// function that creates BytescoutPDF instance (defined in BytescoutPDF.js script which have to be included into the same page) // then calls API methods and properties to create PDF document // and returns created BytescoutPDF object instance // this CreatePDF() function is called from Sample.html // IsInternetExplorer8OrLower parameter indicates if we use IE8 or lower so we CAN'T use images (as it requires HTML5 Canvas available in IE9 or higher).
