ShellOut.py
call an external program passing the active layer as a temp file. Windows Only(?)
Author:
Rob Antonishen
Version:
0.7 fixed file save bug where all files were png regardless of extension
0.6 modified to allow for a returned layer that is a different size
than the saved layer for
0.5 file extension parameter in program list.
0.4 modified to support many optional programs.
this script is modelled after the mm extern LabCurves trace plugin
by Michael Munzert http://www.mm-log.com/lab-curves-gimp
and thanks to the folds at gimp-chat has grown a bit ;)
