This plug-in perform erosion or dilation of an image, by searching for maximum and minimum pixels in a radius.

Subpixel sampling is performed in high quality mode, allowing radius to be specified to 1/100th of a pixel.

Erosion or dilation can be performed on individual channels, in horizontal and vertical directions (resulting in blocky images). The radial direction setting results in circular glows.

8 and 16bit projects are supported by this plug-in.
