Gets a value that indicates whether this Matrix structure is an identity matrix.
Namespace: System.Windows.Media
Assembly: System.Windows (in System.Windows.dll)
Syntax
'Declaration
Public ReadOnly Property IsIdentity As Boolean
public bool IsIdentity { get; }
Property Value
Type: System.Boolean
true if the Matrix structure is an identity matrix; otherwise, false. The default is true.
Remarks
An identity matrix has a value of 1 in coefficients [1,1],[2,2],[3,3] and a value of 0 in the rest of the coefficients. This correlates to setting M11 and M22 to 1 and M12, M21, OffsetX, and OffsetY to 0. In an affine matrix, coefficients [3,1],[3,2],[3,3] are implied to always have the values 0,0,1 respectively.
