>From Openlayers document, it can be found:
MapGuide OS uses a DPI value and degrees to meters conversion
factor that are different than the defaults used in OpenLayers, so these
must be adjusted accordingly in your application. See the MapGuide example
for how to set these values for MGOS.
>From mapguide.html, it can be found:
var metersPerUnit = 111319.4908; //value returned from mapguide
var inPerUnit = OpenLayers.INCHES_PER_UNIT.m * metersPerUnit;
OpenLayers.INCHES_PER_UNIT["dd"] = inPerUnit;
OpenLayers.INCHES_PER_UNIT["degrees"] = inPerUnit;
OpenLayers.DOTS_PER_INCH = 96;
it seems both OpenLayers.INCHES_PER_UNIT and OpenLayers.DOTS_PER_INCH are
global settings.
I doubt if two different layers, such as WMS and MapGuide are added to
Openlayers Map, the above settings will influence both layers. but it seems
the settings shouldn't be changed for WMS?
