Patch Editor Basics
Last Updated on
Patch nodes (or Patches) such as Rectangle, Bezier Warp, Quad Warp, and others (see the full list of patch nodes) are designed to apply various types of image* geometry correction (warping), transformation, arrangement, and mapping. Extensive control for patch management is provided in the Patch Editor integrated into the Canvas (or Render Target) widget.** In addition, most operations with the patches can be performed directly from a computer keyboard connected to the Server.
*The term “image” refers to any static or dynamic media (i.e. video).
**To access the Patch Editor, add the Canvas (or Render Target) widget to your workspace, then click the Patches tab on the top left of the widget to switch to the Patches view.
