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

[Traian Stanev]

It should be possible to have the font name be treated as an expression if you use the new symbol definition XML to define the style. Same for color.

Hi Andy

Thanks for your reply on this, in light of what you say, for now we will populate the attribute table with font, weight and colour and then use themeing of the layer, for the different combinations. Not ideal but it solves the problem for now.

Thanks

Gary

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
