Canvas Ghost 魔法 | w3cTrain
https://www.w3ctrain.com/2016/12/19/ghost-canvas-magic
说实话，我对 Canvas 真的不熟，没有在任何生产环境用过，除了偶尔自己写 抄 一些 Demo。 今天想分享的是，使用 Canvas Ghost 来做两个神奇的 Demo。 不过这都不重要，我的意思是，通过镜像或者说肉眼看不见的复本来借用 Canvas 的 API，以达到真正目的。 那么就管这个虚无缥缈的 Canvas 叫做 Canvas Ghost。 那么就这个简单的需求，你会有什么解决方案 获取图片上某个位置是否透明 JavaScript 没有这样的 Api 吧 但是 Canvas 有。 Canvas 有个 getImageData 的接口，通过这个接口可以获取到 Canvas 上每一个像素点的像素值。 Ctx = canvas.getContext( '2d'. OnMouseMove 转换坐标，获取 Canvas Ghost 上相对于位置的色值. MousePos = {. X: event.pageX,. PixelPos = convertCoord(mousePos, self.offset);. PixelColor 是个数组，有四个值，分别对应 r,g,b,a. I- ) {.

Add To Home Screen. Notification 依赖于 Google Push API，除非你能让用户都翻过 GFW。 国内 Android 自定义程度极高，大部分厂商自定义桌面，自带浏览器也没有 Add To Home Screen 选项。 接下来看 PWA 的核心，也是这篇文章的重点，Service Worker。 Service worker 权限很高，所以需要运行在 HTTPS 上，防止被人从中攻击，Github Page 支持 HTTPS，是块极好的试验田。 Proudly published with hexo.
