Function Documentation

app_init_img_mosaic()

vx_status app_init_img_mosaic	(	vx_context	context,
		ImgMosaicObj *	imgMosaicObj,
		char *	objName,
		vx_int32	bufq_depth
	)

Mosaic module init helper function.

This mosaic init helper function will create all the data objects required to create the mosaic node

Parameters

[in]	context	OpenVX context which must be created using vxCreateContext
[out]	imgMosaicObj	Mosaic Module object which gets populated with mosaic node data objects
[in]	objName	String of the name of this object
[in]	bufq_depth	Mosaic output buffer queue depth

app_deinit_img_mosaic()

void app_deinit_img_mosaic	(	ImgMosaicObj *	imgMosaicObj,
		vx_int32	bufq_depth
	)

Mosaic module deinit helper function.

This mosaic deinit helper function will release all the data objects created during the app_init_img_mosaic call

Parameters

[in,out]	imgMosaicObj	Mosaic Module object which contains mosaic node data objects which are released in this function
[in]	bufq_depth	Mosaic output buffer queue depth

app_delete_img_mosaic()

void app_delete_img_mosaic

(

ImgMosaicObj *

imgMosaicObj

)

Mosaic module delete helper function.

This mosaic delete helper function will delete the mosaic node that is created during the app_create_graph_img_mosaic call

Parameters

[in,out]

imgMosaicObj

Mosaic Module object which contains mosaic node objects which are released in this function

app_create_graph_img_mosaic()

vx_status app_create_graph_img_mosaic	(	vx_graph	graph,
		ImgMosaicObj *	imgMosaicObj,
		vx_image	background
	)

Mosaic module create helper function.

This mosaic create helper function will create the node using all the data objects created during the app_init_img_mosaic call.

Parameters

[in]	graph	OpenVX graph that has been created using vxCreateGraph and where the mosaic node is created
[in,out]	imgMosaicObj	Mosaic Module object which contains mosaic node which is created in this function
[in]	background	Background image provided in NV12 format will be used. If NULL, background will be black

writeMosaicOutput()

vx_status writeMosaicOutput	(	char *	file_name,
		vx_image	out_img
	)

Mosaic module write image helper function.

This mosaic helper function will write the contents of the provided image to the path provided in the file_name argument

Parameters

[in]	file_name	String of file path for where this output will be written
[in]	out_img	Output image to write to file
