I do not want to change the dockTile, and no public method of NSDockTile appears to change the dock icon in any case. I am indeed using -[NSApplication setApplicationIconImage:], my problem is creating a new image that has the correct areas transparent.
What is the Cocoa way to alter an NSImage dynamically (or perhaps alter a copy of an original image), at run-time, while preserving as transparent any transparent areas it may have to begin with?

And play around with Photoshop a bit; the Quartz > model is quite similar. I am sure I can do it; it's all just ones and zeros and I have access to all the bits. But I am not a graphics specialist and I am reluctant to become one. (And I have never used Photoshop or anything remotely like it.) I am just looking for a way to alter images dynamically, at run-time, that is as easy as putting up an offscreen window/view hierarchy and drawing into it. I would like to be able to use something like the capabilities of NSView for superimposing different things on my new image. I would like to work the problem at as high a level as I can. In a separate comment, Scott Ribe has pointed out that I can draw to an image directly by instantiating it and locking focus. He is right, I did not read Sherm's suggestion carefully. However, I was doing my drawing in a view/window hierarchy in order to make it easy to superimpose a badge-like string on my image (I just put an NSText on top of the view that contains the image and write the string with a background of appropriate color.) I need to thank you all for being patient with someone who is unfamiliar with low-level Macintosh graphics; I need all the help I can get. --Kyle Sluder -- Jay Reynolds Freeman --------------------- jay_reynolds_free...@mac.com http://web.mac.com/jay_reynolds_freeman (personal web site) _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
