*This documentation is for version 1.0 of Morphology (net.fxarena.openfx.Morphology).*

Description
-----------

Morphology modifies an image in various ways based on the nearby neighbourhood of the other pixels that surround it. This in turn can provide a huge range of effects, Shape expansion and contraction (dilate/erode), to distance from edge, to thining down to a skeleton, or mid-line axis.
