createpdf.js

      // 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). Other browsers should be working fine

// IMPORTANT ABOUT IMAGES: 
// When using Firefox or IE, pdf generation may fail because images are not accessible when pdf generation works
// the solution for this issue is to preload images in main HTML document before running PDF generation
// to preload images, put them into hidden div block "pdfreportimages" - you can see it in the sample.html right after <body> opening tag
