What happens in TclTk is that the display output is set to a PPM file  
instead of monitor. Then any d.* command creates a graphic file. The  
display graphic file is then converted to a jpeg. The latter can be  
done by a variety of programs, including gdal-translate.

In wxPython, the display can be saved in a number of different formats  
using wxPython drivers.
