我正在尝试将文本字段中的所有字母转换为位图数据。然后我想为他们每个人制作动画。我可以使用 getCharBoundaries 返回一个矩形数组。但是,如何将每个字母转换为 BitMapData?
package
{
import flash.display.Sprite;
import flash.geom.Rectangle;
import flash.text.TextField;
import flash.text.TextFieldType;
import flash.text.TextFormat;
public class LetterBitmapData extends Sprite
{
private var tf:TextField;
private var letterSprite:Sprite;
public function LetterBitmapData()
{
makeTF();
getRectangles();
};
private function makeTF():void
{
tf = new TextField();
tf.width = 400;
tf.height = 100;
tf.selectable = false;
tf.multiline = true;
tf.wordWrap = true;
tf.text = "Now is the winter of our discontent made glorious summer by this sun of York.";
tf.setTextFormat(new TextFormat("_sans", 16, 0));
addChild(tf);
}
private function getRectangles():Array
{
var result:Array = [];
var rectangle:Rectangle;
for (var i:int = 0; i < tf.text.length; i++)
{
rectangle = tf.getCharBoundaries(i);
result.push(rectangle); //create an array of CharBoundary rectangles
//trace("RECTANGLE x: " + rectangle.x + " y: " + rectangle.y + " width: " + rectangle.width + " height: " + rectangle.height );
}
return result;
}
}
}
