About the Equations filter

This filter allows you to apply a transform to a pixel layer using mathematical expression. You can achieve a number of distortion-type effects through the use of predetermined variables, trigonometry, exponentiation, etc. Additionally, you can use custom variables a, b and c in the equations and control their values through sliders on the filter dialog.

Settings

The following settings can be adjusted in the filter dialog:
