  fun Drawable.toBitmap(): Bitmap {
        val bitmap = if (this.intrinsicWidth <= 0 || this.intrinsicHeight <= 0) {
            Bitmap.createBitmap(1, 1, Bitmap.Config.ARGB_8888) // Single color bitmap will be created of 1x1 pixel
        } else {
            Bitmap.createBitmap(this.intrinsicWidth, this.intrinsicHeight, Bitmap.Config.ARGB_8888)
        }

        if (this is BitmapDrawable) {
            if (this.bitmap != null) {
                return this.bitmap
            }
        }

        val canvas = Canvas(bitmap)
        this.setBounds(0, 0, canvas.width, canvas.height)
        this.draw(canvas)
        return bitmap
