I’m trying to find a good way to use a reference drawing. I have an original file (jpg, png) but when I bring it into Animation Paper it isn’t possible to size it to fit the HD frame. Drawing comes in very small and I cannot resize it. Lasso tool doesn’t work. Drawing won’t copy onto another frame.
You are right, you can not resize, draw or use the lasso tool on any reference. We are actually going to do a resizing mechanism, so in one of the next alpha releases you will be able to do exactly that.
For now, I suggest you fix your reference image elsewhere (photoshop or other image software you might have). So make it fill the HD frame as you want it, then save it as png and import it again into Animation Paper.
