I have everything you need for that in the "NSImage (PalmExtensions)" category, part of my osx-palm-tools project (BSD licensed). Here is the URL for the source code:

http://cvs.sourceforge.net/viewcvs.py/osx-palm-tools/PalmServices/
(get the NSImage-PalmExtensions.{h,m} files)

Specifically, you'll want to do:

NSRect r = [myImage rect];
Rect bounds = {0, 0, r.size.height, r.size.width};

PicHandle pictDataH = [myImage PICTHandle];

CGrafPtr oldPort;
GDHandle oldGD;
GetGWorld(&oldPort, &oldGD);
LockPixels(GetGWorldPixMap(myGWorld));
SetGWorld(myGWorld, NULL);
DrawPicture(pictDataH, &bounds);
SetGWorld(oldPort, oldGD);
UnlockPixels(GetGWorldPixMap(myGWorld));

I guess that given the number of requests for that kind of stuff I see in the forum, I should make the image manipulation code a generic category and put it in a separate place on the web...

Hope this helps,
Florent

Any suggestions on how best to do this? Specifically we are trying to draw a EPS image into a CGrafPort. We don't care how we get it in there, but ultimately it must end up in a CGrafPort.

I see that the Web Kit has a ConvertNSImageToCGImageRef() or some such routine, but it requires having Safari installed...a requirement we may not be able to make.
