Description

Hi,

I tried to use getRectSubPix to extract something from my image but it seems getRectSubPix is nowhere to be found. Is that function not yet implemented to opencv4nodejs or it won't be implemented at all?

And is there any alternative for doing the exact same thing as getRectSubPix?

Thanks in advance. 🥂
