set imprun
set imprun script-name
This command sets up automatic execution of a grads script before
every display
command.
grads version 2.1 introduced the use of the Cairo library to handle all the graphics rendering, both for the interactive display in X windows and for the hardcopy and image outputs. The addition of Cairo means that grads can support drawing a wide variety of fonts, smoother looking anti-aliased lines, transparent colors, pattern filling, and more options for graphical output formats. These features provide an opportunity to create some beautifully polished publication-quality graphics.
