[GRASS-user] Question about "Generating PNG from display" functionality

Greetings

I want to generate a PNG from what is being displayed in Map Display Window (raster+vector+scale bar) but I want to generate a file in a specific size (HxW) that is different from the one that this tool suggests me. What happens is that the scale bar/north arrow is removed. but when I try with the size that the tool suggests me it is plotted with the scalebar/northarrow

Second question: can I generate this from command line?
Thanks
Antonio
