I am trying to run r.rescale to apply a contrast stretch to an image to
allow me to more easily locate ground control points using Georectify.
When I run the following command:
r.rescale input=Quickbird.blue at PERMANENT from=48,106
I get the following error:

Reclassify raster map based on category values.
Creates a new raster map whose category values are based
upon a reclassification of the categories in an existing
I would expect the reclass rules to be provided by r.rescale but maybe
I'm missing something. Is this a user problem or a bug?
