## Detailed Description

## Enumeration Type Documentation

## § NppStBorderType

enum NppStBorderType

Border type

Filtering operations assume that each pixel has a neighborhood of pixels. The following structure describes possible ways to define non-existent pixels.

Enumerator
nppStBorderNone | There is no need to define additional pixels, image is extended already.
nppStBorderClamp | Clamp out of range position to borders.
nppStBorderWrap | Wrap out of range position. Image becomes periodic.
nppStBorderMirror | reflect out of range position across borders

## § NppStInterpMode

enum NppStInterpMode

Filter types for image resizing

Enumerator
nppStSupersample | Supersampling. For downscaling only.
nppStBicubic | Bicubic convolution filter, a = -0.5 (cubic Hermite spline)
