Hi all,
I'm trying to construct a mapserver URL to fetch an image from php. I'm
change some of the mapfile parameters in the url. Do I need validation
blocks for these changes? I assume I do not because I am getting a scale
bar. I'm only getting a blank image.
http://imaptools.com:8080/cgi-bin/mapserv?mode=map&map.projection=init=epsg:900913&map=/u/data/tiger2013-maps/tiger2013-mc.map&layers=all&imagetype=jpeg&MAPSIZE=541+522&map.scalebar=status+embed+units+feet&SCALEDENOM=3000&MAPXY=-7946835.7326273+5254288.4981293
The projection for the map object is epsg:4326 in the mapfile.
I appear to be getting a png image despite the request for a jpeg?
MapServer version 6.2.1 OUTPUT=GIF OUTPUT=PNG OUTPUT=JPEG SUPPORTS=PROJ
SUPPORTS=GD SUPPORTS=AGG SUPPORTS=FREETYPE SUPPORTS=CAIRO
SUPPORTS=SVG_SYMBOLS SUPPORTS=ICONV SUPPORTS=FRIBIDI SUPPORTS=WMS_SERVER
SUPPORTS=WMS_CLIENT SUPPORTS=WFS_SERVER SUPPORTS=WFS_CLIENT
SUPPORTS=WCS_SERVER SUPPORTS=SOS_SERVER SUPPORTS=FASTCGI
SUPPORTS=THREADS SUPPORTS=GEOS INPUT=JPEG INPUT=POSTGIS INPUT=OGR
INPUT=GDAL INPUT=SHAPEFILE
The MAPXY should be equivalent to -71.38764, 42.61986 if I did the
conversion correctly.
Any idea what I'm doing wrong here?
And it works if I don't change the projection:
http://imaptools.com:8080/cgi-bin/mapserv?mode=map&map=/u/data/tiger2013-maps/tiger2013-mc.map&layers=all&MAP_IMAGETYPE=jpeg&MAPSIZE=541+522&map.scalebar=status+embed+units+feet&SCALEDENOM=3000&MAPXY=-71.38764+42.61986
And it works as WMS:
http://imaptools.com:8080/cgi-bin/mapserv?MAP=%2Fu%2Fdata%2Ftiger2013-maps%2Ftiger2013.map&FORMAT=image%2Fjpeg&MAP_IMAGETYPE=jpeg&LAYERS=Tiger_2013&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&STYLES=&EXCEPTIONS=application%2Fvnd.ogc.se_inimage&SRS=EPSG%3A900913&BBOX=-7947363.3342296,5253914.7041195,-7946527.3042538,5254571.5848149&WIDTH=700&HEIGHT=550
Thanks,
