h2. Description

PostScript plotting, settings and commands. 

The plotting system in Geocap called dplot is applying these commands to plot maps with a high carthographic standard. 

PostScript is a state system which means that a specific setting is valid until a new setting is applied.

Note that it is possible to use *psc com* to write native PostScript commands. Check the [PostScript Language Reference Manual (third edition)|http://www.adobe.com/products/postscript/pdfs/PLRM.pdf].

{indent}
{info:title=Scale to match width of window/viewport} 
*hor*: scale_y = scale_x. 
*ver*: scale_x = scale_y. 
*inside*: shortest of scale_x or scale_y.
