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

    Shear

  • 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.

13.8.2. Activate the filter

This filter is found in the image window menu under FiltersMapRecursive Transform….

„Recursive Transform“ filter options

Presets, Input Type, Clipping, Blending Options, Preview, Split view
[Poznámka] Poznámka

These options are described in 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.

„Recursive Transform“ filter options

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 Cubic (sometimes called Bicubic): The color of each pixel is computed as the average color of the eight closest pixels in the original image. This usually gives the best result, but it naturally takes more time.

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.
