The definition of geom::min/max_row/col its that it gives you the image limits, so I should get lena's image in a chess pattern. Strangely as it may look, it happens to not fill the right and bottom edges as you can see in the picture:

I think there is something wrong in the tutorial as the loop should have as upper limit row/col *<=* geom::max_row/col instead of *=* Sorry for the late answer but thanks for your report!

Indeed, this is an obvious mistake... '=' should be replaced by '<=' in the loop as you noticed. It will be fixed in the next issue of the documentation. geom::max_{row,col}() functions returns the maximum {row,col} index which should be included in the browsing. Thanks again.
