12.4.2 Graphics

To draw a graphical shape, first specify a path and then fill and/or stroke the path with
appropriately configured fill and/or stroke colors. The functions that define these paths are
straightforward. For example, to draw a line, you position the cursor at the starting point of the
line using a call to pdf_moveto( ), then specify the path for this line with a call to pdf_lineto( ).
