Hi,

In Google Chrome the ''chrome.tabs.captureVisibleTab(integer windowId, function callback)'' method will return a data URL of the JPEG encoding of the visible area of the captured tab.

We want to save that content as image to hard disk without opening/passing the contents into new html page.

Does anybody know how it can be done by javascript.

Please provide help.
Thanks.
