Nelson, If you know the geographic extent of the image, you could create a world file for it by hand. MapServer should recognize it then.

Hello, I have a PNG that I would like to use as an overlay for a 2x6 set of aerial tiles. I just want to use MINSCALE and MAXSCALE to turn one and the other off and on. That isn't the problem I'm having. I can't get the PNG to display. The file itself is fine, but I can not make a mapfile display the PNG. I have made a new mapfile that I want to just display the PNG first before possibly integrating it into the same mapfile as my tileindex. I know that the PNG is supposed to be georeferenced but I don't know how to create those files so I would like to use GDAL to output the PNG as I hear It will simply apply the extents. Here is what I have: MAP NAME 'overlay' SIZE 800 650 STATUS ON EXTENT 201000.000000 874000.000000 213000.000000 882000.000000 UNITS METERS FONTSET '../fonts/fontset.list' SYMBOLSET '../symbols/symbol.sym' TRANSPARENT OFF IMAGETYPE PNG OUTPUTFORMAT NAME png DRIVER "GDAL/PNG" MIMETYPE "image/png" FORMATOPTION "TARGET=95" IMAGEMODE PC256 END QUERYMAP STATUS ON STYLE SELECTED END WEB INCLUDE "/ms4w/apps/GeoMOOSE/maps_test/web_config.map" END LEGEND STATUS OFF END LAYER NAME "overlay" STATUS DEFAULT TYPE RASTER DATA "overlay.png" #MINSCALE 14000 END END ## end Map Also, the PNG is color. I would like my overlay to certainly be in color. The mapfile and png are in the same dir. _______________________________________________ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users _______________________________________________ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users
