<p><span lang="EN-GB">Hello Laurent,<o:p></o:p></span></p>
<p><span lang="EN-GB">Thank you for your help. I'm very surprised by the complexity of the way to display a raster. I thought that only d.rast was needed. Other grass command are so simple to use...<o:p></o:p></span></p>
<p><span lang="EN-GB">Anayway, I don't understand why you need to set a image width and height. is it pixel number between west to east and south to north from region ?<o:p></o:p></span></p>
<p><span lang="EN-GB">and from where "img_file_name" is coming ? (my layer's name is "my_map")<o:p></o:p></span></p>
<p><span lang="EN-GB">To remove raster from display, I just manually remove from the layer tree.<o:p></o:p></span></p>
