# Cropping and working with regions of interest Crop images and apply operations to regions of interest. ## Topics ### Cropping [`func crop(at: CGPoint, destination: vImage.PixelBuffer)`](/documentation/Accelerate/vImage/PixelBuffer/crop(at:destination:)) Crops the pixel buffer to a rectangle that’s defined by an origin and the destination buffer’s dimensions. [`func cropped(to: CGRect) -> vImage.PixelBuffer`](/documentation/Accelerate/vImage/PixelBuffer/cropped(to:)) Returns a new pixel buffer that contains a copy of the data specified as a subregion of an existing pixel buffer. ### Region of Interest [`func withUnsafeRegionOfInterest(CGRect, (vImage.PixelBuffer) throws -> R) rethrows -> R`](/documentation/Accelerate/vImage/PixelBuffer/withUnsafeRegionOfInterest(_:_:)) Calls the given closure with a pixel buffer that references the image data within the specified region of interest. --- Copyright © 2026 Apple Inc.
