Thanks Quincey - of course I can do exactly what you say - pick up the fact
that they are importing right at the start, ask them where they want the
converted file, put it there and open it. Simple and foolproof. Sometimes I

Hello,
If you are still learning I would recommend NSImage, it's the easiest to use.
If you need many images and high framerates I would recommend to use OpenGL.
CGImage, CIImage are rarely used for special purposes.. I wouldn't bother with
them at the beginning.

I have an NSImage. I want to save it with a CGImageDestination. the
CGImageDestination wants a resolution.
I know that the NSImage is resolution independent, but I happen to know that
this image has only one NSImageRep. I also know that the image is bitmapdata.
how do I get the resolution
If I have a class 'Foo' (containing the function 'Wabble'), which loads

control a view. This

This is a noob question, and as I pour through the docs, I thought I would

You shouldn't be relying on the color of a button to determine what to do next.
The color of the button should reflect some state that's maintained internally
by the controller, and you should rely on that state to determine what to do
next.
