Returns the current member of the set of rows returned by the iterator. 

This returns a pointer to an array of {\tt Byte}, with elements {\tt \mbox{[}0..W-1\mbox{]}} being guaranteed to be valid, where {\tt W} is the width of the bitmap. If the bitmap is uncropped, this is the total width of the bitmap as returned by method \hyperlink{classBitmap_a17}{get\-Width}; if cropped, the width is the difference of the \mbox{[}2\mbox{]} and \mbox{[}0\mbox{]} elements of the array returned by \hyperlink{classBitmap_a16}{bounding\-Box}.

Increments the iterator. 

If the bitmap is uncropped, all the rows in the bitmap will eventually be iterator over, namely the number of rows returned by method \hyperlink{classBitmap_a18}{get\-Height}; if it is cropped, the number of rows returned will be the difference between the \mbox{[}3\mbox{]} and \mbox{[}1\mbox{]} elements of the \hyperlink{classBitmap_a16}{bounding\-Box} array.
