Applies a dilate filter to the image. This can be useful for expanding mask.
Container for user-defined plugs. Nodes should never make their own plugs here, so users are free to do as they wish.
The output image generated by this node.
Turns the node on and off.
The input image
The size of the filter in pixels. This can be varied independently in the x and y directions.
The method used when the filter references pixels outside the input data window.
Expands the data window to include the external pixels which the filter radius covers.
If specified, this channel will be used to compute the pixel index to select for all channels. You would probably want to use this with a channel that represents the overall luminance of the image. It will produce a rank filter which is lower quality, but preserves additivity between channels, and is a bit faster.
