This library can be used for both android and desktop systems. You just need to extend Image differently in both.
Here is one example of how It can be Implemented in android:
public class BitmapImage extends Image {
private Bitmap image;
public BitmapImage(Bitmap b) {
super(b.getWidth(), b.getHeight());
this.image = b;
}
public BitmapImage(File f) {
this(BitMapImage.create(f));
}
private static Bitmap create(File f) {
Bitmap image;
BitmapFactory.Options options = new BitmapFactory.Options();
options.inPreferredConfig = Bitmap.Config.ARGB_8888;
image = BitmapFactory.decodeFile(f.getAbsolutePath(), options);
return image;
}
@Override
public Color getColor(int x, int y) {
return new Color(image.getPixel(x, y));
}
@Override
public Image getScaledInstance(int width, int height) {
Bitmap resized = Bitmap.createScaledBitmap(this.image, width , height, true);
return new BitMapImage(resized);
}
}Desktop Implementation using awt package
