MatResize Method (Size, Double, Double, Interpolation)

OpenCvSharp Class Library

Resizes an image.

Namespace: OpenCvSharp.CPlusPlus
Assembly: OpenCvSharp.CPlusPlus (in OpenCvSharp.CPlusPlus.dll) Version: 1.0.0.0 (1.0.0.0)

Syntax

C++

Copy

public Mat Resize(
	Size dsize,
	double fx = 0,
	double fy = 0,
	Interpolation interpolation = Interpolation.Linear
)

Public Function Resize ( 
	dsize As Size,
	Optional fx As Double = 0,
	Optional fy As Double = 0,
	Optional interpolation As Interpolation = Interpolation.Linear
) As Mat

public:
Mat^ Resize(
	Size dsize, 
	double fx = 0, 
	double fy = 0, 
	Interpolation interpolation = Interpolation::Linear
)

member Resize : 
        dsize : Size * 
        ?fx : float * 
        ?fy : float * 
        ?interpolation : Interpolation 
(* Defaults:
        let _fx = defaultArg fx 0
        let _fy = defaultArg fy 0
        let _interpolation = defaultArg interpolation Interpolation.Linear
*)
-> Mat

Parameters

dsize: Type: OpenCvSharp.CPlusPlusSize
output image size; if it equals zero, it is computed as: dsize = Size(round(fx*src.cols), round(fy*src.rows)) Either dsize or both fx and fy must be non-zero.
fx (Optional): Type: SystemDouble
scale factor along the horizontal axis; when it equals 0, it is computed as: (double)dsize.width/src.cols
fy (Optional): Type: SystemDouble
scale factor along the vertical axis; when it equals 0, it is computed as: (double)dsize.height/src.rows
interpolation (Optional): Type: OpenCvSharpInterpolation
interpolation method

Return Value

Type: Mat
output image; it has the size dsize (when it is non-zero) or the size computed from src.size(), fx, and fy; the type of dst is the same as of src.
