# init(bitmapData:width:height:bytesPerRow:format:)

Creates a render destination based on a client-managed buffer.

## Declaration

```swift
init(bitmapData data: UnsafeMutableRawPointer, width: Int, height: Int, bytesPerRow: Int, format: CIFormat)
```

## Parameters

- `data`: Pointer to raw bits of a client-managed buffer that is at least (bytesPerRow * height) bytes in size.
- `width`: Width of the bitmap image in pixels.
- `height`: Height of the bitmap image in pixels.
- `bytesPerRow`: Number of bytes per row of data.
- `format`: Color format specifying how the colors are laid out in memory (for example, doc://com.apple.coreimage/documentation/CoreImage/CIFormat/RGBA8).

## Return Value

Return Value A CIRenderDestination object for rendering to a client-managed buffer.

## Discussion

Discussion The destination’s colorSpace property will default to a CGColorSpace created with sRGB, extendedSRGB, or genericGrayGamma2_2.
