rmoveto

rmoveto is a command used in certain graphics and drawing contexts, particularly within PostScript and related page description languages. It functions as a relative moveto command. Unlike a standard moveto command, which specifies an absolute position on the page, rmoveto establishes a new current point based on the previous current point. The coordinates provided to rmoveto are interpreted as offsets from the current position. For instance, if the current point is (100, 200) and rmoveto is called with arguments (50, 25), the new current point will be (100 + 50, 200 + 25), which is (150, 225). This relative positioning is useful for drawing sequences of points or shapes where each new element's position is defined in relation to the one that preceded it, simplifying complex path construction. It's a fundamental building block for defining paths and graphics elements in a programmatic way.
