[mapserver-users] Map size question?

[Fawcett, David (MPCA)]

Chris,

If you are in tile mode, I assume that you probably don't want an embedded legend on each tile.

Have you thought about doing a separate call/request/object for the legend?

If you were doing this via CGI, I would recommend doing a separate mode=legend request.

David.

After quite a while thinking I could not produce a legend I have realised that the legend is actually there, just off the edge of my map.

Now I see that although my map file specifies a map size of 640 x 480 pixels, if in single tile mode the map image being produced is actually  1110 x 660 pixels. Alternatively with multiple tiles I get 12 tiles of 250 x 250 pixels which is 1024 x 768 pixels.

It seems that the size parameter in the map file is being ignored (even setting the values to 0 0 or omitting the SIZE parameter altogether makes no difference). MAXSIZE doesn't seem to help either.

I can't find a way to get the image size that I want, can anyone help?

Hi all

I have a map created via Mapscript under Mapserver 6.0 but I can't find a way to add a legend. Recent examples are hard to find but I found the following dating from 2002 which seemed simple enough:


              $legend = $map->legend;
              $legend->set(width,40);
              $legend->set(height,100);
              $legend->imagecolor->setRGB(240,220,200); # tan
              $legend->outlinecolor->setRGB(1,1,1); # black
              $legend->set(status, MS_EMBED);
              $legend->set(position, MS_UL);
              // SET LEGEND LABEL PROPERTIES
              $lg_label = $legend->label;
              $lg_label->set(font, "arial");
              $lg_label->set(type, MS_TRUETYPE);
              $lg_label->set(size, 10);
              $lg_label->set(minsize, 6);
              $lg_label->set(maxsize, 12);
              $lg_label->color->setRGB(100,100,100);
              $legend->set(postlabelcache, MS_TRUE);
              // DRAW LEGEND
              $legendImage=$map->drawLegend();

Unfortunately this produces no output. Can anyone give me any clues why?


Chris
