then calculate the offset, and then control the read and write to the pixel, we are lazy here, with the array way of access, in fact, and the starting address plus offset is the same ha.It can be found that we did not use data[i*img->widthstep+j] = 0;, but instead used Cv_image_elem (IMG, unsigned char, I, j) = 0; Cv_image_elem is a macro, it helps us to encapsulate the next, it is very simple to use, so it is used, its definition in the types_c.h inside, its macro definition is as follows:
