如何绘制平滑/圆形路径？ [英] How to draw smooth / rounded path?

问题描述

我创造的路径，并使用 path.moveTo（X，Y）和 path.lineTo（X将在每个路径多行， Y）。然后 canvas.drawPath（路径，涂料）正在起草的所有路径。但也有一些路径字里行间1-2像素空间。如何删除这些空间？我的code是这样的事情：

 颜料=新的油漆（）;
paint.setColor（Color.RED）;
paint.setStyle（Paint.Style.FILL_AND_STROKE）;
paint.setDither（假）;
paint.setStrokeWidth（3）;
paint.setAntiAlias​​（真正的）;

的for（int i = 0; I＆LT;长度;我++）{
     路径path =新路径（）;
     path.moveTo（A，B）;
     path.lineTo（C，D）;
     path.moveTo（C，D）;
     path.lineTo（E，F）;
     canvas.drawPath（路径，油漆）;
}
 

解决方案

也许这将创造你想要什么

  paint.setColor（彩色）; //设置颜色
    paint.setStrokeWidth（大小）; //设置大小
    paint.setDither（真正的）; //设置抖动为true
    paint.setStyle（Paint.Style.STROKE）; //设置斯托克
    paint.setStrokeJoin（Paint.Join.ROUND）; //设置连接圆你想
    paint.setStrokeCap​​（Paint.Cap.ROUND）; //设置漆盖圆太
    paint.setPathEffect（新CornerPathEffect（10））; //设置路径的效果，当他们加入。
    paint.setAntiAlias​​（真正的）; //设置抗混所以平滑

I am creating Paths and adding multi lines in each path by using path.moveTo(x, y) and path.lineTo(x, y). Then canvas.drawPath(path, paint) is drawing all paths. But there are 1-2 pixel space between lines in some paths. How can I remove these spaces? My code is something like that:

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);
}

解决方案

Maybe this will create what you want

    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
