## Declaration

```swift
func pngData(actions: (UIGraphicsImageRendererContext) -> Void) -> Data
```

## Parameters

## Return Value

Return Value A Data object representing a PNG-encoded representation of the image created by the supplied drawing actions.

## Discussion

Discussion You provide a set of drawing instructions as the block argument to this method, and the method returns the resulting image as a PNG-encoded Data object. You can call this method repeatedly to create multiple images, each of which has identical dimensions and format.
