Question

我在dlib的帮助下开发了一个Android应用程序，我有一个代码，在68个面部标志的帮助下，我为嘴唇的外部绘制了一条路径，另一个用于嘴唇的内部路径是任何有两条不同路径的方式我可以填补它们之间的空白吗？我已经看过像这样的方法，填充外部的一个并用白色填充内部，所以看起来你只是在外面画部分，但我不能这样做，因为我将它画在一个图像上，我只是想着色嘴唇，有什么办法可以做到这一点吗？

这是我用来画嘴唇的代码：

for (final VisionDetRet ret : results) {
    // Draw landmark
    int x = 0;
    ArrayList<android.graphics.Point> landmarks = ret.getFaceLandmarks();
    int ppX = 0, ppY = 0;
    Paint mFaceLandmardkPaint = new Paint();
    mFaceLandmardkPaint.setColor(Color.GREEN);
    mFaceLandmardkPaint.setStrokeWidth(2);
    mFaceLandmardkPaint.setStyle(Paint.Style.STROKE);
    Path pth = new Path();
    pth.setFillType(Path.FillType.EVEN_ODD);
    Path pth2 = new Path();
    pth2.setFillType(Path.FillType.EVEN_ODD);

    for (android.graphics.Point point : landmarks) {

        if (x >= 48 && x <= 60) {
            int pointX = (int) (point.x);
            int pointY = (int) (point.y);

            if (x != 48) {
                //canvas.drawLine(pointX, pointY, ppX, ppY, mFaceLandmardkPaint);
                pth.lineTo(pointX, pointY);
            } else {
                pth.moveTo(pointX, pointY);
            }
            ppX = pointX;
            ppY = pointY;
            //canvas.drawCircle(pointX, pointY, 1, mFaceLandmardkPaint);
            } else if (x > 60) {
                pth.close();
            }
            if (x >= 61) {
                int pointX = (int) (point.x);
                int pointY = (int) (point.y);
            if (x != 61) {
                //canvas.drawLine(pointX, pointY, ppX, ppY, mFaceLandmardkPaint);
                pth2.lineTo(pointX, pointY);
            } else {
                pth2.moveTo(pointX, pointY);
            }
            ppX = pointX;
            ppY = pointY;
            //canvas.drawCircle(pointX, pointY, 1, mFaceLandmardkPaint);
        }
        x++;
    }
   pth2.close();
   Paint red = new Paint();
   red.setColor(android.graphics.Color.RED);
   red.setStyle(Paint.Style.FILL);
   c.drawPath(pth2, mFaceLandmardkPaint);
   c.drawPath(pth, red);
}

此代码生成一个完整的画嘴。有没有办法用原生画布，颜料和路径来实现这个目标？
