[mapguide-users] Tooltip on MapGuide Web API

[Chris Claydon]

I'm pretty sure that QUERYMAPFEATURES ends up calling the QueryFeatures method on the MgRenderingService. You'll need to create a geometry object that corresponds to the point you're clicking on. It is best to make it a small square rather than a single point, in order for the spatial filter to pick up the underlying feature. And it should use coordinates in the same coordinate system as the map (not image pixel cords).

The operation is called "QUERYMAPFEATURES", but I can't seem
to find it as a function from the Web API.
You can see it in use if you look in the file:
C:\program files\MapGuideOpenSource2.0\WebServerExtensions\www\viewerfiles\ajaxmappane.templ
line 2555.

How could I get the Tooltip on a point using MapGuide Web API?



Example:

I have generated an image using MgRenderingService.RenderMap, and after

that I want to get the tooltip on a point of this image, using the

coordinates on image pixels or converting them to lat-lon.



But I haven't found any method that makes this.
