Presently, following devices are currently supported by g2: +X11, GIF, PostScript (xfig and Win32 are in developement). + +One major feature of the g2_library is the concept of virtual +devices. An arbitrary number of physical devices (such as GIF, or X11) +can be grouped to create a so-called virtual device. Commands sent to +such a virtual devices will automatically issued to all attached +physical devices. This allows for example simultaneous output to a GIF +file and a Postscript file. A virtual device in turn can be attached +to another virtual device, allowing to construct trees of devices. +Virtual devices can also be useful when using different +user-coordinate systems. E.g. one X11 window showing an overview of a +graphical output, and a second window showing a zoom of a more +detailed area of the graphic. Drawing in both windows is performed by +one single command to the virtual device. |
