Function Documentation

function CGAffineTransformInvert ( aTransform  )

Inverts a transform.

Parameters
aTransformthe transform to invert
Returns
CGAffineTransform an inverted transform CGAffineTransform

Definition at line 99 of file CGAffineTransform.j.

function CGAffineTransformMakeRotation ( anAngle  )

Returns a transform that rotates a coordinate system.

Parameters
anAnglethe 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
aTransformthe transform to rotate
anAnglethe amount to rotate in radians
Returns
void CGAffineTransform

Definition at line 78 of file CGAffineTransform.j.

function CGRectApplyAffineTransform ( aRect  ,
anAffineTransform

Parameters
aRectthe rectangle to transform
anAffineTransformthe transform to apply
Returns
CGRect the new transformed rectangle CGAffineTransform

Definition at line 121 of file CGAffineTransform.j.

function CPStringFromCGAffineTransform ( anAffineTransform  )

Creates and returns a string representation of an affine transform.

Parameters
anAffineTransformthe transform to represent as a string
Returns
CPString a string describing the transform CGAffineTransform
