# initWithWindow:rect:

Returns a cached image representation initialized for drawing in the specified window.

```
- (id) initWithWindow:(NSWindow *) win rect:(NSRect) rect;
```

## Parameters

`win`

The window (typically offscreen) in which the image is to be rendered. The window is retained by the receiver.

`rect`

The position and size of the image in the specified window. This rectangle should be specified in the base coordinate system of the window.

## Discussion

You must draw the image yourself in the designated part of the window. There are no `NSCachedImageRep` methods for this purpose.

## See Also

[`var size: NSSize`](/documentation/AppKit/NSImageRep/size)

The size of the image representation, measured in points in the user coordinate space.
