RPG — Return to Previous Graphics state
Format
RPG;
Parameter
None
Function
The RPG command restores the graphics state most recently saved by a SCG (Save
Current Graphics) command. The following items of graphics state revert to the state
saved previously.
• Path and cursor position (if defined)
• Pen diameter (line width)
• Line join type
• Line cap type
• Miter limit
• Dash pattern
• Flatness
• Fill pattern (16
× 16 dots)
• Clipping rectangle
• Raster resolution
• Image model
It is useful to save the graphics state then later restore it when you want to use a path for
both stroking and filling. One such example is shown below.
The RPG command does not affect other printing system parameters such as page
orientation, unit of measurement, etc. (See RES on page 220.)
