site_archiver@lists.apple.com Delivered-To: pro-apps-dev@lists.apple.com Martin, That's an interesting question. I'll assume you're drawing in canvas space (kFxDrawingCoordinates_CANVAS), since I think that's the only way you'll be able to draw where you want for this. (0, 0) is always the lower left corner. I don't think we have a way of getting the width and height of the canvas, though. I was thinking you might be able to convert from one space to another, but I don't think that works in this case. You may be constrained to the bottom and left edges. Please file a bug (or really enhancement request) on this. Darrin On Sep 14, 2011, at 8:41 AM, Martin Baker wrote:

We need to draw some buttons in the OSC similar to how FCPX's trim/crop/ken burns are shown.

How can we find out the width and height of the canvas to position the buttons in the top left of the canvas?
