遇到一个问题就是,我标记一个点的时候,怎么知道当前点相对于canvas drawImage()画出来的图片的坐标,当图片缩放的时候,这些点的坐标也跟随缩放,就像你当前的demo里面的缩放,这个坐标的转换搞不懂,求大神解答一下。我的qq 号是2824798771,
貌似画出来的都是狐线。
最好是有规律的
你好,想请教个问题,我最近也有个类似的需求,线上需要标记,就是看了源码,就是咱这个定时刷新的时候背景、line、ball都是要进行重新paint的,就是我自己画贝塞尔曲线的时候,如果不清除掉之前的线条,这条线重绘就越来越模糊,但是清除了(需要全局或区块性清除)就没有扫尾的效果了,这个你遇到过吗,希望能解答一下
