Static kCIImageApplyCleanAperture 

pub unsafe static kCIImageApplyCleanAperture: &'static CIImageOption

Available on crate feature CIImage only.

A Boolean value to control whether an image created with a CVPixelBuffer or an IOSurface should be cropped and offset according clean aperture attachments.

For a CVPixelBuffer this will use kCVImageBufferPreferredCleanApertureKey or kCVImageBufferCleanApertureKey.

If the value for this option is:

• True: then image will be cropped and offset to the clean aperture.
• False: then the full image is returned.
• CIVector : then use it as a CGRect to crop and offset.
• Not specified : then it will behave as if False was specified.
