§ 16.21 - Bend

Quick Reference to Scripting Command
a=BEND(amount, base, WRAP, ALPHA)
Items in CAPS are 0/1 or ranges with more options than just 0/1.
Ranges other than 0/1 are indicated by brackets, such as [0-2].

Unmodified Image

Bend of .7 with Bottom Base and Wrap on

This operator may be applied directly to a Warp Layer, resulting in a geometric effect that may be removed from the underlying sublayer composite by simply zeroing out the warp or disabling that layer. In addition, the effect may be moved over the underlying sublayer composite without limit.

A visual reminder that this operator is warp-compatible is the small green dot at the upper right of its ICON in the toolbar.

§ 16.21.1 - Bend Controls

§ - Bend Amount

This is a floating point number where 1.0 represents the exact width or height of the image, which one depending on the base.

§ - Base of Bend

This sets the side of the image that the bend emits from; the image is bent away from this side.

§ - Wrap

This tells the operator if pixels that move off on one edge should be wrapped back into the image past the opposing edge.

§ - Insert Alpha

If Wrap is off, then the question arises: What to do with the region that the image data has moved away from? You can either leave it the same as it was, or you can make it transparent. That's what the Insert Alpha checkmark causes to happen.
