Changing the Dimensions of the Autodesk
MapGuide Spatial Filter
The default client window size determines the size of the spatial filter you use
to limit data returned by a spatial query. Autodesk MapGuide allows you to
change the spatial filter’s extents by applying clipping adjustments that
either increase or decrease the dimensions of the bounding box so that it is
bigger or smaller than the default client size window. The clipping adjust-
ments you apply can be set to either positive or negative values, depending
on whether you want to make the spatial filter larger or smaller than the
default client window size. The units for the clipping adjustment are the
same as the units established for the map coordinate system.
To adjust the spatial filter
1 Open the map containing the layer to which you want to apply clipping
adjustments.
2 Double-click the name of the layer in the list to the left of the map. The
Map Layer Properties dialog box is displayed.
3 In the Map Layer Properties dialog box, click the Data Sources tab, as
shown in the following illustration.
