[Opengrads-users] how to manipulate the grads internal pictures directly?

[Qian H. <yor...@gm...>]

Hi everyone,
I am currently developing a GUI program to show meteorological fields. My
solution is wxpython＋pygrads. I am planning  to use pygrads to generate
 pictures, and then load the pictures into the GUI using wxpython. I think
this isn't the best solution, and wondering is there anyway to manipulate
the gards internal picture objects directly, so i don't need to save the
pictures with commands like printim first.
Thanks!
