13.8. Recursive Transform
	13. Map Filters

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

Shear
Squares for scaling horizontally or vertically.

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

Figure 17.306. Changing perspective

Change perspective

The same pressing Ctrl

Figure 17.307. Scaling in all directions

Scaling

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.

13.8.2. Activate the filter

This filter is found in the image window menu under Filters → Map → Recursive Transform….

13.8.3. Options

Figure 17.308. “Recursive Transform” filter options

Presets, “Input Type”, Clipping, Blending Options, Preview, Split view

	Note
	These options are described in Section 2, “Common Features”.

First iteration

This option is used when the number of iterations has been set. Then the transformation starts at the position determined by this option.

Figure 17.309. “Recursive Transform” filter options

Original image. Iterations = 3. Fade = 0.797

First Iteration = 2

Iterations

Number of iterations.

Fade color

The color that will be used to fade. Default is transparency. You can change this color selecting a new color by clicking in the color swatch or using the color picker on the right.

Fade opacity

Amount by which to scale opacity of each iterated image.

Paste below

Paste iterated images below each other.

Resampling method

Interpolation methods are described in Interpolation

Three buttons

To add, duplicate or remove transform.

13.8.4. Using Recursive Transform Filter

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