Converting Grass raster to GIF or TIFF

Good Morning ,

Is there anyway in Grass4.1 to convert a Grass raster file into a GIF or
TIFF file?

I'm having problems displaying a raster of CHINA as I don't know the correct
row*col values for the r.support files. Is there a way of finding these
quickly without having to try the combinations suggested by r.support ?

Thank you

Jeremy
