# crop(at:destination:)

Crops the pixel buffer to a rectangle that’s defined by an origin and the destination buffer’s dimensions.

## Declaration

```swift
func crop(at origin: CGPoint, destination: vImage.PixelBuffer<Format>)
```

## Parameters

- `origin`: A point that specifies the origin of the image to keep.
- `destination`: The destination pixel buffer.

## Discussion

Discussion For example, the following code populates a pixel buffer from the center 3 x 3 pixels of a 5 x 5 planar buffer: let src = vImage.PixelBuffer<vImage.Planar8>(     pixelValues: [ 10, 11, 12, 13, 14,                    20, 21, 22, 23, 24,                    30, 31, 32, 33, 34,                    40, 41, 42, 43, 44,                    50, 51, 52, 53, 54 ],     size: vImage.Size(width: 5,                       height: 5))

let dest = vImage.PixelBuffer<vImage.Planar8>(     size: vImage.Size(width: 3,                       height: 3))

src.crop(at: CGPoint(x: 1, y: 1),          destination: dest)

// Prints: //  [ 21, 22, 23, //    31, 32, 33, //    41, 42, 43 ] print(dest.array)
