android - 用 `canvas.clipRect` 替代已弃用的 `Region.Op.REPLACE` ？

Question

我有以下代码:

 private RectF tmpRect = new RectF();

 public void drawClipedBitmap(Bitmap bmp, Polygon tmpPoly, int x, int y) {
    this.canvas.clipPath(getPath(tmpPoly));
    this.canvas.drawBitmap(bmp, (float) x, (float) y, this.fillPaint);
    this.tmpRect.set(0.0f, 0.0f, (float) this.canvas.getWidth(), (float) this.canvas.getHeight());
    this.canvas.clipRect(this.tmpRect, Op.REPLACE);
}

但自 Android SDK28 以来，clipRect 的实现已被弃用并退出。
我正在尝试 4 个小时来找到一种方法来用其他方法替换该方法，但未成功。

由于 clipRect 已被弃用且不再工作，我如何获得相同的结果？

我自己发现:

public void drawClipedBitmap(Bitmap bmp, Polygon tmpPoly, int x, int y) {
        Path p = getPath(tmpPoly);
        Log.d("POINTS","POINTS: "+p);
        this.canvas.clipPath(getPath(tmpPoly));
        this.canvas.drawBitmap(bmp, (float) x, (float) y, this.fillPaint);
        this.tmpRect.set(0.0f, 0.0f, (float) this.canvas.getWidth(), (float) this.canvas.getHeight());
        //this.canvas.clipRect(this.tmpRect, Op.REPLACE);
        this.canvas.save();
        float fWidth = (float)this.canvas.getWidth();
        float fHeight = (float)this.canvas.getHeight();
        //this.canvas.drawRect(0, 0, fWidth, fHeight, new Paint());
        this.canvas.clipRect(0.0f, 0.0f,  fWidth, fHeight);
        this.canvas.restore();
    }
