Problem of converting plots with both plotimage and multiplot to postscript [message #86069]

Hi all,

I was trying to plot some fits images using a combination plotimage.pro and multiplot.pro, it appears fine on my screen as well as output as PNG using write_png.pro. Below is what it look like when I export the plot as PNG:

But when I export it to PostScript, after conversion it appears to be something like this:

As you can see there's weird pixels plotted on my PS. I set it in IDL like this:

set_plot,'ps'
!p.font=0
device,filename= outfile,$
xsize= some number,$
ysize= some number,$
/encapsulate

multiplot,[0,3,6,0,0],xxxxxxx
....
plotimage, xxxx
....
multiplot,/reset

and of course, device,/close at the bottom.

It happens when I run my code on either my Linux machine or my Mac. I have never encountered such a problem when I plot postscript using plotimage nor multiplot before.

Thanks!
