Custom Properties

The following table lists the custom properties that control the transform output.

Property	Type	Default	Description

offX	int	5	The number of pixels by which the shadow is offset from the visual object, along the x-axis. Positive integers move the shadow to the right, and negative integers move the shadow to the left.
offY	int	5	The number of pixels by which the shadow is offset from the visual object, along the y-axis. Positive integers move the shadow down, and negative integers move the shadow up.
