without a full reload of the map. How it behaves may also depend on other

recalculated.<o:p></o:p></span></p>

<p class=MsoNormal><span style='color:#1F497D'>The label size is set in the
layer definition and for the most part based on the font size if I am not
mistaken. You could implement a +/- on the toolbar which updates the layer
definition to change the size by some fixed increment. Not sure if this is the
best way, but it is one way.<o:p></o:p></span></p>

<p class=MsoNormal>Hello,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I am getting back in to MapGuide development after an
extended hiatus. I am trying to make changes to an application that I
developed a long time ago, and I’m not exactly sure how to accomplish what I am
trying to do. I would like to allow the user to manipulate the size of a
layer’s labels. Ideally, I would like to put a + and – icon on the
toolbar which resizes the labels up or down by some fixed amount. Is this
possible? Can anybody point me to an existing sample or bit of code that
that shows how this would be done? Any assistance that you can offer
would be greatly appreciated. Thanks!<o:p></o:p></p>
