An image with a selection
After “Distort”
The “Distort” command deforms the selection contour.
4.15.1. Activating the Command
You can access this command from the image menu bar through Select → Distort….
4.15.2. Description of the “Distort” Dialog Window
图 16.46. The “Distort” dialog
This command has several options which allow to increase or reduce the deformation. It is not possible to foresee the result and you have to experiment.
Threshold
A higher threshold shrinks the distorted selection. A lower threshold makes the selection bigger.
If the active selection has a regular shape (e.g. rectangle or ellipse selection), this option controls if the new outline is more inside the original selection or more outside the original selection.
Spread
A higher “Spread” increases the deformation.
Granularity
A higher “Granularity” increases the deformation.
Smooth
A higher “Smooth” decreases the deformation.
Deactivating Smooth horizontally or Smooth vertically increases the deformation.
