Rotation

Interpolation function

SYNOPSIS

#include "dip_interpolation.h"

dip_Error dip_Rotation ( in, out, angle, method, bgval )

DATA TYPES

binary, integer, float

FUNCTION

This function rotates an 2-D image in over angle to out using three skews. The function implements the rotation in the mathmetical sense, but note the Y-axis is positive downwards! The rotation is over the centre of the image.
