Class NPPNativeMethods.NPPi.FilterGaussBorder

If any portion of the mask overlaps the source image boundary the requested border type operation is applied to all mask pixels which fall outside of the source image.

Currently only the NPP_BORDER_REPLICATE and NPP_BORDER_MIRROR border type operation is supported.

Filters the image using a Gaussian filter kernel:

1/16 2/16 1/16

2/16 4/16 2/16

1/16 2/16 1/16

or

2/571 7/571 12/571 7/571 2/571

7/571 31/571 52/571 31/571 7/571

12/571 52/571 127/571 52/571 12/571

7/571 31/571 52/571 31/571 7/571
