[Gnuplot-info] gnuplot output to jpeg/jpg format

[Zeray A. <zer...@ph...>]

Hi,
I would like to have the gnuplot outputs direct in jpeg or jpg formats.
I tried something like the following:
      set terminal <terminal_name>                                <--- eg
pbm
      set output "<output_filename>"                               <-- eg
"ztest.out"
                      ....
                load '<my_plot_command_file>'

Tried also Cygwin's tool:
   cjpeg ztest.out  > ztest.jpg
For this, I get the message:   ... not a ppm|pgm ...

Can anyone help here?
Any conversion tools for this?

Thanks,
Zeray
