Hello all, I'm developing an aplicattion based on mapserver in which I have a text box to set a numerical scale. This numerical scale ($_scale = 20000) is used to render the image via the following mapscript:
$_scale = 20000; $center_point=ms_newPointObj(); $center_point->setXY($map->width/2, $map->height/2); $map->zoomscale($_scale,$center_point, $map->width, $map->height, $map->extent); However the image retrieved doesn't have the correct dimensions. The graphical scale is correct, but 1 cm on the image doesn't corresponde to 20000 (in this case) on the ground. I know that the RESOLUTION parameter is used to perform scale computations, so what RESOLUTION should I use on the mapfile? RESOLUTION depends on monitor size and monitor resolution, right? How can the server/browser know the monitor size/resolution? Best regards, André Silva
