Help with the method copyPixels

Question

Hello good day!
I need a force in  a scheme that I am doing with a combobox that I created to select a  font of a text. I would like to display the text to the source, but do  not want to imply load all sources that I am offering 30, then a  solution that I thought it would be feasible to use an image with these  sources, then in that case all that needs to be done would be to carry this image that has about 30kb which would be a process not so  slow.
For this did the following: I created the image in my library  as a movie clip and then used two BitmapData and a bitmap to display the  image as follows:
    var bmp: Bitmap;
    / / Lista_fonte  is my image of the sources
    var list: = new  lista_fonte lista_fonte ();
    / / Create a  BitmapData from the list instantiated
    var bmd:  BitmapData = new BitmapData (lista.width, lista.height, true);
    / / Create a BitmapData less for the item from combobox
    var bmdtemp:  BitmapData = new BitmapData (lista.width, 20, true);
And then I go  with a paragraph of the sources and use the copyPixels to copy part of  the image:
    for (var i: int = 0; i <30; i) (
        bmdtemp.copyPixels (bmd, new Rectangle (0,0, lista.width, 20),  new Point (0, 20 * i));
        bmp = new  Bitmap (bmdtemp);
        addChild (bmp);
Above would look like this,  but I have two problems:
1 The picture is transparent with the  background and create the BitmapData I allow there is an overhead  transparency, but the picture shows a white background!
2 are just  copying the image at position 0.0 in the case is with any combo of the  first source image only.
I hope that was clear, please help me now  to break the head at a time on it and I read in some forums and some  discusões around and nothing.

But my actual question remained unanswered. Would you please take a look at the method if you have some time and explain to me how the method is converting the IP to decimal.
public class CharTest {
    public static void main(String[] args) {
        int b = '0';
        System.out.println(b);
}This prints out 48. What do you think the significance of that is, and what do you think would happen if I did
int c = '8' - '0';
System.out.println(c);
