Label visualisation

For point and polygon data, labels can be visualised in the map view. Available visualisation-style subitems for labels:

parameter<string>  LabelText      := 'Netherlands'   , DialogType = "LabelText";
parameter<uint32>  LabelColor     := rgb(255,0,0)    , DialogType = "LabelColor";
parameter<uint32>  LabelBackColor := rgb(255,255,0)  , DialogType = "LabelBackColor";
parameter<float32> LabelSize      := 8f              , DialogType = "LabelSize"
parameter<meter>   LabelWorldSize := 10[meter]       , DialogType = "LabelWorldSize";
parameter<string>  LabelFont      := 'Arial'         , DialogType = "LabelFont";

description

• LabelText: a data-item with value-type string and as expression the labels to be visualised.
• LabelColor: a data item with value type uint32 and as expression a (set) of rgb values, used to configure the color of the text.
• LabelBackColor: a data item with value type uint32 and as expression a (set) of rgb values, used to configure to background frame color around the text.
• LabelSize: a data item with value type float32 and as expression a (set) of values indicating the fontsize in pixels
• LabelWorldSize: a data item with the same values unit as the values unit of the base unit for the coordinate system. The LabelWorldSize specifies a size in e.g. meters, which is dependent on the zoom level in the map view. With this property a zoom dependent size can be configured.
• LabelFont: a data item with value type string and as expression the font to be used.
