Fixed filters perform linear filtering operations (such as convolutions) with predefined kernels of fixed sizes.
Note that this section also contains a few dynamic kernel filters, namely GaussAdvanced and Bilateral.
Some of the fixed filters have versions with border control. For these functions, 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 border type operation is supported for these functions.
