MJW Posted December 20, 2015 Share Posted December 20, 2015 (edited) I believed it was okay to do all the rendering in OnSetRenderInfo; however, when I wrote a plugin that does that, it worked fine with rectangular selections, but when I tried a circular selection, it wrote outside the selected area. Red ochre asked about the same problem in a earlier thread, and was advised to use a per-pixel selectionRegion.IsVisible test. I don't mind testing IsVisible (though I've read in the past that it's slow), but I want to make sure writing to the dst surface in OnSetRenderInfo is allowed, and not just something that happens to work as long as IsVisible is tested.
