CAD drawing Filling Holes 5   This functionality is available only in the Raster module.

The filter fills small holes in raster objects. In this case, only those “holes” are filled, the size of which is less than the specified value. This filter can automatically estimate the size of holes in image objects.

The filter can be used after binarization or separation procedures to fill in unwanted holes in raster objects.
