Syntax

C++

Copy

public static void WarpPerspective(
	InputArray src,
	OutputArray dst,

Public Shared Sub WarpPerspective ( 
	src As InputArray,
	dst As OutputArray,

static member WarpPerspective : 
        src : InputArray *

(* Defaults:

-> unit

Parameters

src: Type: OpenCvSharp.CPlusPlusInputArray
input image.
dst: Type: OpenCvSharp.CPlusPlusOutputArray
output image that has the size dsize and the same type as src.
m: Type: OpenCvSharp.CPlusPlusInputArray
3x3 transformation matrix.
dsize: Type: OpenCvSharp.CPlusPlusSize
size of the output image.
flags (Optional): Type: OpenCvSharpInterpolation
combination of interpolation methods (INTER_LINEAR or INTER_NEAREST) and the optional flag WARP_INVERSE_MAP, that sets M as the inverse transformation (dst -> src).
borderMode (Optional): Type: OpenCvSharpBorderType
pixel extrapolation method (BORDER_CONSTANT or BORDER_REPLICATE).
borderValue (Optional): Type: SystemNullableScalar
value used in case of a constant border; by default, it equals 0.
