### 13.8. Recursive Transform

#### 13.8.1. 概観

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

  Shear

- Squares for scaling horizontally or vertically.

  Scale horizontally

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

  The same pressing Ctrl

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.
