Composite with Polygon Mask
Posted: December 2nd, 2021, 4:25 pm
Latest version.
Compositing with a Polygon Mask, if (to keep the explanation easy) I have a rectangular mask shape, I can move any side (by clicking and dragging an outside boundary line) vertically or horizontally without changing the other three sides (their points do not move), except of course, the adjacent sides lengthen.
However, if one side is not perpendicular to the adjacent sides, and I drag the opposite side to enlarge/reduce the shape, the point which is the shortest distance from the side being dragged "follows" the drag direction. The point which is the farthest from the side being dragged, as expected, does not move.
For example, a rectangular Polygon, if the lower left point is moved up (so the bottom side is angled), and the upper side is dragged either up or down, the noted point moves up or down as well, while the lower right point remains fixed.
Looked in the Help file for clarification, but could not find anything, so am wondering if this is working as intended?
