Yeah i executed that node successfully but when i try to replace that circle drawing code with other codes available in opencv docs like rgb to grey converter, i get some errors and cannot compile

Is it about the number of channels? I have a feeling that it is RGBA2GRAY (or even BGRA2GRAY; OpneCV is loading the image automatically in BGR format)...

Anyway, you shall add the error lines for getting more help
