13.8. Recursive Transform

13.8.1. Overview

This filter applies a transformation recursively.

As in Unified Transform tool, this filter display a frame around the image with several kind of handles:

  • Diamonds for shearing


  • Squares for scaling horizontally or vertically.

    Scale horizontally

  • Small diamonds for changing perspective, in large squares for Scaling in all directions.

and outside the frame, the mouse pointer comes with a rotation icon: click-and-drag to rotate around the pivot. This pivot is, by default, at the center of the image: click-and-drag to move it.

13.8.4. Using Recursive Transform Filter

You can use this filter to create a Droste effect, 3D effects, trees.
