to prepare slides.

.SH MAKING SLIDES
\fBpl\fR and \fBpltab\fR may be used to create slides.
.LP
There are several strategies: 1) use \fBpl\fR or \fBpltab\fR in PostScript
mode, sending it directly to a film slide making system;
2) use \fBpl\fR or \fBpltab\fR to generate a data display then 
import it (PNG, EPS, GIF) into your slide system;
3) use \fBpl\fR or \fBpltab\fR in PNG or GIF mode and present 
graphs using a browser and a screen projection system.

.SH POWERPOINT
PNG and GIF files may be inserted as pictures with PowerPoint.
.LP
EPS files may be used with PowerPoint if the result will be
processed through a PostScript film imager (the EPS will not
be visible when previewing the slides on the screen, or if presenting
slides from a screen projector).  

.SH POSTSCRIPT
Ploticus will generate pagingated PostScript if the \fC-ps\fR command
line option is used; use \fC-eps\fR to get EPS output.
.LP
Most slide imaging devices accept PostScript input, either directly
or via a software driver.
The expected size, positioning, and orientation of the result
may vary.  
The above example creates PostScript that will work
with some slide imaging setups.  For others, the \fCproc page\fR
parameters may need to be adjusted for factors such as page size
and orientation.
.LP
Often light lines on a dark background works better on slides.
In the example, \fCproc page\fR is used to set a dark
background color (darkblue), and a light text/line color (white).
Also the overall line thickness is increased.

.SH TRANSPARENT BACKGROUND
It may be convenient to use a background color of \fCtransparent\fR when
making a PNG or GIF for inclusion into a slides package.  This allows
the ploticus graph to be "overlayed" on the existing background color
of the importing application (assuming that it knows about transparency).
