Function Documentation

render() [1/2]

void cv::gapi::wip::draw::render	(	cv::Mat &	bgr,
		const Prims &	prims,
		const cv::gapi::GKernelPackage &	pkg = ocv::kernels()
	)

The function renders on the input image passed drawing primitivies.

Parameters

bgr	input image: 8-bit unsigned 3-channel image CV_8UC3.
prims	vector of drawing primitivies
pkg	contains render kernel implementation

render() [2/2]

void cv::gapi::wip::draw::render	(	cv::Mat &	y_plane,
		cv::Mat &	uv_plane,
		const Prims &	prims,
		const cv::gapi::GKernelPackage &	pkg = ocv::kernels()
	)

The function renders on two NV12 planes passed drawing primitivies.

Parameters

y_plane	input image: 8-bit unsigned 1-channel image CV_8UC1.
uv_plane	input image: 8-bit unsigned 2-channel image CV_8UC2.
prims	vector of drawing primitivies
pkg	contains render kernel implementation
