Thank you and David.
In fact, I use coredraw to get tiff or jpg from PS. JPG is not good. The
tiff file is 7M, but the new PS file(only add a line on it) is 15M! So I ask
that.
Anyway, the method David told me is good.

IDL cannot read a PS file directly.
Convert the PS file to JPEG or TIFF using an external package like PhotoShop
or ImageMagick:
http://www.imagemagick.org/
and then import it into IDL using READ_JPEG or READ_TIFF.
Cheers,
Liam.

No, there is no READ_PS. Try something like Adobe Illustrator. :-)
Cheers,

That's good. Thank you.
The original figure is in PS form not JPG. But how to read PS figure to IDL,
I donot find: read_ps,'test.ps'??

With TVIMAGE you would do it like this:
p=[0.15, 0.15, 0.9, 0.9]
TVImage, a, Position=p
Plot, [0,1],[0,1],xrange=[0,1],yrange=[0,1],/nodata, $
/NoErase, Position=p
Oplot, x, y
With Liam Gumley's ImgDisp you just set the AXIS keyword,
I think.
You can find TVIMAGE here:

Cheers,
David
