Flash CS3 & ActionScript 3 Example: Using hasGlyphs() with embedded fonts

This example demonstrates the hasGlyphs() function with an embedded font (no need for Flex2).

Step 1: Embed Font:

Create a new movie and add a new font to your Library:

now edit the linkage properties:

Step 2: Add Code:

Create a new text file with the name Test.as in the same folder and add the following code:

package {
 import flash.display.Sprite;
 import flash.text.TextField;

 public class Test extends Sprite {

   private var textFieldFactory:TextFieldFactory;
  
   public function Test() {
     trace("Embedded Font Test")
     textFieldFactory = new TextFieldFactory();
     var tf:TextField = textFieldFactory.getNewTextField("Bingo!", 0x000000, 14);
     addChild(tf);
   }
  
 }
}

Now create a new text file with the name TextFieldFactory.as in the same folder and add the following code:

package {

 import flash.text.Font;
 import flash.text.TextField;
 import flash.text.TextFormat;
 import flash.text.TextFieldAutoSize;
 import flash.text.TextFormatAlign;
 import flash.text.TextFieldType;
 import flash.text.AntiAliasType;
 import flash.utils.*;


 public class TextFieldFactory {

   private static var embeddedFont:Font = null;

   public function TextFieldFactory() {
     var embeddedFontClass:Class = getDefinitionByName("EmbeddedGaramond") as Class;
     Font.registerFont(embeddedFontClass);
     var embeddedFontsArray:Array = Font.enumerateFonts(false);
     embeddedFont = embeddedFontsArray[0];
   }

   public function getNewTextField(t:String, c:uint, s:uint):TextField {
     if ((embeddedFont != null) && embeddedFont.hasGlyphs(t)) {
       return getNewTextFieldEmbeddedFont(t, c, s)
     }
     else {
       return getNewTextFieldDeviceFont(t, c, s)
     }
   }

   public function getNewTextFieldEmbeddedFont(t:String, c:uint, s:uint):TextField {
     trace("getNewTextFieldEmbeddedFont: "+t);

     var tf:TextField = new TextField();
     var fo:TextFormat = new TextFormat();

     fo.font = embeddedFont.fontName;
     fo.color = c;
     fo.size = s
     tf.defaultTextFormat = fo;
     tf.autoSize = TextFieldAutoSize.LEFT
     tf.type = TextFieldType.DYNAMIC;
     tf.multiline = false;
     tf.selectable = false;
     tf.textColor = c;
     tf.embedFonts = true;
     tf.antiAliasType = AntiAliasType.ADVANCED;
     tf.border = true;
     tf.wordWrap = false;
     tf.text = t;
     return tf;
   }

   public function getNewTextFieldDeviceFont(t:String, c:uint, s:uint):TextField {
     var tf:TextField = new TextField();
     var fo:TextFormat = new TextFormat();

     trace("getNewTextFieldDeviceFont: "+t);
     fo.font = "_serif";
     fo.color = c;
     fo.size = s
     tf.defaultTextFormat = fo;
     tf.autoSize = TextFieldAutoSize.LEFT
     tf.type = TextFieldType.DYNAMIC;
     tf.multiline = false;
     tf.selectable = false;
     tf.textColor = c;
     tf.embedFonts = false;
     tf.border = true;
     tf.wordWrap = false;
     tf.text = t;
     return tf;
   }
  
 }
}

Set the document class to Test and save all files. Pulish and run the movie and you will see the words "Bingo!" set with the embedded font.
