"Bare bones" Imageview component for lazarus
« on: September 21, 2010, 01:17:03 pm »
A simple viewer that derives from TScrollingWinControl and thus uses no extra components for it's scrollbars. I havent implemented scaling and zoom yet, but I will port it over from my Delphi components together with the ruler code. Depending on the speed I may also get the editor classes over, but that would require access to the raw pixelbuffer.

Put the initial source up here:

If you do implement zoom in/out, it would be very helpful if you would expose the scale factors for reading so that applications using the component can determine the relative size of the view.
