Why don't using Postscript Output?

old_dev=!D.name
SET_PLOT,'PS'

DEVICE,FILENAME='my_output.ps', PREVIEW=0,$
/COLOR, YOFFSET=27, YSIZE=16,XOFFSET=2,XSIZE=25,$
/LANDSCAPE

TEK_COLOR

x=INDGEN(37,/FLOAT)*10
y=SIN(x*!dtor)
PLOT,x,y,/nodata

OPLOT,x,y,linestyle=3,PSYM=-1,THICK=2,COLOR=2
DEVICE,/CLOSE
SET_PLOT,old_dev

If you then like to have an image you can use for example

pstoimg -type png -aaliastext -crop a -density 150 -flip r90
my_output.ps

display my_output.png

Comment from the help:
pstoimg - Convert a PostScript file to a bitmap image
using Ghostscript and the Netpbm utilities

The output as image has this way a much higher quality!
