[mapserver-users] Σχετ: Problem with CGI results

[Stefanos Anastasiou]

OK I got it....
My IMAGESIZE is set to 800 600 in the mapfile
In my template the CGI parameters in the form are set to <input type="image" name="img" src="[img]" width="700" height="500">.
It seems that the width and height values have to be the same on both the mapfile and the template...or not set in the template at all.

 Hi Stefanos,

When I try this locally with CGI, I also get the same value on first 
load for [mapx] and [mapy] of -1.0000,-1.0000 likely because there is no 
point click yet.  But when I do click, the values for [mapx] and [mapy] 
returned look valid.

You might also want to check the returned values for [maplat] [maplon] 
as well.

If it is related to a projection issue, you might want to check the 
mailing list archives for relevant discussions, such as 
http://osgeo-org.1560.x6.nabble.com/retrieve-map-coordinates-with-different-EPSG-td5000369.html

I am testing with MS4W 3.1.3 (MapServer 7.0.1).
