Constructor Details
Creates a new TextSymbol object that includes only the text.
Parameters:
< |
Required | Text string for display in the graphics layer. |
Sample:
Create a new text symbol using the default values for color, size, etc.
require([
"esri/symbols/TextSymbol", ...
], function(TextSymbol, ... ) {
var textSym = new TextSymbol("Hello World");
...
});
Create a new text symbol and set new values for color, weight, font and angle.
require([
"esri/symbols/TextSymbol", "esri/Color", "esri/symbols/Font", ...
], function(TextSymbol, Color, Font, ... ) {
var textSymbol = new TextSymbol("Hello World").setColor(
new Color([128,0,0])).setAlign(Font.ALIGN_START).setAngle(45).setFont(
new Font("12pt").setWeight(Font.WEIGHT_BOLD)) ;
...
});
Creates a new TextSymbol object.
Creates a new TextSymbol object using a JSON object.
Parameters:
< |
Required | JSON object representing the TextSymbol. View the Symbol Objects (Common data types in ArcGIS) for details
on creating a JSON symbol. Note that when specifying symbol width and height using JSON the values should be entered in points, the JavaScript API then converts the point values to pixels. The TextSymbol does not support backgroundColor, borderLineColor, verticalAlignment or horizontalAlignment properties. |
