Dilate node¶
This documentation is for version 2.1 of Dilate (net.sf.cimg.CImgDilate).
Description¶
Dilate (or erode) input stream by a rectangular structuring element of specified size and Neumann boundary conditions (pixels out of the image get the value of the nearest pixel).
A negative size will perform an erosion instead of a dilation.
Different sizes can be given for the x and y axis.
Uses the ‘dilate’ and ‘erode’ functions from the CImg library.
CImg is a free, open-source library distributed under the CeCILL-C (close to the GNU LGPL) or CeCILL (compatible with the GNU GPL) licenses. It can be used in commercial applications (see http://cimg.eu).

Controls¶
Parameter / script name | Type | Default | Function |
---|---|---|---|
Size / size |
Integer | x: 1 y: 1 | Width/height of the rectangular structuring element is 2*size+1, in pixel units (>=0). |
Expand RoD / expandRoD |
Boolean | On | Expand the source region of definition by 2*size pixels if size is positive |
(Un)premult / premult |
Boolean | Off | Divide the image by the alpha channel before processing, and re-multiply it afterwards. Use if the input images are premultiplied. |
Invert Mask / maskInvert |
Boolean | Off | When checked, the effect is fully applied where the mask is 0. |
Mix / mix |
Double | 1 | Mix factor between the original and the transformed image. |
