Thanks people !
I'm agree with david about the keyword names and method
descriptions... But don't worry.
I could use the PS_START/PS_END routines with ImageMagick but the
problem is that if somebody wants to run my application, install the
ImageMagick and configurate it will be required. I don't like this
option.
I'll try to use the gmwindow and modify it.
Thanks !
B.

Perhaps you could have a keyword to set user expectations
appropriately. Something like this:
IDL> MyPlot, data, /HIGH_QUALITY_RENDERING
It would not only take him a long time to type, but
it would be put it in his mind that it will take a
long time to render, too. :-)
Cheers,
David

Yes, it wouldn't surprise me if it was faster to use
the PS_START/PS_END with Direct Graphics approach and
just display the resulting PNG file produced from
ImageMagick than it would be to draw all those objects!
Cheers,
David
P.S. I notice R, which is similar in a *lot* of ways to
IDL, doesn't have any problem with nice looking fonts in
its plots. :-)

Here's a routine to produce better looking direct graphics using the
same technique. You can produce a plot like this:
http://hrscview.fu-berlin.de/mex4/software/gmwindow/gmwindow .png
using a syntax very close to the usual:
w=obj_new("gmwindow",title="gmwindow")
w->plot,indgen(20),findgen(20)^2,psym=-5,ytitle="an axis
title",background=200,color=0,charsize=2
w->oplot,indgen(20),400-findgen(20)^2,psym=-4,color=128
w->xyouts,10,200,"a label",color=0,charsize=3
http://hrscview.fu-berlin.de/mex4/software/gmwindow/gmwindow __define.pro
regards,
Greg

Perhaps you have to set up your Z-buffer more carefully - things like
pixel depth, etc.

I tried this solution for my code and it doesn't works.
I've different colors and plots, oplots, etc..
I don't know, maybe the problem is the !P struct..
If I use object graphics to have nice looking fonts, the problem is
the quantity of the objects I've. The Draw method is so slow for
draw more than 15000 graphic objects (the result when I converted
each plot writted in direct graphics to object graphics)

"Direct Graphics" and "Nice Fonts" are two terms that should not be used in
the same sentence. :-) Seriously David's solution is as godd as it gets, so
use it...
