Question

Describe the question here

[ykwang]

I want to set a ROI in a image,and copy the other image into the ROI,
because seting the value one by one takes a long time.

Take a look at

opencv_dart/lib/src/core/mat.dart

Lines 1173 to 1175 in f9f934f

	void copyToWithMask(Mat dst, Mat mask) {
	cvRun(() => CFFI.Mat_CopyToWithMask(ref, dst.ref, mask.ref));
	}

But this API will be deprecated, use copyTo(Mat img, {Mat? mask}) in the future version
