|
||
69 | * This is a <b>wrapper</b> to be able to use a SmartTextSymbol as a
|
||
70 | * LabelClass. A SmartTextSymbol uses a line instead of a point.
|
||
71 | * Being in fact a Line and not a Marker, it does not make any sense
|
||
72 | * to have label styles since the label styles are well-defined rectangle
|
||
73 | * areas where texts are placed in fields backgrounded by an image. In this
|
||
74 | * contexts, the area is defined dinamically for each line, and there is no
|
||
75 | * sense to have texts fields. They will be rendered as a single string
|
||
76 | * along a line.<br>
|
||
77 | * </p>
|
||
78 | * <p> The label itself is the SmartTextSymbol,
|
||
79 | * the geometry (the line), the label expression,
|
||
80 | * and the text applied to the symbol.<br>
|
||
81 | * </p>
|
||
82 | * <p>
|
||
83 | * Most of the operations performed by this LabelClass are in fact
|
||
84 | * delegated to the symbol.<br>
|
||
