Usage

From source file:Main.java

public static int PutImageTargetHeight(Canvas canvas, Drawable image, int x, int y, int height) {
    // float scale = (float)height / (float)image.getBounds().height();
    // int width = (int)Math.round(image.getBounds().width() * scale);

    float scale = (float) height / (float) image.getIntrinsicHeight();
    int width = (int) Math.round((float) image.getIntrinsicWidth() * scale);

    Rect oldBounds = image.getBounds();/*from  w ww . j av  a2 s  .  c om*/
    image.setBounds(x, y, x + width, y + height);
    image.draw(canvas);
    image.setBounds(oldBounds);
