Does anyone know of a way to increase the spatial resolution of the
plots in Maple??
Ultimately I want to create images that can be saved in a standard
image file format (e.g. jpeg), but one doesn't seem to be able to
specify the size of the output... I would like to tell Maple to
generate a plot that is say 12000 pixels by 1600 pixels.
If Maple isn't currently able to do this, it would be a wonderful
feature in a future version. One could use Maple to create
mathematical art!!
Thanks,

I give you an answer that I got from customer support some time ago
for the case of .gif file.
The resolution of a gif image can be enhanced by specifying its height
and width in plotoptions. For instance, say you want to print a gif
image which is to fill an 8.5 x 11 in landscape, with 1 inch margins,
at 600 dpi. Then, you would want to set the height to 3900 (=6.5*600)
and the width to 5400 (=9*600). That is:
> restart:
>
plotsetup(gif,plotoutput="rayout.gif",plotoptions="height=3900,width=5400");
> plot(sin(x),x=0..2*Pi,color=black,resolution=600);
The size of this file is an acceptable 352 kB. Unfortunately though,
the export to gif has no control over the font, causing the axes
labels to be very small, yet still readible. Make sure that when you
print the image you choose 'fit to page' or something along those
lines.
I hope you find this an improvement.
If you have any further questions or comments, please do not hesitate
to contact us.

This might help for the .jpeg file as well....I am not sure.

If you use "plotsetup" or "interface" to produce the jpeg plot, you can
specify its height and width in pixels. See the help page ?plot,device.
However, 12000 by 1600 may be a bit too much (when I tried it, although
Maple didn't complain my web browser refused to display the resulting
file, so I don't know if the problem is in Maple or Netscape). 1000 by
1000 worked fine, though. This was in Release 5.1 on a Sun; the help
page claims that 480 x 360 is approximately the maximum size available
on 32-bit platforms, but that seems not to be the case.
