Function Documentation

int shbeu_blend	(	SHBEU *	beu,
		const struct shbeu_surface *	src1,
		const struct shbeu_surface *	src2,
		const struct shbeu_surface *	src3,
		const struct shbeu_surface *	dest
	)

Perform a surface blend.

See shbeu_start_blend for parameter definitions.

void shbeu_close

(

SHBEU *

beu

)

Close a BEU device.

Parameters:

beu

BEU handle

SHBEU* shbeu_open

(

void

)

Open a BEU device.

Return values:

0

Failure, otherwise BEU handle

int shbeu_start_blend	(	SHBEU *	beu,
		const struct shbeu_surface *	src1,
		const struct shbeu_surface *	src2,
		const struct shbeu_surface *	src3,
		const struct shbeu_surface *	dest
	)

Start a surface blend.

Parameters:

	beu	BEU handle
	src1	Parent surface. The output will be this size.
	src2	Overlay surface. Can be NULL, if no overlay required.
	src3	Overlay surface. Can be NULL, if no overlay required.
	dest	Output surface.

Return values:

	0	Success
	-1	Error

void shbeu_wait

(

SHBEU *

beu

)

Wait for a BEU operation to complete.

The operation is started by a call to shbeu_start_blend.

Parameters:

beu

BEU handle
