Luisa, you can use module d.out.file (<a href="http://grass.gis-lab.info/grass64/manuals/html64_user/d.out.file.html">http://grass.gis-lab.info/grass64/manuals/html64_user/d.out.file.html</a>) with the "<b>resolution</b>" parameter (double size or quadruple of the image).<br>

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