      This matrix. Useful for chaining method calls.

    • Decomposes the matrix into transform properties (x, y, scaleX, scaleY, and rotation). Note that these values may not match the transform properties you used to generate the matrix, though they will produce the same visual results.

      Parameters

      • Optionaltarget: DecomposedProps

        The object to apply the transform properties to. If null, then a new object will be returned.

      Returns DecomposedProps

      The target, or a new generic object with the transform properties applied.

    • Returns true if this matrix is equal to the specified matrix (all property values are equal).

      Parameters

      Returns boolean

    • Sets the properties of the matrix to those of an identity matrix (one that applies a null transformation).

      This matrix. Useful for chaining method calls.

    • Inverts the matrix, causing it to perform the opposite transformation.

      Returns IMatrix2D
