Three.js canvas.toDataURL sometimes blank

由 淺唱寂寞╮ 提交于 2020-06-12 06:49:27
问题 I'm trying to render a THREE.js scene + some overlaid HTML elements using html2canvas.js. It works most times , but not all the time. In the failure cases, the HTML elements are rendered (the background, overlays, etc.) but nothing else. The THREE.js scene acts as if it's completely empty, even though it visibly has data in it. I can say that it usually fails for larger models, but only early into the rendering. It does eventually work in all cases, but the larger models take about 30 seconds

JS 如何将“在线图片资源”转换成“base64”

在实现html2canvas截图的功能时，会报下面的错误； Uncaught DOMException: Failed to execute 'toDataURL' on 'HTMLCanvasElement': Tainted canvases may not be exported 原因一：图片资源跨域 解决方法：将“跨域图片资源”转换成base64后，用base64渲染img标签，这样完美解决问题； 如何将“跨域图片”转换成base64呢？原理很简单，将img绘制成canvas，再将canvas转换成base64的img流； 因为图片是跨域的，所以我们在转换过程中需要加一段代码，用来处理跨域； image.crossOrigin = " * " ; // image.crossOrigin = 'Anonymous'; // 这个也可以 继续执行，发现偶尔还是报错，麻麻个蛋……继续填坑 Uncaught DOMException: Failed to execute 'toDataURL' on 'HTMLCanvasElement': Tainted canvases may not be exported 原因二：图片url缓存 在这里找到的方法： https://stackoverflow.com/questions/46609800/canvas

How to post immediately after svg to canvas conversion is done?

问题 I am attempting post with html2canvas after converting all the svgs in a html element to canvas, but the post executes immediately before the svg to canvas conversion finishes, since it takes a few seconds. I have tried using deferred and promises, but I am still having the same issue. // https://github.com/niklasvh/html2canvas/issues/95#issuecomment-45114424 // First render all SVGs to canvases targetElem = $('#dashboard'); var elements = targetElem.find('svg').map(function() { var svg = $
