Purpose: Demonstrate the drawing of a rectangular box. This example builds on the previous example by drawing a frame around the label. A 4” x 4” (288 points x 288 points) label is used in this example. The frame will be placed within 30 points of the edge of the label.
moveto - Position the drawing cursor at the desired location
This example assumes a 4” x 4” label (288 points x 288 points). A frame is drawn by moving to the starting point with the moveto operator.
lineto - Set the dimensions for the line
Forms three sides of the box with three separate lineto operators.
closepath - Close the shape
A box is drawn by drawing 3 sides of the box with the lineto operator followed by closepath, which closes the box by drawing the last line. It is important to use this operator to close a shape since the imaging algorithms may or may not actually close the shape due to rounding errors in the algorithm.
setlinewidth - Set the width of the lines
The width is set in points. In this example, the line width is set to 2 points. The this line width value will remain the effective value for all lines until changed.
