Constructor LabelDefinition
LabelDefinition(LabelExpression, TextSymbol)
Initializes a new instance of the LabelDefinition class with the specified LabelExpression and TextSymbol.
Declaration
public LabelDefinition(LabelExpression labelExpression, TextSymbol textSymbol)Parameters
| Type | Name | Description |
|---|---|---|
| LabelExpression | labelExpression | The expression script used to calculate the label text. |
| TextSymbol | textSymbol | The text symbol which describes the overall appearance of label text (e.g. font and size). |
Remarks
The label expression may be a combination of literal text and attribute values from the
feature being labeled. The syntax of the expression is determined by which label expression
object is used: ArcadeLabelExpression, SimpleLabelExpression or
WebmapLabelExpression. Warning: If the expression attempts to use attributes
that don't exist, then labels will not be produced. This is distinct from the attribute
existing but having a null or empty value, which can form part of the produced text label.
Likewise, if no TextSymbol has been set, then no labels can be created.
