§ 12.11.18 - Local Contrast

Scripting command: loccontrast [Amount=0...100] [Density=0...9]

Note: All available scripting operations are listed on the Script operator page.

Modifies the local contrast of the selected region of an image.

Amount allows you to control the amount of effect applied.

 Density    should be adjusted to be larger for higher resolution images; that's not an exact guide, but it is a decent rule of thumb. What  Density    does is, as its value is increased, enlarges the number of pixels over which contrast changes are detected. Higher resolution images tend to take more pixels to accomplish such a change, hence a higher  Density    setting is needed to detect them.
