Initializer

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. You are responsible for releasing this object by calling CGImageRelease.
