Detailed Description

Utility class for generating signed distance field textures from anti-aliased alpha maps.

Although the generator can be used at run-time, the current version isn't convenient nor optimized for it.

Fill a texture with a signed distance field generated from the alpha channel of a source texture.

Parameters

source	Source texture. Alpha values of 1 are considered inside, values of 0 are considered outside, and any other values are considered to be on the edge. Must be readable.
destination	Destination texture. Must be the same size as the source texture. Must be readable. The texture change does not get applied automatically, you need to do that yourself.
maxInside	Maximum pixel distance measured inside the edge, resulting in an alpha value of 1. If set to or below 0, everything inside will have an alpha value of 1.
maxOutside	Maximum pixel distance measured outside the edge, resulting in an alpha value of 0. If set to or below 0, everything outside will have an alpha value of 0.
postProcessDistance	Pixel distance from the edge within which pixels will be post-processed using the edge gradient.
rgbMode	How to fill the destination texture's RGB channels.
