Can you give some examples of the usage? (not the final product, but
the commands)
thanks
Sure... the usage is virtually identical to other drivers like the X or
PNG drivers.
For example, you may start GRASS with everyone's favorite South Dakotan
dataset, set up the environment and start a monitor. Then use the
standard GRASS drawing commands to draw, and finally close the monitor,
which will output the result to a file.
Here's a very simple example:
