Testing_Selenium::captureEntirePageScreenshotToString

Downloads a screenshot of the browser current window canvas to a based 64 encoded PNG file. The <i>entire</i> windows canvas is captured, including parts rendered outside of the current view port.

Currently this only works in Mozilla and when running in chrome mode.

Signature

public function captureEntirePageScreenshotToString(string $kwargs )

Parameters

$kwargs

A kwargs string that modifies the way the screenshot is captured. Example: "background=#CCFFDD". This may be useful to set for capturing screenshots of less-than-ideal layouts, for example where absolute positioning causes the calculation of the canvas dimension to fail and a black background is exposed (possibly obscuring black text).

Returns

string

The base 64 encoded string of the page screenshot (PNG file)
