SecurityError when using Data URIs css backgrounds on iOS 10+ Safari/Chrome
See original GitHub issueHello,
It seems on iOS 10.3+ html2canvas throws errors when calling ctx.toDataURL() if the page contains any inlined images css background using data URIs.
Error : SecurityError (Dom Exception 18). The operation is unsecure.
To reproduce : https://jsfiddle.net/es26hhdx/
It seems to work ok in iOS 9 and android, only safari and chrome mobile on iOS 10 are affected with the problem so far.
It is weird that those local css background data - URIs cause CORS issues as i would think they are used by the lib as local images.
Could you guys think of any workaround (apart from not using data URIs) ?
thanks

The main problem is if you have driven the image from css class. example : background: url(“…/assets/images/”).
Remove this reference and add it as image tag in the html it will work
