Android的android.graphics.Path宽度限制在2036？ [英] Android android.graphics.Path width limited to 2036?

问题描述

我想绘制一个路径很长的线。该生产线是正确显示，直到到2036 X的目标价值。

I am trying to draw a very long line with a Path. The line is correctly displayed up until to a x target value of 2036.

当我打电话path.lineTo（2037，Y）是不绘制整个路径。到canvas.drawPath（路径，涂料）的调用什么也不做。

when i call path.lineTo(2037, y) the entire path is is not drawn. The call to canvas.drawPath(path, paint) does nothing.

有一个问题，我不知道的？

Is there a problem i am not aware of?

在第二个音符......当我画点的通过canvas.drawLines相同的序列（浮动[]，油漆）的线条绘制正确，但他们没有抗锯齿。是否与抗锯齿和drawLines问题？

On a second note... when i draw the same sequence of points via canvas.drawLines(float[], paint) the lines are correctly drawn but they are not antialiased. Is there a problem with antialiasing and drawLines?

推荐答案

有与硬件加速的限制：一个路径只能是大约2048像素宽和高上最GPU的

There is a limitation with hardware acceleration: a Path can only be about 2048 pixels wide or high on most GPUs.

行抗锯齿应的Andr​​oid 3.2的工作与硬件加速。

Line anti-aliasing should work as of Android 3.2 with hardware acceleration.
