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 new page pdf.pageAdd(); // draw formatted text pdf.textAdd(20, 50, 'You can use HTML tags for text formatting: &lt;b&gt; for <b>bold</b> and &lt;i&gt; for <i>italic</i> or &lt;s&gt; for <s>striked style</s>.'); // draw formatted text pdf.textAdd(10, 100, 'You may also change <font face="Helvetica" size="20" color="#0000ff">font size and</font> <font face="Courier" size="20" color="#ff0000">color</font> and use <u><b>mixed <i>styles</i></b></u>.'); // draw formatted text pdf.textAdd(10, 140, 'Zapf-Dingbats and Symbol fonts:'); // set zapf dingbats built in font to use pdf.fontSetName("zapfDingbats"); pdf.fontSetSize(25); // draw symbols, see map of letters to symbols at https://images.google.com/?q=zapf+dingbats+font+symbols pdf.textSetBox(10,150,500,300); // define output rectangle pdf.textAddToBox("1234567890!@#$%^&*()ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz") // set symbol font pdf.fontSetName("Symbol"); pdf.fontSetSize(25); // draw symbols, see map of letters to symbols at https://images.google.com/?q=zapf+dingbats+font+symbols pdf.textSetBox(10,310,500,800); // define output rectangle pdf.textAddToBox("1234567890!@#$%^&*()ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz") // return BytescoutPDF object instance return pdf; }
