is a widely supported RLE compression scheme for TIFF. The set of compression |
|
|
|
names to be used here matches the set that the Image I/O API uses. Note that |
|
|
|
not all compression schemes may be available during runtime. This depends on the |
|
|
|
actual codecs being available. Here is a list of possible values: |
