I suggest to leave it up to the application that uses gimp-print then. Any application that uses units in it's user interface will have a framework to deal with units. If you add your own framework to gimp-print you are only making things more complex. > 2) The dimension type tells the user interface to treat this > parameter specially (display it in units of the user's choice). Any length parameter in GIMP is measured in pixels and if there's resolution information, the user is given the opportunity to use arbitrary units to specify it. The underlying code still sees nothing but pixels. I don't see why the underlying code (in this case gimp-print) would have to know about this. Sven
