SKMatrix Struct

Definition

A 3x3 transformation matrix with perspective.

public struct SKMatrix
public struct SKMatrix : IEquatable<SkiaSharp.SKMatrix>
Inheritance
SKMatrix
Implements

Remarks

It extends the traditional 2D affine transformation matrix with three perspective components that allow simple 3D effects to be created with it. Those components must be manually set by using the Persp0, Persp1, Persp2 fields of the matrix.

Constructors

SKMatrix(Single, Single, Single, Single, Single, Single, Single, Single, Single)

Creates a new instance of SKMatrix using the specified values.

SKMatrix(Single[])

Fields

Empty

Persp1

Gets or sets the y-perspective.

Persp2

Gets or sets the z-perspective.

ScaleX

Gets or sets the scaling in the x-direction.

ScaleY

Gets or sets the scaling in the y-direction.

SkewX

Gets or sets the skew in the x-direction.
