不必要的缩放图像

Question

When I want to draw image using following functions I always get exactly 3 times bigger image than it's source has. So if I want to have displayed size 1000x1000 I have to resize source image to 335x335 and then it will be uncutted.

screen = new Screen(BitmapFactory.decodeResource(getResources(), R.drawable.rose1), 40, 200, 1000, 1000, 1);

Screen contructor in Screen.java:

public Screen (Bitmap res, int xPos, int yPos, int w, int h, int numFrames){
    super.x = xPos;
    super.y = yPos;
    height = h;
    width = w;
    Bitmap [] image = new Bitmap[numFrames];
    spritesheet = res;

    for (int i = 0; i<image.length; i++){
        image[i] = Bitmap.createBitmap(spritesheet, i*width, 0, width, height);
        //image[i] = Bitmap.createScaledBitmap(spritesheet, width, height, true);
    }

    animation.setFrames(image);
    animation.setDelay(10);
}

But when I use

 image[i] = Bitmap.createScaledBitmap(spritesheet, width, height, true);

everything is OK, but what if I want to add animated object?

Finally I found the solution. Should set the inScaled to false.

BitmapFactory.Options options = new BitmapFactory.Options();
options.inScaled = false;
screen = new Screen(BitmapFactory.decodeResource(getResources(), R.drawable.rain2, options), 40*WIDTH_X/1080, 200*HEIGHT_Y/1920, 1000,1000, 1);
