Canvas的drawPoint

Posted 2021-01-03 endian11

• Paint.setStrokeCap(cap) 可以设置点的形状，但这个方法并不是专门用来设置点的形状的，而是一个设置线条端点形状的方法。端点有圆头 (ROUND)、平头 (BUTT) 和方头 (SQUARE) 三种，具体会在下一节里面讲。

•         Path path = new Path();
          path.addCircle(250,300,100, Path.Direction.CCW);
          canvas.clipPath(path);
          Bitmap bitmap = BitmapFactory.decodeResource(getResources(), R.drawable.aa);
          canvas.drawBitmap(bitmap,100,100,paint);
  
          paint.setColor(Color.RED);
          paint.setStyle(Paint.Style.FILL);
          paint.setStrokeWidth(20);
          paint.setStrokeCap(Paint.Cap.ROUND);
          canvas.drawPoint(250,220,paint);
