The Minimum component replaces every pixel of the source image with the darkest color of its surrounding pixels within a certain radius, which has the effect of spreading out dark areas and shrinking bright areas.
This is a map component, it can be located in the Processing category on the Components Bar. Minimum is a bitmap-based component – in order to produce the output image, it renders a bitmap version of the source image. Using bitmap-based components in a filter can increase its rendering time, and, in some cases, degrade the quality of the final image, so Minimum should be used only when necessary.
Provides the source image. This is a required input – to make Minimum work, this input must be connected.
Adjusts the processing radius. Radius is measured as a percentage of the global Size value divided by 5. For example, if Size is set to 600 pixels, and Radius is set to 10, the actual radius will be 12 pixels.
When turned on, makes Minimum calculate four pixels and average them to produce the output pixel.
