Q&A - Question

We have figured out how to change the label and label shadow colors for a layer. Now I am trying to adjust the font size larger and smaller, but when I do this, the labels disappear instead of changing in size, and they won't come back.

Below is my function, which we want to call for multiple symbol layers in our map. What am I doing wrong? Is there a better way to do this? The config file has these labels at 8 point font. We want to adjust from 6 to 20 points depending on user preference.

Thank you,

Scott

procedure SetLayerLabelColors(L : TGIS_LayerVector);
var
  P : TGIS_ParamsSectionVector;
begin
  // Change parameters for each layer
  if (L.ParamsList.Count > 0) then begin
    if (L.ParamsList[0] is TGIS_ParamsSectionVector) then begin
      P := TGIS_ParamsSectionVector(L.ParamsList[0]);

      // Colors are of type TGIS_Color
      // I am able to change the font colors at run time, no problems
      P.Labels.Color := cSymbolLabelShadowColor;
      P.Labels.FontColor := cSymbolLabelColor;

      // If I uncomment this line and change the font size at runtime, my labels disappear
      // P.Labels.FontSize := iFontSize;
    end;
  end;
end;
