Luisa, you can use module d.out.file (http://grass.gis-lab.info/grass64/manuals/html64_user/d.out.file.html) with the “resolution” parameter (double size or quadruple of the image).

I’m using r.out.png to generate PNG files from a small patch (like 6x15
pixels) but I’m obtaining a really small PNG file. Sicne I want to display
it a little bit bigger in a website I need to “create a bigger (in size)
PNG”. What can I do to do this?
One idea was to rescale it in a image processing software but I get a low
quality image
Is there any solution by using grass?
Thanks
Luisa

My friend, by your intention of helping Luisa, you ended up helping me a lot.
I guess I am so attached to the GRASS book that I was conformed to the fact that I could only export the active display monitor by using the PNG driver.
D.out.file will help me a lot. Thanks.
Marcello.
