This feature allows you to cope with web pages that animate.
Most web pages simply load and complete. However some web pages
may not complete in a simple manner. For example graphs may draw
themselves, maps may update, images may move. These are all
features associated with more dynamic modern HTML and AJAX based
To cope with this we introduce the concept of a RepaintDelay and
When the page has finished loading we wait to see what drawing
occurs. Each time the page updates - drawing occurs - we set a
timer back to zero.
If the timer reaches the RepaintDelay limit then we assume that
the page has reached a ready state. At that point we convert it to
If the total time exceeds the RepaintTimeout we assume that the
page is never going to reach a ready state. At that point we
convert whatever we have to PDF.
This value is measured in milliseconds.
