Re: How to convert PCL coordinates (x, y) to HPGL/2 coordinates (x, y) using HPGL/2 commands in PCL

The equivalent HP-GL/2 coordinate values will depend on a number of factors; for example:

• If you are using the default HP-GL/2 coordinate system, increasing values of the y-coordinate are in the opposite direction to the PCL coordinate, with the origin at the base of the specified PCL Picture Frame (whereas PCL y-coordinates start at the top of the page).
• But the HP-GL/2 coordinate system can also be set to match the PCL coordinate system, using the HP-GL/2 ROtate command.
• The HP-GL/2 units also need to be considered; absolute plotter units, or relative user units (as set via the HP-GL/2 SCale command).

See Part 2 of the PCL5 Technical Reference Manual http://h20000.www2.hp.com/bc/docs/support/SupportManual/bpl13211/bpl13211.pdf for more detail.
