#4 png2icns does not write large icons properly

[Andrea Musuruane]

I'm the Fedora project maintainer for icns2png/libicns.

Someone has opened the following bug report in our bugzilla.

Description of problem:
I created an ICNS file from 16x16, 32x32, 48x48, 128x128, 256x256, and
512x512 4-channel PNGs using png2icns. On Mac OS X, the 256x256 and 512x512
sizes are present but unreadable in the ICNS file. As a result, Mac OS X
scales up smaller icons are scaled up for these two sizes, and apparently that
causes transparency to be lost, which looks terrible and makes ICNS files
produced this way unusable.
[...]

A more detailed description is available here:

libicns is built against jasper-devel and libpng-devel in Fedora.

Hi,

Several bugs were fixed with png2icns since 0.6.0 and 0.6.1 - can you have your user try those versions?

Thank you,

Hi Mathew, we ship v0.6.1 in Fedora.

Bug caused primarily by a lack of cdef block in generated jp2 icon. Manually generated cdef block added to code fixed the unreadable icns. Fix is in SVN.

Also appears to want some icons in sorted order. Need to maintain icns elements in sorted order as elements are added and removed. Fix not yet completed.

The bug should be fixed as of release 0.6.2
