Re: [MapServer-users] readGIF error meaning ?
Hello Jeff, Thanks for the reply. Your answer was in my junk folder, sorry for the delay ^^' I found where the error was coming from, if it can interest someone else. My MapFile has thematics (many CLASS with EXPRESSION in LAYER), and some cases use an external GIF resource defined in my SYMBOLSET. It was not well defined, and I also have to change these from GIF to PNG, and now all works well.

Hello JC, If you are using MS4W, you can test a GetLegendGraphic request by using the local demo WMS service that comes with every MS4W install, out-of-the-box, such as: https://ms4w.dev/cgi-bin/mapserv.exe?MAP=/ms4w/apps/local-demo/local.map=WMS=1.1.1=getlegendgraphic=countries=image/png (you should be able to modify the url above for 127.0.0.1/ instead) If that works locally for you, just follow the local-demo.map, for your own mapfile. -jeff -- Jeff McKenna GatewayGeo: Developers of MS4W, MapServer Consulting and Training co-founder of FOSS4G http://gatewaygeo.com/ On 2022-11-07 11:23 a.m., Jean-Christophe Bastin wrote: > Hello, > > I have many map files and I’m trying to get legends from them. > > I followed the documentation I found : > https://mapserver.org/ogc/wms_server.html#getlegendgraphic-request > <https://mapserver.org/ogc/wms_server.html#getlegendgraphic-request> > > The map file I test follows the requirements.

[MapServer-users] readGIF error meaning ?
Hello, I have many map files and I'm trying to get legends from them. I followed the documentation I found : https://mapserver.org/ogc/wms_server.html#getlegendgraphic-request The map file I test follows the requirements. I tried many calls : http://127.0.0.1/cgi-bin/mapserv.exe?MAP=C:/mywms.map=WMS=mylayer=getlegendgraphic=image/png=1.0.0 http://127.0.0.1/cgi-bin/mapserv.exe?MAP=C:/mywms.map=WMS=mylayer=getlegendgraphic=image/png=1.1.0 http://127.0.0.1/cgi-bin/mapserv.exe?MAP=C:/mywms.map=WMS=mylayer=getlegendgraphic=image/png=1.1.1 http://127.0.0.1/cgi-bin/mapserv.exe?MAP=C:/mywms.map=WMS=mylayer=getlegendgraphic=image/png=1.3.0_VERSION=1.1.0 Each of them give me the error : readGIF(): General error message. corrupted gif image?: Failed to read from file What does that mean ? Am I missing a parameter in my call or something more in the map file that is not in the documentation ? Or is it the kind of generic error "I can't generate your legend, just find by yourself why" ?

Re: [mapserver-users] Need help/sample on how to use templating please
Hello, Thank you very much. I was in the good way in the MapFile, but not in the way to test it. I was testing my template using info tool of QGIS, and it was always displaying the base GetFeatureInfo results. I noticed in your execise that you were using OpenLayers and getGetFeatureInfoUrl, so I did a test with an hardcoded url in my browser, and in this way it displays well the template. I don’t know if you use QGIS, but do you have any idea on how to get the template result with it ?

[mapserver-users] How is working TEMPLATE fooOnlyForWMSGetFeatureInfo ?
Hi all, I don't find good explanations about the use of TEMPLATE fooOnlyForWMSGetFeatureInfo in a Mapfile. In fact, I have a queryable WMS, and when I send a GetFeatureInfo request, I get the following answer : "http://www.digitalearth.gov/wmt/xml/exception_1_0_1.dtd;> msReturnPage(): Web application error. Malformed template name (fooOnlyForWMSGetFeatureInfo). What does that mean ? I did a research on "TEMPLATE" and "fooOnlyForWMSGetFeatureInfo", but I don't find how it is used. I only find Mapfile samples using it, but nothing about what and how it is used. Someone can explain me how can I resolve this issue ? Many thanks !
