# Creating a Core Graphics Image from a vImage Buffer

Create displayable representations of vImage buffers.

## Overview

Overview vImage provides a function for creating Core Graphics images from vImage buffers. This function allows you to display the results of a vImage operation to your user. Create the Image You create a Core Graphics image from the buffer, and initialize a UIImage instance from that. The createCGImage(format:flags:) function returns a CGImage instance based on the supplied Core Graphics image format (for more information, see Converting bitmap data between Core Graphics images and vImage buffers). The following example shows how to create a Core Graphics image from a vImage buffer: let result = try? destinationBuffer.createCGImage(format: format)

if let result = result {     // Assumes `imageView` is a `UIImageView`     imageView.image = UIImage(cgImage: result) }
