Provided Methods

unsafe fn imageForProposedSize_scaleFactor_imageOffset_imageSize( &self, proposed_size: CGSize, scale_factor: CGFloat, out_image_offset: NonNull<CGPoint>, out_image_size: NonNull<CGSize>, ) -> Option<Retained<CGImage>>

where Self: Sized + Message,

Available on crate feature objc2-core-graphics only.

Safety

• out_image_offset must be a valid pointer.
• out_image_size must be a valid pointer.
