Function Documentation

function CGAffineTransformInvert ( aTransform )

Inverts a transform.

Parameters:

aTransform the transform to invert

Definition at line 99 of file CGAffineTransform.j.

function CGAffineTransformMakeRotation ( anAngle )

Returns a transform that rotates a coordinate system.

Parameters:

anAngle the amount in radians for the transform to rotate a coordinate system

Returns:: CGAffineTransform the transform with a specified rotation CGAffineTransform

Definition at line 63 of file CGAffineTransform.j.

function CGAffineTransformRotate	(	aTransform	,
		anAngle
	)

Rotates a transform.

Parameters:

aTransform	the transform to rotate
anAngle	the amount to rotate in radians

Definition at line 78 of file CGAffineTransform.j.

function CGRectApplyAffineTransform	(	aRect	,
		anAffineTransform
	)

Applies a transform to the rectangle's points. The transformed rectangle will be the smallest box that contains the transformed points.

Parameters:

aRect	the rectangle to transform
anAffineTransform	the transform to apply
