Member Function Documentation

static sp<ScriptIntrinsicLUT> android::RSC::ScriptIntrinsicLUT::create	(	sp< RS >	rs,
		sp< const Element >	e
	)		[static]

Supported elements types are U8_4.

The defaults tables are identity.

Parameters:

[in]	rs	The RenderScript context
[in]	e	Element type for intputs and outputs

Returns:

ScriptIntrinsicLUT

void android::RSC::ScriptIntrinsicLUT::forEach	(	sp< Allocation >	ain,
		sp< Allocation >	aout
	)

Invoke the kernel and apply the lookup to each cell of ain and copy to aout.

Parameters:

[in]	ain	Input allocation
[in]	aout	Output allocation

void android::RSC::ScriptIntrinsicLUT::setAlpha	(	unsigned char	base,
		unsigned int	length,
		unsigned char *	lutValues
	)

Sets entries in LUT for the alpha channel.

Parameters:

[in]	base	base of region to update
[in]	length	length of region to update
[in]	lutValues	LUT values to use

void android::RSC::ScriptIntrinsicLUT::setBlue	(	unsigned char	base,
		unsigned int	length,
		unsigned char *	lutValues
	)

Sets entries in LUT for the blue channel.

Parameters:

[in]	base	base of region to update
[in]	length	length of region to update
[in]	lutValues	LUT values to use

void android::RSC::ScriptIntrinsicLUT::setGreen	(	unsigned char	base,
		unsigned int	length,
		unsigned char *	lutValues
	)

Sets entries in LUT for the green channel.

Parameters:

[in]	base	base of region to update
[in]	length	length of region to update
[in]	lutValues	LUT values to use

void android::RSC::ScriptIntrinsicLUT::setRed	(	unsigned char	base,
		unsigned int	length,
		unsigned char *	lutValues
	)

Sets entries in LUT for the red channel.

Parameters:

[in]	base	base of region to update
[in]	length	length of region to update
[in]	lutValues	LUT values to use
