I am trying to create a book cover by using PSTricks. I follow the source from here :http://tug.org/pracjourn/2007-1/robbers/robbers.pdf (page 22). When I compile, it annouces the error that :

! Undefined control sequence.
 \c@lor@to@ps 

l.29 ...tyle=solid,fillcolor=Maroon](0,0)(13.24,9)

The control sequence at the end of the top line
of your error message was never \def'ed. If you have
misspelled it (e.g., `\hobx'), type `I' and the correct
spelling (e.g., `I\hbox'). Otherwise just continue,
and I'll forget about whatever was undefined.

And the error is in fact at the line :

\psframe[fillstyle=solid,fillcolor=Maroon](0,0)(13.24,9)

Please tell me what I should do? Thanks in advance.

    You're probably using pstricks with pdflatex. – egreg Feb 6 '13 at 9:50
  • See <recently read> \c@lor@to@ps or Error with pstree. Please tell us if the answers there helped, we should close this as a duplicate. – Stefan Kottwitz Feb 6 '13 at 10:15
  • Yes, thanks. I have changed and it does not annouce the error there any more. However, it now annouced the error at the box \sbox\IBox{\includegraphics[height=9in]{grass3.jpg}}. It said that "Cannot determine size of graphic in grass3.jpg". How I can correct it then? Thanks a lot. – 9999 Feb 6 '13 at 12:51
