[GRASS-user] How to crop away NODATA margins

[Hermann Peifer]

Hi,

I see that d.out.file has a switch: -m  (Do NOT crop away margins). So I assume 
that by default, white margins are auto-cropped.

What I am  looking for is some sort of auto-crop feature which I could use with 
r.out.gdal, in order to get rid of abundant NODATA margins in raster layers.

What I am currently doing: I identify a raster layer's data extent visually 
before changing the region and then running r.out.gdal. However, I might miss 
some islands at the edges...

Thanks in advance, Hermann

g.region zoom=myrast align=myrast


I overlooked this in the documentation, I have to admit :-(

Sorry for the noise and thanks to both of you. Hermann
