It's worked great for me for every .icns icon so far except the ones in the SNOW.E aqua theme. Running "file" on them shows this:
Macintosh MacBinary data, type "Icon", creator "Mngl"
But trying to convert, I get this error:
Converting Finder to Finder.png...
Error loading icns resource!
Unable to find requested icon data!
Icon image is NULL!
Conversion of Finder failed!
Any idea what's wrong?
...forks.
I found the problem - it is with a 3 byte int (!!??) in the mac os resource maps.
I think this should fix the rest of the problems people are having, so I will release 0.5 non beta as soon as I figure out how to read the 3 byte int on x86.
On a side note, if people are willing to give a little in donations, I am now willing to open source GPL. Think of the possibilities... :D
I didn't expect a reply to that, honestly :)
Good to know the problem is at least tracked down; do you have an idea of when 0.5 might be ready? If icns2png can reliably convert all OSX icons, I think it would be worth the donation you ask for to get a KFile_ICNS plugin into KDE.
I wasn't really expecting a reply either... But then... I did get one :D
Thought the techies might like to know that stuff, but then, this isn't exactly a devel forum.
I am already planning a kfile plugin, and also want kview to support the format.
I need a bit of input from some kde development savvy people.
E-mail me: mathew%bearca!.com (Obvious changes to address)
Expect 0.5 within the week...

Thanks for the great program, but while using it I often get files that do not have the .png extension (e.g .pnQ is a rather common one). Also, I get a lot of segmentation faults, preventing the conversion of many icons.
I am thinking that these 2 problems might be related. They remind me of the (common) mistakes that people make when manipulating char arrays.
The names of the files I am converting are rather simple (e.g. heart_green).
Here's the output from my gdb session:

Thanks for your help.
Thanks for the gdb post... Good call on the filename char arrays.
It would technically die any time the new title was longer than the old one, since I allocated the old title's size for the new one.
This explains why some people thought you needed the .icns extension - It wouldn't segfault on the filenames.
I'll post a fixed version this afternoon.
icns2png: error while loading shared libraries: libstdc++.so.5: cannot open shared object file: No such file or directory
Reckon you could link a version with libc6?
Luke,
Sorry I took so long to respond.
Could you clue be in a bit more?... I thought I had linked it with libc6. ( I built it on a borrowed RH 8.0 system )

Let me know what to change for you.
How do you actually unstuff the .sit.hqx files? I have run unstuff twice, first on the .hqx and then on the .sit and just end up with some 0 byte files and sometimes a file of some kb that aren't icon files.
Any hint welcome.
Am I missing something? Is there a way to convert all the files in a directory at once? I tried normal wildcards, but it didn't work. Any help or ideas whould be greatly appreciated. TIA
ps. great prog. I've been wanting something like this for awhile.
I don't know the syntax of this program, but I assume it works like
icon2png mac.icn new.png
then type something like this on your friendly bash:
for i in (find . -name \*.icn); do
icon2png $i ${i%icn}png
done

Finally I can use this program on my Mandrake8.1... I love Mac icons. Great piece of software! Thank you for the source!
Perfect! Everything in SNOW.E converted fine :) This package really fills a need!

It is not parsing the resource maps on that icon set properly... I am looking into it.

Any chance you could tell me which filenames you're converting, and mabye post a gdb run?

When you unstuff, use unstiff -m=on
ok that was an unfortunate typo :)
a great work for a great program. fantastic work. thanks

Thanks I actually came up with almost the same thing on my own since my last post, but yours is a bit cleaner..... I'm still learnig shell scripting.
