Take Screenshot

Selenium Nodes for KNIME version 4.7.1.202102162139 by seleniumnodes.com

Take a screenshot of the currently loaded page in the selected WebDriver, or a specified WebElement. The WebDriver respective WebElement must support taking screenshots, else an error is triggered (e.g. the HtmlUnitDriver does not allow to take screenshot, as it is not running within a GUI). The extent of the resulting screenshot depends on the actual WebDriver (some WebDrivers capture the entire page, or the current window, or the visible frame, or the entire screen).

Quoting from the Selenium API documentation:

For WebDriver […], this makes a best effort depending on the browser to return the following in order of preference:

  • Entire page
  • Current window
  • Visible portion of the current frame

For WebElement […], this makes a best effort depending on the browser to return the following in order of preference:

  • The entire content of the HTML element
  • The visible portion of the HTML element
