Proxy user guide

Hello,

Could you provide us a guide on how to use this proxy with html2canvas.
On localhost the canvas generation works fine, however when uploaded to the server, I'm facing the error : Unable to get image data from canvas because the canvas has been tainted by cross-origin data.

Thanks in advance.

Problems

I created a google app using the open source code and deployed it. I changed the proxy addresses in the jquery.plugin.html2canvas.js and screenshots.html. Then I tried to run screenshots.html, but it didn't work. Is there something else I should be doing?

Facebook comments

I have a website witch uses facebook plugin comments. I'm looking for a way to have those comments inside a screenshot. If I use the simple html2canvas I get a blank box instead of them. So I try to use html2canvasproxy but now it print some javascript console log instead of the facebook comments.
It shoud be like www.peoplesecrets.com/screenshots/1.png but I get www.peoplesecrets.com/screenshots/2.png . I noticed that the html2canvasproxy.php saves the facebook plugin html correctly. How can I solve?

Flex is not supported

I am implementing screenshot widget on top of html2canvas functionality. I am running into an issue as the markup has used flex extensively and seems that html2canvas module is not supporting flex. So, need help here regarding how to add support for flex while taking screenshot using html2canvas

Support for redirected images

Example, show Facebook profile images:

https://graph.facebook.com/1415773021975267/picture
becomes:
https://fbcdn-profile-a.akamaihd.net/hprofile-ak-ash1/276836_1415773021975267_370639944_q.jpg

I'm looking at this, but hopefully I will use a hack in my code... Anyone had the same issue?

Proxy doesn't work on a load balanced setup

Hello,

I'm trying to use the html2canvas proxy on a load balanced setup. But for some reason I keep seeing the following error in my console:

GET http://mydomain.com:8080/screen-shot-scripts/images/h2c_f2e33735cc8f9b3feef65e52f35c3d3cab032349.jpg net::ERR_CONNECTION_REFUSED

Why is this giving me this error?

Thanks

Please make a fast solution. I have to launch the site soon.
Thanks

How do I use html2canvas proxy

Hey,

So in html2canvas.js i set

            // preload options
            proxy: 'proxy.js',
            timeout: 0,    // no timeout
            useCORS: false, // try to load images as CORS (where available), before falling back to proxy
            allowTaint: false, //

And in proxy.js (node.js proxy) What do I set here

var url, http, request;
url = require('url');
http = require('http');
request = require('request');

I am running on my local host and I am using html2canvas to capture cross-domain homepage screenshots.

I keep getting this error

html2canvas.js:359
2
Blocked a frame with origin "http://localhost" from accessing a frame with origin "http://money.rediff.com". Protocols, domains, and ports must match. html2canvas.js:359
Uncaught ReferenceError: require is not defined proxy.js:10

Please help.

html2canvas OnRender failed because of cross domain images

I want a screenshot of the current page through html2canvas. However, the code displays "here" and then stops the second alert function is not triggering

alert("here");
html2canvas(instance.element, {
    onrendered: function(canvas) {
        alert("here");
        instance.options.onPostRender(canvas)

In the firebug the following error appears:

"NetworkError: 404 Not Found - http://html2canvas.appspot.com/?url=https%3A%2F%2Fwww.otherdomain.com%2Flivezilla%2Fimage.php%3Fid%3D08&callback=html2canvas_1"
"NetworkError: 404 Not Found - http://html2canvas.appspot.com/?url=https%3A%2F%2Ffpdbs.sandbox.paypal.com%2Fdynamicimageweb%3Fcmd%3D_dynamic-image%26buttontype%3Decshortcut%26locale%3Den_US%26ordertotal%3D569.00%26pal%3D3JZ6HTBQ33JC2&callback=html2canvas_8"

I think its because the image is from another domain, but I found related issue but I think the proxy is already there now.
