init(jpegDataProviderSource:decode:shouldInterpolate:intent:)
Creates a bitmap image using JPEG-encoded data supplied by a data provider.
Declaration
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
A new CGImage. In Objective-C, you’re responsible for releasing this object by calling CGImageRelease.
