Hello,

Where can we find reference surrounding file types used by OS X (and others, as well)? For example, I would like to add the ability to save to icns format with a graphic manipulation tool I am working on.

It would also be helpful if anyone knows how to save to gif or jpeg since currently my app can only save to TIFF using the TIFFRepresentation to return the proper data to be saved.

Any help?

Thanks,
Jeff.

Well, I'm not sure exactly how you make a icns file, but I it looks like you can convert image types using NSBitmapImageRep's representationUsingType method. (I assume you're using Cocoa since you mentioned TIFFRepresentation.)

Oh, after a quick search, I see somebody's put together a class called IconFamily. Apparently creating icons is somehow a Carbon function that this wraps in a Cocoa class. You might want to take a look at that. Not as generally helpful as "File Types Around the World" or anything, but at least you should be able to figure out how to do what you want.

I was wondering if anyone knows how I could get an NSImage of the icon for a type of file, given the creator code and filetype? i.e. what is the icon for a file of creator 'MSIE' of type 'HTML'

I can get then finder's associated icon for an extension (e.g. foo.html) using [[NSWorkspace sharedWorkspace] iconForFileType:theExtension]

but this is not quite what I need. I note that the iconForFileType: method can also take an "encoded Filetype", but I can't seem to get this to return any image other than the 'blank document' icon.

Even if I could get this method to work with the filetype it seems inappropriate as there can be different icons for files with similar filetypes, but with different creators. (e.g. an OWEB HTML file has a different icon from an MSIE HTML file)?

Any clues?
