[mapguide-users] Dynamically specify colour and font of labels

[Andy Morsell]

Dave,
This is on a Windows localhost, so the fonts specified exist.  It looks like
it's using ZDingbats in my case...
 
The experiment was really to see if it will look at an expression in the
FontName element like it will for the size or label.  It appears that it
will not.

This behavior sounds similar to an issue we saw a while back where if the
server can't find the font requested it defaulted to the last font in the
list which was wingdings or webdings.
 
In your case does the font you specified exist on your client machine and
not your server or are they the same box?

I did a little playing around with this.  I modified the layer XML and then
uploading that modified XML for that layer resource via the mapagent.  I
created a field in a table called Font and populated that with the various
fonts I wanted.  Then I saved the layer XML from Autodesk MapGuide Studio,
modified it in Notepad++ and then uploaded via the mapagent.  The result was
that the label font for all labels was some odd symbol font, not one of the
names I had in the table.
 
<Label>
            <Unit>Inches</Unit>
            <SizeContext>DeviceUnits</SizeContext>
            <SizeX>0.3</SizeX>
            <SizeY>ToInt32 (Height)</SizeY>
            <Text>Camera_ID</Text>
            <FontName>"Font"</FontName>
            <ForegroundColor>ff000000</ForegroundColor>
            <BackgroundColor>ffffffff</BackgroundColor>
            <BackgroundStyle>Ghosted</BackgroundStyle>
            <AdvancedPlacement>
              <ScaleLimit>0.5</ScaleLimit>
            </AdvancedPlacement>
 </Label>
 
So, based on this, it looks like the font cannot be dynamically driven on a
label by label basis.  A good question is, at the core of MGOS, is it using
one font and color value for an entire layer or theme category or is it on
an object by object basis?  If the latter, then it seems like it might not
be too large of a task to modify the core code with this change.  This would
be a good item for an enhancement request.

Hi 
 
As I have had no response, do I take it the answer is no, it can't be done?
 
Thanks
 
Gary

Hi 
 
I know it possible to specify the height, rotation and justification of
feature labels dynamically, using attribute data. But is there a way to do
if for font and colour, i.e. have the font and colour of a label stored as
an attribute?
 
Thanks
 
Gary
