您好,最近在我自己的项目中使用DrawLine在地图上绘制折线,在点击最后一个点来完成绘制时会有(regl) invalid buffer data以及(uncatch in Promise)nvalid buffer data 的报错,一直没能解决,前来请教。我在codesandbox里运行如下代码: import { AMapScene, LineLayer }
Canvas(Bitmap bitmap): 以bitmap对象创建一个画布,则将内容都绘制在bitmap上,因此bitmap不得为null。 Canvas(GL gl): 在绘制3D效果时使用,与OpenGL相关。 drawColor: 设置Canvas的背景颜色。 setBitmap: 设置具体画布。 clipRect: 设置显示区域,即设置裁剪区。
