If you display a graphic with GUIKit you can get coordinates back in
pixel coordinates - which may be what you want, although if the image is
scaled to fit the widget.....
I have been exploring ways to display 2-D Mathematica graphics objects
in GUIKit, and convert mouse click coordinates into Mathematica graphics
coordinates. I have a mechanism, which is incorporated in my
SuperWidgetPackage. This works well for me, but not for some others - so
there are obviously still some issues to be ironed out. Please look at
my website for more details, and maybe contact me directly.
