如何绘制平滑/圆形路径？

Question

我正在创建路径并使用path.moveTo(x, y)和在每个路径中添加多行path.lineTo(x, y).然后canvas.drawPath(path, paint)绘制所有路径.但是在某些路径中,行之间有1-2个像素空间.我怎样才能删除这些空格？我的代码是这样的:

paint = new Paint();
paint.setColor(Color.RED);
paint.setStyle(Paint.Style.FILL_AND_STROKE);
paint.setDither(false);
paint.setStrokeWidth(3);
paint.setAntiAlias(true);

for (int i = 0; i < length; i++) {
     Path path = new Path();
     path.moveTo(a, b);
     path.lineTo(c, d);
     path.moveTo(c, d);
     path.lineTo(e, f);
     canvas.drawPath(path, paint);
}

Answer 1

也许这会创造你想要的东西

paint.setColor(color);                    // set the color
paint.setStrokeWidth(size);               // set the size
paint.setDither(true);                    // set the dither to true
paint.setStyle(Paint.Style.STROKE);       // set to STOKE
paint.setStrokeJoin(Paint.Join.ROUND);    // set the join to round you want
paint.setStrokeCap(Paint.Cap.ROUND);      // set the paint cap to round too
paint.setPathEffect(new CornerPathEffect(10) );   // set the path effect when they join.
paint.setAntiAlias(true);                         // set anti alias so it smooths

你可能不想lineTo(c, d),然后立即moveTo(c, d)这是同一点.如果你这样做,你将不会在两个线段上得到一个漂亮的角连接,这可能看起来像一个丑陋的差距.

尝试删除它moveTo.
