Creating an Icon

I’d like to have an icon on my MainW. If I drag a photo or a screen shot into an image well and/or a canvas, the scale of
what I have dragged is totally out of whack. How do I change the scale of what I have dragged?

If it’s the icon of the application, you can use NSImage constants to get the system to draw it for you. The MacOSLib, MBS Plugin or the Retina Kit has code for this, at whatever size you want.

Thanks for help. I got it!
