High resolution icon for file in Mac OS X?

Question

I am looking for a method similar to -[NSWorkspace iconForFile:] , but which returns the icon in higher resolution, if possible. In particular, I have an application that uses QuickLook to display file previews, and I would like it to return to the file icon if there is no smooth viewing of the plugin. However, using the iconForFile: method gives a small 32x32 icon. Is there a better way? One that returns NSImage or CGImageRef is preferred, but less accessible methods can also be great.

Answer 1

The returned image -[NSWorkspace iconForFile:] contains several views, including higher resolutions.

If you try to draw on 512x512, it will automatically select the appropriate view.

Answer 2

Here's how to make the icon bigger:

 NSImage * icon = [NSWorkspace iconForFile:yourPath]; [icon setSize:NSMakeSize(64,64)]; 

Here it is. Good luck
