Other tricksBefore discussing some other techniques, we must take a closer look at theway POSTSCRIPT handles graphics. When we give instructions to draw apath in POSTSCRIPT, it is not immediately drawn; we will also have to giveinstructions to draw it, or stroke it in POSTSCRIPT terminology. Again, we willhave to give explicit commands to fill a region. The command \pscustomautomatically does the stroking and filling at the end, subject to the variouslinestyle and fillstyle options. But within \pscustom we ourselves canstroke or fill using the commands \stroke or \fill. We can also use thecommand \newpath to clear the current path and current point.
