OpenCV4Android class Mat: difference between width() and rows(), and that between height() and cols()?

Question

In OpenCV4Android, what is the difference between the method width() and rows() ; and what is the difference between the methods height() and cols() of the class Mat ?

The documentation does not say anything about these methods.

Answer 1

There's no difference between them. In general width() == cols() and height() == rows() ;

In fact, the width() and height() methods internally calls the cols() and rows() methods to get the value.
