Then I zapped different parts of the a rose sprite to create the skeletal image on the right. Spoke Inversion works best on circular sections of sprites. If you check out the quick look at the GIF Animator page , the Vortex, Mesa and Spoke Inversion effects can be applied to create some bizarre animations. We already explored the process of using a shape or another sprite as a template for brush shapes. Another way to customize the size of a brush is to define one using the New Brush button in the Paint Palette.
Larger values create bigger brushes.
The Aspect spin box sets the shape of your custom brush. An Aspect of 100 is a circular brush. Lower values create increasingly flat oval shapes. The Rotation spin box adjusts the angle of rotation of the brush you are designing. Rotation only works if you set an Aspect less than 100.
