If you’re a hacker who wants to help out Mozilla (and especially XULRunner), I’ve got a couple bugs that need owning: they both have to do with converting a cross-platform image format (probably PNG) into a platform-specific icon format.
- Bug 314651
- API to generate Mac .icns from a PNG image
- Bug 314030
- API to generate Windows icons from a PNG image
If you’re able and willing to help, please comment in the bug… I’ve got people who can help you with the Mozilla-API side of things such as getting image bit data from a PNG.
