具有外部托管图像的 Pixastic
我正在使用 Vimeo API 获取视频缩略图，我想使用 Pixastic 将效果应用到这些视频。但是，在 Chrome 和 Safari 中，我收到错误消息：“未捕获的错误：SECURITY_ERR：DOM 异常 18”。我尝试将外部图像绘制到画布元素，然后将 Pixastic 效果应用到这些画布元素，但我收到相同的错误消息。
有人在 Webkit 中成功使用 Pixastic 与外部图像吗？
I am using the Vimeo API to get thumbnails of videos which I would like to apply effects to using Pixastic. However, in Chrome and Safari I get the error message: "Uncaught Error: SECURITY_ERR: DOM Exception 18". I have tried drawing the external images to canvas elements and then applying the Pixastic effects to those canvas elements but I get the same error message.
Is anyone successfully using Pixastic with external images in Webkit?

我也遇到了这个问题，只是我没有意识到我的问题是外部图像。从绝对链接更改为根相对链接对我有用。
由于画布安全限制，Pixastic 无法处理外部图像。解决这个问题的方法是创建一个代理来提供外部图像，就好像它们是本地图像一样，否则您将必须复制图像。
I ran into this problem too, only I didn't realize my problem was external images. Changing from absolute to root relative links worked for me.
Pixastic can't work on external images due to a canvas security limitation. The way around this is to either create a proxy to serve the external images as if they were local, or you will have to copy the images.
