如何将PictureDrawable转换为ScaleDrawble？

Question

我正在尝试缩放从svg-android-library获得的可绘制图片。我可以创建drawable但不知道如何缩放它。

这是我尝试过的代码：

Drawable drawable = svg.createPictureDrawable();
    int size = 108;
        Bitmap img = Bitmap.createBitmap(size, size, Bitmap.Config.ARGB_8888);
        Canvas canvas = new Canvas(img);
        //resize drawable here according to screen width
        drawable = new ScaleDrawable(drawable, 0, size*2, size*2).getDrawable();
        drawable.setBounds(0, 0, size*2, size*2);
        drawable.draw(canvas);

有什么建议吗？

我用过

Picture picture = svg.getPicture();

然后用一个新的Rect绘制它，它将拉伸它以适应新的Rect

canvas.drawPicture(picture, newRect);
