Hi,

I am using polyfill to plot radar scans directly to postscript. The
resulting files are quite big (~1MB) and I need to make them smaller.Is
there a simple way?

I thought about using the z-buffer to do the plotting then saving it to
postscript like this

loadct,13
!P.MULTI=[0,2,1]
set_plot,'Z'
erase,255
device,set_font='Helvetica',/TT_FONT
device,z_buffering=0

......call to plotting routines (plot,polyfill)

a=tvrd(true=3)
close

set_plot,'ps'
device,/helvetica,/color,bits=8,/encapsulated,xsize=14.8,ysi ze=10.5
device,filename='test.eps'
tv,a,true=3
device,/close

!P.MULTI=0

....the resulting colors are all messed up.

Thanks in advance

Isa
