Reader/writer for mac osx icon files.
|
|
3121
|
42 |
|
|
|
43 |
These files are actually bundles of a sequence of icons (in possibly different resolutions,
|
|
|
44 |
colors and sizes).
|
|
|
45 |
When such a file is read, I return the first image as usual,
|
|
|
46 |
and all images as an imagesequence.
|
|
|
47 |
|
|
3133
|
48 |
Only a subset of the supported image formats are supported by the writer
|
|
|
49 |
(i.e. JPEG and PNG based image encodings only).
|
|
|
50 |
This means, that only 10.8-and later icon files are really generated.
|
|
|
51 |
|
|
|
52 |
caveat:
|
|
3908
|
53 |
only a subset of the possibly formats are supported.
