Available on crate features CIFilter and CIFilterBuiltins only.

The protocol for the Stretch Crop filter.

Distorts an image by stretching and or cropping to fit a target size.

Provided Methods

unsafe fn inputImage(&self) -> Option<Retained<CIImage>>

where Self: Sized + Message,

Available on crate feature CIImage only.

The image to use as an input for the effect.

unsafe fn setInputImage(&self, input_image: Option<&CIImage>)

where Self: Sized + Message,

Available on crate feature CIImage only.

Setter for inputImage.

unsafe fn size(&self) -> CGPoint

where Self: Sized + Message,

Available on crate feature objc2-core-foundation only.

The size in pixels of the output image.

unsafe fn setSize(&self, size: CGPoint)

where Self: Sized + Message,

Available on crate feature objc2-core-foundation only.

Setter for size.

unsafe fn cropAmount(&self) -> c_float

where Self: Sized + Message,

Determines if and how much cropping should be used to achieve the target size. If value is 0 then only stretching is used. If 1 then only cropping is used.

unsafe fn setCropAmount(&self, crop_amount: c_float)

where Self: Sized + Message,

Setter for cropAmount.

unsafe fn centerStretchAmount(&self) -> c_float

where Self: Sized + Message,

Determine how much the center of the image is stretched if stretching is used. If value is 0 then the center of the image maintains the original aspect ratio. If 1 then the image is stretched uniformly.

unsafe fn setCenterStretchAmount(&self, center_stretch_amount: c_float)

where Self: Sized + Message,

Setter for centerStretchAmount.
