Member Function Documentation

bool SkColorSpaceXform::apply	(	ColorFormat	dstFormat,
		void *	dst,
		ColorFormat	srcFormat,
		const void *	src,
		int	count,
		SkAlphaType	alphaType
	)		const

Apply the color conversion to a |src| buffer, storing the output in the |dst| buffer.

F16 and F32 are only supported when the color space is linear. This function will return false in unsupported cases.

Parameters

dst	Stored in the format described by \|dstColorFormat\|
src	Stored in the format described by \|srcColorFormat\|
len	Number of pixels in the buffers
dstColorFormat	Describes color format of \|dst\|
srcColorFormat	Describes color format of \|src\|
alphaType	Describes alpha properties of the \|dst\| (and \|src\|) kUnpremul preserves input alpha values kPremul performs a premultiplication and also preserves alpha values kOpaque optimization hint, \|dst\| alphas set to 1

static std::unique_ptr<SkColorSpaceXform> SkColorSpaceXform::New	(	SkColorSpace *	srcSpace,
		SkColorSpace *	dstSpace
	)

static

Create an object to handle color space conversions.

Parameters

srcSpace	The encoded color space.
dstSpace	The destination color space.
