[mapserver-users] problem with raster

[Rahkonen Jukka]

Hi,

Image seems to show just your background colour. I guess that either Mapserver cannot find your image or the extents of the request do no hit the image extenst. Try to give absolute path to your image at 'data\La_Dehesa_1_Mapa_WGS84.tif'. Other suggestions is to add MS_ERRORFILE on map level and DEBUG 5 on layer level to your mapfile and see from the log what happens.
What client do you use as a client and what does the request look like?

Hi Jeff

 i removed projections objects, i use QGIS to get the extent parameter, but
the result is the same

new mapfile

MAP

'
      'wms_srs'             'EPSG:4326'
    END
  END
