# imageWithCGImage:scale:orientation:

Creates and returns an image object with the specified scale and orientation factors.

```
+ (UIImage *) imageWithCGImage:(CGImageRef) cgImage scale:(CGFloat) scale orientation:(UIImageOrientation) orientation;
```

## Parameters

`cgImage`

The Quartz image object.

`scale`

The scale factor to use when interpreting the image data. Specifying a scale factor of 1.0 results in an image whose size matches the pixel-based dimensions of the image. Applying a different scale factor changes the size of the image as reported by the [`size`](/documentation/UIKit/UIImage/size) property.

`orientation`

The orientation of the image data. You can use this parameter to specify any rotation factors applied to the image.

## Return Value

A new image object for the specified Quartz image, or `nil` if the method could not initialize the image from the specified image reference.

## Discussion

This method does not cache the image object. You can use the methods of the Core Graphics framework to create a Quartz image reference.
