TImageEnProc.Closing

Declaration

procedure Closing(WindowSize: Integer);

Description

Perform a dilation (Maximum filter with WindowSize parameter) followed by an erosion (Minimum filter with WindowSize parameter).

The closing filter operation will reduce small negative oriented regions and negative noise regions.

Note:
◼A UI for this is available to your users in the Image Processing dialog
◼If the image PixelFormat is not ie24RGB or ie1g, it will be converted
