Your question is not very clear. Perhaps if you provided a jsfiddle illustrating it, or eve just some code with images of what you're expecting versus what you're getting, you may get more lucky with an answer. On Wed, 17 May 2017 at 09:37, cheng notifications@github.com wrote:

I believe you are talking about cross-domain images. For Internet security reasons, trying to use an image from a different domain in a canvas causes problems. There are two html2canvas options, useCORS and proxy, which are designed to try to get around that problem. They're not perfect solutions though - you can read more over at #951 and #592.
