Creates a data URI encoding an image of the visible area of the currently active tab in the specified window. You must have the <all_urls> permission to use this method. (Alternately, Chrome allows use of this method with the activeTab permission and a qualifying user gesture).
This is an asynchronous function that returns a Promise.
Syntax
var capturing = browser.tabs.captureVisibleTab( windowId, // optional integer options // optional extensionTypes.ImageDetails )
Parameters
windowIdOptionalinteger. The target window. Defaults to the current window.optionsOptionalextensionTypes.ImageDetails.
Return value
A Promise that will be fulfilled with a data URL which encodes an image of the visible area of the captured tab. May be assigned to the 'src' property of an HTML Image element for display. If any error occurs the promise will be rejected with an error message.
Examples
Capture an image of the active tab in the current window, with default settings:
function onCaptured(imageUri) {
console.log(imageUri);
}
function onError(error) {
console.log(`Error: ${error}`);
}
browser.browserAction.onClicked.addListener(function() {
var capturing = browser.tabs.captureVisibleTab();
capturing.then(onCaptured, onError);
});
