Instance Method

append(_:)

Appends the specified matrix to the receiver’s matrix.

Declaration

macOS
func append(_ transform: AffineTransform)
Mac Catalyst
func append(_ transform: NSAffineTransform)

Parameters

aTransform

The matrix to append to the receiver.

Discussion

This method multiplies the receiver's matrix by the matrix in aTransform and replaces the receiver's matrix with the results. This type of operation is the same as applying the transformations in the receiver followed by the transformations in aTransform.
