Hi Martin

About that functionality. d.out.file allows me to define size of output 
image which is something that I need. WHen I try to do that with the 
functionality that you mention (e.g. with smaller H and W) I get the 
error I reported here 
Michael Barton suggested me to use this function.
I really need to produce output maps with a specific size and with 
image+scale bar. and when I set HxW I loose Scalebar in my output image.
