FMX形状组件无法正确显示在Android平台上

正如您所见，Windows平台上的形状组件正常显示，非常流畅（包括线条，角落和渐变效果）。FMX形状组件无法正确显示在Android平台上

但在Android平台上，你就会得到一个不能接受的结果：行不再光滑，边角不能被关闭，梯度变成全黑。

如何发生的？以及如何解决它？

我相信它说的笔画（线）梯度不要任何东西，但Windows的2D渲染的工作文档。但是，我无法找到它说的地方。如果你想在Windows版本使用3D，你可以这样做：

initialization 
FMX.Types.GlobalUseGPUCanvas := True;

您还可以通过overriding the rendering parameters开启多重采样。最后，如果需要，您可以使用native Android component作为原生绘图。

仍然无法解决我的问题。 – Leo 2014-10-29 03:56:58

您是否需要在运行时更改对象？就像你在做绘画一样？如果没有，有办法将Windows外观缓存到位图。 – FMXExpress 2014-10-31 22:36:18

是的，我需要在运行时更改这些对象。 – Leo 2014-11-07 01:18:09
