Thanks for the code. My only concern is about the performance hit
from copying into an array and converting to and from PNG format. It
should be possible to get the pixel data directly from your
System.Drawing.Image (using lockBits), use that to initialise an
NSBitmapRep, and create the NSImage from that.
But from everybody's responses, the impression I get is that MonoMac
doesn't have any built-in support for getting System.Drawing content
into a Cocoa view, so we have to come up with our own workarounds.
Nobody knows anything about the "drawing bridge" mentioned in
Tarkvara Design Inc.
