This example demonstrates you can use Rich Text Editor to create industry standard PDF files on the fly. In the following example, we create a 0x0 size editor which will be used to convert Html to PDF.
<link rel="stylesheet" href="/richtexteditor/rte_theme_default.css" />
<script type="text/javascript" src="/richtexteditor/rte.js"></script>
<script type="text/javascript" src='/richtexteditor/plugins/all_plugins.js'></script>
<div id="div_editor1" style="min-width:0; min-height:0; max-width:0; max-height:0; overflow: hidden;"></div>
<button class="btn btn-sm btn-primary transition-3d-hover" onclick="downloadPDFDialog()">
Check the PDF file
</button>
<script>
var editor1cfg = {}
var editor1 = new RichTextEditor("#div_editor1", editor1cfg);
function downloadPDFDialog() {
editor1.setHTMLCode("<p>Hello World</p>")
editor1.execCommand("html2pdf");
}
</script>
