Are you using today's software? This isn't the
page aspect problem we solved yesterday, is it?

And, I assume you are saying the PostScript file has
the text, but the PNG file does not. Is that correct?

Also, a couple of things about your code:

> nomatch,charsize=0.8
> !p.font=0 ;use postscript fonts
> !p.thick=3 ;data

> !y.thick=2 ;y axis

> color

There really is no reason to use PS_START if you are going to do
all of this. This is sort of the point of PS_START. It will set
all this stuff up for you.

If the only reason you are using PS_START and PS_END is to
produce a PNG file from the PS file, I'd just use the
ImageMagick convert command. So much simpler. :-)

I have a routine that just takes the name of a PostScript
file and creates a PNG file out of it. Takes about 15 seconds
to write.

Cheers,

David
