Hello,

Sorry if the question has been asked already, but i'm not sure of the simple answer : how to determine the cv::Mat data field size ?

I've read this page : link text

So rows*step is enough, no need to take care of elemSize or depth ?

Thanx a lot :)

The simplest way I know is:

int bytes = Mat.total() * Mat.elemSize();

The Mat.total() returns rows x cols and Mat.elemSize() returns channels x sizeof(type)

ok, thanx :)
