Represents a 2D rotation and uniform scale matrix.
public struct SKRotationScaleMatrix : IEquatable<SkiaSharp.SKRotationScaleMatrix>- Inheritance
-
SKRotationScaleMatrix
- Implements
Remarks
This struct stores rotation as scaled cosine/sine values (SCos and SSin) and translation (TX and TY). Use ToMatrix() to convert to a full SKMatrix.
Constructors
| Name | Description |
|---|---|
| SKRotationScaleMatrix(Single, Single, Single, Single) |
Creates a new SKRotationScaleMatrix with the specified components. |
Fields
| Name | Description |
|---|---|
| Empty |
Represents an empty matrix with all components set to zero. |
| Identity |
Represents the identity matrix (scale of 1, no rotation, no translation). |
Properties
| Name | Description |
|---|---|
| SCos |
Gets or sets the scaled cosine component (scale * cos(angle)). |
| SSin |
Gets or sets the scaled sine component (scale * sin(angle)). |
| TX |
Gets or sets the x-axis translation component. |
| TY |
Gets or sets the y-axis translation component. |
Methods
| Name | Description |
|---|---|
| Create(Single, Single, Single, Single, Single, Single) |
Creates a rotation-scale matrix with the specified scale, rotation (in radians), translation, and anchor point. |
| CreateDegrees(Single, Single, Single, Single, Single, Single) |
Creates a rotation-scale matrix with the specified scale, rotation (in degrees), translation, and anchor point. |
| CreateIdentity() |
Creates an identity matrix that represents no transformation. |
| CreateRotation(Single, Single, Single) |
Creates a rotation matrix with the specified angle (in radians) around an anchor point. |
| CreateRotationDegrees(Single, Single, Single) |
Creates a rotation matrix with the specified angle (in degrees) around an anchor point. |
| CreateScale(Single) |
Creates a uniform scale matrix with no rotation or translation. |
| CreateTranslation(Single, Single) |
Creates a translation matrix with no rotation or scale. |
| Equals(Object) |
Determines whether the specified object is equal to the current instance. |
| Equals(SKRotationScaleMatrix) |
Determines whether the specified SKRotationScaleMatrix is equal to the current instance. |
| GetHashCode() |
Returns the hash code for this instance. |
| ToMatrix() |
Converts this rotation-scale matrix to a full 3x3 transformation matrix. |
Operators
| Name | Description |
|---|---|
| Equality(SKRotationScaleMatrix, SKRotationScaleMatrix) |
Determines whether two SKRotationScaleMatrix instances are equal. |
| Inequality(SKRotationScaleMatrix, SKRotationScaleMatrix) |
Determines whether two SKRotationScaleMatrix instances are not equal. |
