[mapserver-users] The browser can't display the rendered image

Wed Nov 19 12:22:51 PST 2008

Hello,

I still have got a problem. I ve tested my mapfiles (with quickmap.php) and
they work fine, but the problem is the same. My php/mapscript code created
the map image and saved it to "/ms_tmp/" but the browser couldn't display it
(I got a broken img). I enclose the php/mapscript file, the mapfile and the
page source.Thx for ur help and patience.

PHP/MAPSCRIPT FILE:

<?php
define( "MAPFILE", "/ms4w/apps/raster/raster.map" );
define( "MODULE", "php_mapscript.dll" );
if(!extension_loaded("mapscript")) dl(MODULE);
$oMap = ms_newMapObj( MAPFILE );
//draw
$oImage = $oMap->draw();
//output map
$url = $oImage->saveWebImage();
?>
<HTML>
   <HEAD>
      <TITLE>Example 1: Displaying a map</TITLE>
  </HEAD>
  <BODY>
      <IMG SRC="<?php echo $url; ?>">
  </BODY>
</HTML>

MAPFILE (I created it with qgis):

MAP
  NAME world_raster
  SIZE 600 600
  UNITS dd

Page source (after I ran the code the html part saw the link to the image
but didn't display it.):
