special: Literal PostScript
For simple graphics, or just for experimentation, literal PostScript
code can be included. Simply use a \special
beginning with a
double quote character `"'; there is no matching closing `"'.
For instance, the following (simple) graphic:
was created by typing:
\vbox to 100bp{\vss % a bp is the same as a PostScript unit \special{" newpath 0 0 moveto 100 100 lineto 394 0 lineto closepath gsave 0.8 setgray fill grestore stroke}}
You are responsible for leaving space for such literal graphics, as with
the \vbox
above.
