Hi
1. What this purpose of the code? Perhaps you should use a TImageEnVect instead of a TImageEnView, then you can iterate through each of the rectange objects and remove them.
2. TCanvas.FrameRect uses the brush for the boundary not the Pen:

richedit1SelectionChange(Sender: TObject);
r1.io.bitmap.Canvas.Pen.Width := 5;
r1.io.bitmap.Canvas.Brush.Color := $007EEE;
r1.io.bitmap.Canvas.Pen.Style := pssolid;
r1.io.bitmap.Canvas.FrameRect(rc);

Sorry I may not be following, but if you have the original image, prior to your adding rects, why not just reload/assign it?
