I use IDL, but everything should be the same in PV-Wave.
When printed to a PostScript file, encapsulated or not, IDL always uses the
same size plot area. When you use the command TV the way you do, you're
telling IDL to put the image in the lower left corner of this plot area. It
does expand the size of the image to fill as much of the available space as it
can (but only for PostScript output).
To center the image, use the optional X and Y parameters to the TV (or TVSCL)
command. With PostScript output, I also prefer to include the XSIZE and YSIZE
keywords to give me complete control over the size of the displayed image.
These parameters can be given in device, normalized, or data coordinates
(assuming that the data coordinate system has been defined), or on PostScript
devices they can also be given in inches or centimeters.
I do have software that will automatically scale the image to the plot area,
and center it, regardless of the graphics device. This software is available
via anonymous ftp from
idlastro.gsfc.nasa.gov (128.183.57.82)
in the directories
contrib/thompson
contrib/thompson/standalone
Good luck,
Bill Thompson
