# NSCustomImageRep

An object that uses a delegate object to render an image from a custom format.

## Declaration

```swift
class NSCustomImageRep
```

## Overview

Overview When called upon to produce an image, an NSCustomImageRep sends a message to its delegate to do the actual drawing. You can use this class to support custom image formats without going to the trouble of subclassing NSImageRep directly.
