This operation allows you to extract an arbitrary quadrilateral area out of the input image and stretch it to fill the full resolution of the output. It is the opposite of corner pin.
Four points are used to define the desired area of the input image. Image data outside the desired area is discarded.
This operation may be restricted to certain planes, or components of planes. In addition, the operation may be applied to a subset of frames within the sequence. An image must have both its frame and plane scoped to be modified.
Images that are not modified are passed through, which does not take any memory or processing time.
This operation may be masked, which restricts the operation to an area of the image. The mask may be inverted, brightened or dimmed.
The mask input is on the side of the node. The label on the connector indicates the plane being used as a mask.
The mask input can also be scaled to fit the output image’s resolution, if they differ. If this node is changing constantly, and the mask is not, it is somewhat faster to put a Scale COP down to do the resize for the mask image. Otherwise, the scale will occur every time this node cooks.
In the viewport:
click or press E (default hotkey) to edit the handles on the input image. The viewed image will change to that of the input.
Adjust the handles by dragging them to the corners of the area you wish to unpin.
You can Alt + click a handle to select it, or Alt + drag around handle to select them and move the selected handles as a group.Alt + click empty space to deselect the handles.
click again or press 'e' to return to viewing the output of this node.
Unpin will be temporarily bypassed while you select the input area. It will automatically un-bypass again when you finish selecting the area.
Specifies the units of the point coordinates.
