# init(jpegDataProviderSource:decode:shouldInterpolate:intent:)

Creates a bitmap image using JPEG-encoded data supplied by a data provider.

## Declaration

```swift
init?(jpegDataProviderSource source: CGDataProvider, decode: UnsafePointer<CGFloat>?, shouldInterpolate: Bool, intent: CGColorRenderingIntent)
```

## Parameters

- `source`: A data provider supplying JPEG-encoded data.
- `decode`: The decode array for the image. Typically a decode array is unnecessary, and you should pass NULL.
- `shouldInterpolate`: A Boolean value that specifies whether interpolation should occur. The interpolation setting specifies whether a pixel-smoothing algorithm should be applied to the image.
- `intent`: A CGColorRenderingIntent constant that specifies how to handle colors that are not located within the gamut of the destination color space of a graphics context.

## Return Value

Return Value A new CGImage. In Objective-C, you’re responsible for releasing this object by calling CGImageRelease.
