Re: [mapserver-users] Mapserver WMS under IIS 7 x64 serving up blank images
I figured out what was going on. It was an easting-northing mixup in the map and layer extents. Apparently earlier versions of mapserver/mapscript tolerated the bug. Anyway it's all working now under Windows Server 2008 x64 and IIS 7 FastCGI. A big thanks to the mapserver community. Open source rocks!

[mapserver-users] Mapserver WMS under IIS 7 x64 serving up blank images
Thanks to all who've been helping me along. I'm getting close to having x64 working now. I've worked through a slew of issues over the weekend, most related to permissions. My latest issue is that mapserv.exe, when invoked via IIS 7's FastCGI (classic mode) module, is returning blank images. GetCapabilities is working fine, and the GetMap images are the right size and format, but they're blank. Here's my setup: I downloaded and installed the x64 binaries (from Tamas, thanks!) into a single directory (C :\mapserver\). The IIS impersonated user has sufficient privileges on this folder and all data folders. I am accessing mapserver's WMS service with this URL: http://www.fireimagery.com/ms/mapserv.exe?map=C%3A%2Fmaps%2FA091207074551.mapSERVICE=WMSREQUEST=GetMapWIDTH=1680HEIGHT=536FORMAT=image/pngLAYERS=ZZS0TYLE=BGCOLOR=0x88TRANSPARENT=FALSEVERSION=1.3.0CRS=EPSG:4326BBOX=36.0156802563091,-123.307040153269,37.2036688809148,-119.583493717938EXCEPTIONS=XML The corresponding mapfile text is as follows: MAP EXTENT 36.0992948502284 -121.822480778145 36.3421121497716 -121.520865221855 IMAGECOLOR 255 255 255 IMAGETYPE PNG SIZE -1 -1 STATUS ON UNITS DD CONFIG PROJ_LIB C:/mapserver/ NAME A091207074551 OUTPUTFORMAT NAME aggpng24 MIMETYPE image/png DRIVER AGG/PNG EXTENSION PNG IMAGEMODE RGBA TRANSPARENT TRUE END PROJECTION init=epsg:4326 END QUERYMAP COLOR 255 255 0 SIZE -1 -1 STATUS OFF STYLE HILITE END WEB IMAGEPATH IMAGEURL METADATA wms_titleA091207074551 END QUERYFORMAT text/html LEGENDFORMAT text/html BROWSEFORMAT text/html END LAYER DATA C:\rawimages\A091207074551_output\A091207074551_0_config_PROCESS_RESULTS\BASINCOMPLEX_ftp.coloradoskye.com_2008_CA_Siege_080627_1200Local_SPOT_NIR_OUT.PNG EXTENT 36.0992948502284 -121.822480778145 36.3421121497716 -121.520865221855 METADATA wms_srsEPSG:4326 wms_extent36.1 -121.8 36.3 -121.5 wms_title BASINCOMPLEX_FTP.COLORADOSKYE.COM_2008_CA_SIEGE_080627_1200LOCAL_SPOT_NIR END NAME ZZ PROJECTION init=epsg:4326 END STATUS ON TYPE RASTER UNITS DD END END I have tried several different image formats and drivers, all produce blank images.
