Question

Describe the question here

ykwang commented 4 months ago

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 https://github.com/rainyl/opencv_dart/blob/f9f934fa21329216e509216b9f7d43ea2016a73d/lib/src/core/mat.dart#L1173-L1175

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