Erode Dilate

Brief Description

Useful to shrink or extend the edges of a matte. Autograph offers 3 different algorithms which are useful in different scenarios:

• Morphological: Use a rectangular structuring element of specified size to perform a dilatation (if size > 0) or erosion (if size < 0)
• Blur Remap: Blur the image and then remap the values of the result, performing an operation that looks like a blur or dilatation
• Power-Weighted Blur: Uses a power-weighted filter to erode or dilate the image, which gives a smoother result than other approaches.

Controls

Parameter / Script Name	Type	Default	Function
Enabled / enabled	Boolean	On
Red / process_red	Boolean	On	Enable the red channel in output. Otherwise if there's a source the content of the main source is returned instead, else 0
Green / process_green	Boolean	On	Enable the green channel in output. Otherwise if there's a source the content of the main source is returned instead, else 0
Blue / process_blue	Boolean	On	Enable the blue channel in output. Otherwise if there's a source the content of the main source is returned instead, else 0
Alpha / process_alpha	Boolean	On	Enable the alpha channel in output. Otherwise if there's a source the content of the main source is returned instead, else 0
