SpriteOutlineFx

SpriteOutlineFx is an image effect which adds outlines to sprites.

Usage

SpriteOutlineFx draws contour lines of alpha channel values. The following points should be kept in mind.

• The alpha channel of the screen must be cleared by setting a zero alpha color to the camera's clear color.
• Use a color mask to draw sprites/objects without outlines. See the Sprites-NoAlpha shader for a detailed usage example.
