| Rotate(nfloat, MatrixOrder) | |
| Rotate(CGAffineTransform, nfloat) |
Applies a rotation to the affine by the specified angle, in radians. |
| Rotate(nfloat) |
Applies a rotation to the affine by the specified angle, in radians. |
Rotate(nfloat, MatrixOrder)
public void Rotate (nfloat angle, CoreGraphics.MatrixOrder order);member this.Rotate : nfloat * CoreGraphics.MatrixOrder -> unitParameters
- angle
- nfloat
- order
- MatrixOrder
Applies to
Rotate(CGAffineTransform, nfloat)
Applies a rotation to the affine by the specified angle, in radians.
public static CoreGraphics.CGAffineTransform Rotate (CoreGraphics.CGAffineTransform transform, nfloat angle);static member Rotate : CoreGraphics.CGAffineTransform * nfloat -> CoreGraphics.CGAffineTransformParameters
- transform
- CGAffineTransform
The affine to rotate.
- angle
- nfloat
Angle represented in radians.
Returns
The rotated affine.
Remarks
This method is equivalent to the native CoreGraphics' CGAffineTransformRotate method.
Developers should note that this static method, M:CoreGraphics.CGAffineTransform.Rotate(CoreGraphics.CGAffineTransform,System.Single), left-multiplies transform by the rotation transformation that is defined by the angle. The multiplication order is, importantly, the reverse of what the developer expects from the instance method, M:CoreGraphics.CGAffineTransform.Rotate(System.Single).
Applies to
Rotate(nfloat)
Applies a rotation to the affine by the specified angle, in radians.
[Foundation.Advice("By default, the new operation is applied after the old operation: t' = t * [ cos(angle) sin(angle) -sin(angle) cos(angle) 0 0 ].\nTo have the same behavior as the native Swift API, pass 'MatrixOrder.Prepend' to 'Rotate (nfloat, MatrixOrder)'.")]
public void Rotate (nfloat angle);public void Rotate (nfloat angle);member this.Rotate : nfloat -> unitParameters
- angle
- nfloat
Angle represented in radians.
- Attributes
Remarks
Modifies the affine in place.
This method is not equivalent to the native CoreGraphics' CGAffineTransformRotate method (in which case use M:CoreGraphics.CGAffineTransform.Rotate(CoreGraphics.CGAffineTransform,System.Single) instead).
Developers should note that this instance method, M:CoreGraphics.CGAffineTransform.Rotate(System.Single), right-multiplies itself by the rotation transformation that is defined by the angle.
