public struct TransformMatrix : IEquatable<TransformMatrix>- Implements
Constructors
- TransformMatrix()
Initializes a new instance of the TransformMatrix class as the identity matrix.
- TransformMatrix(TransformMatrix)
Initializes a new instance of the TransformMatrix class using data from the specified matrix.
- TransformMatrix(double, double, double, double, double, double)
Initializes a new instance of the TransformMatrix class with the specified elements.
Fields
- DX
Get or sets the translation in the x-direction (the dx value, or the element in the third row and first column) of the matrix. This is the same as TransX.
- DY
Get or sets the translation in the y-direction (the dy value, or the element in the third row and second column) of the matrix. This is the same as TransY.
- M11
Gets or sets the scaling in the x-direction. This is the same as ScaleX. This is the value in the first row and first column of the matrix.
- M12
Gets or sets the skew in the y-direction. This is the value in the first row and second column of the matrix. This is the same as SkewY.
- M21
Gets or sets the skew in the x-direction. This is the value in the second row and first column of the matrix. This is the same as SkewX.
- M22
Gets or sets the scaling in the y-direction. This is the value in the second row and second column of the matrix. This is the same as ScaleY.
- ScaleX
Gets or sets the scaling in the x-direction. This is the same as M11. This is the value in the first row and first column of the matrix.
- ScaleY
Gets or sets the scaling in the y-direction. This is the same as M22. This is the value in the second row and second column in the matrix.
- SkewX
Gets or sets the skew in the x-direction. This is the same as M21. This is the value in the second row and first column in the matrix.
- SkewY
Gets or sets the skew in the y-direction. This is the value in the first row and second column in the matrix. This is the same as M12.
- TransX
Get or sets the translation in the x-direction. This is the same as DX. This is the value in the third row and first column in the matrix.
- TransY
Get or sets the translation in the y-direction. This is the same as DY. This is the value in the third row and second column in the matrix.
