Open the page you would like to capture:
Use the "JavascriptExecute" command to automate the scrolling of the webpage to find the true width:
width = WebExecute[session, "JavascriptExecute" -> "return document.documentElement.scrollWidth"]Use the "JavascriptExecute" command to automate the scrolling of the webpage to find the true height:
height = WebExecute[session, "JavascriptExecute" -> "return document.documentElement.scrollHeight"]Use the "SetWindowSize" command to set the current window size to be the actual width and height of the webpage:
WebExecute[session, "SetWindowSize" -> {width, height}]- The preceding JavaScript works with both the HTML body margins and the margins of content within the body tag, pushing it downward.
