CornerPin2D
Warps the image so the from1-4 corners land on to1-4.
Warps the image so the from1-4 corners land on to1-4. Drag the to handles in the Viewer. Use fewer corners (enable1-4) for a simpler move. Extra matrix, invert, filter, motion blur and bounding box work as on Transform, and it joins a Transform chain into one filter. Copy "from" to "to", Copy "to" to "from" and Set "to" to input are buttons.

Examples
Open these from Help › Examples…, or from the ? menu in this node's Properties panel.
- CornerPin a photo onto a plate (
examples/transform/cornerpin.oink): CornerPin maps the four corners of the source (from1-4) to four points (to1-4). The pinned photo is merged over another plate, like a screen replacement. - Tracker to CornerPin (
examples/transform/tracker_cornerpin.oink): Four points tracked on a moving plate, exported as an animated CornerPin that carries a text patch along with the move.
