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


function CreatePDF(IsInternetExplorer8OrLower) {

    // create BytescoutPDF object instance
    var pdf = new BytescoutPDF();
    // set document properties: Title, subject, keywords, author name and creator name
    pdf.propertiesSet("Sample document title", "Sample subject", "keyword1, keyword 2, keyword3", "Document Author Name", "Document Creator Name");
    
    // add header for all pages
    pdf.onHeader(function() { pdf.textAdd(10, 20, '<font size="15">Page ' + pdf.pageGetIndex() + ' </font>'); } );
    
    // add footer for all pages
    pdf.onFooter(function() { pdf.textAdd(250, 820, 'page ' + pdf.pageGetIndex() + ' of ' + pdf.pageGetCount()); } );
