[mapguide-users] RE: Theme layer application - point featurelayers

[Arnaud De Groof]

Hi Chris,

 

Your analysis was correct. The version of the layer definition
represents the problem. After the updating of the style template
(arearuletemplate.xml and pointruletemplate.xml) to include the extra
setting, the application is successful executed. 

I have posted a new message concerning the theme layer application (see
http://lists.osgeo.org/pipermail/mapguide-users/2009-January/016237.html
) because I would apply a degraded color. Currently, the colors are
randomly distributed.

 

Thanks,

 

Arnaud

I suspect that the cause of the problem is that the Sheboygan sample
layer uses a 1.0.0 layer definition and your own layer uses a 1.1.0
layer definition. The SizeContext element was added to the StrokeType
element in the later version of the schema, thus if you want to use the
Theme code with a newer layer, you'll need to update the style template
(arearuletemplate.xml) to include the extra setting.

 

BTW - SizeContext can be set to either DeviceUnits or MappingUnits. If
set to DeviceUnits, the line width is interpreted in the units of your
screen, and remains constant regardless of the map scale. If set to
MappingUnits, it is interpreted as a real-world size, and thus will
increase in width on the screen as you zoom in.

 

Chris.

Thanks for this information; I have modified the file
(../phpviewersample/theme/classes/theme.php) according your remarks.
Now, I have the possibility to select the point layers. I changed also
the different reference to the <AreaRule> by <PointRule>. I do not know
if these changes are correct because I have a problem with this function
(polygon layers), see
http://lists.osgeo.org/pipermail/mapguide-users/2009-January/016202.html

The sample code generates <AreaRule> elements in a layer definition, and
therefore applies only to polygon styles. It should be relatively easy
to modify it to handle point layers and styles instead.

Hello,

 

Is it possible to use the application "Theme Layer" with point feature
layers? The code sample (phpviewersample/theme) allows only selecting
the polygon feature layers.

 

Thanks,

 

Arnaud De Groof
