If there is a key called 'BaseFont', that is a font that is used in the document.
If there is a key called 'FontName' and another key in the same dictionary object
that is called 'FontFilex' (where x is null, 2, or 3), then that fontname is
embedded.

javascript: is element inside an iframe visible within the viewport?
// Given an iframe id and an anchor id that is present within the iframe,
// determine whether the element is visible/present inside the window viewport.
// This is not about the css 'display' property; this shows whether
// the window viewport contains the element.
var isVisible = function (anchor, iframe_id) {
var ifrId = iframe_id || 'bv_page';
var ifrOffset = window.parent.document.getElementById(ifrId).offsetTop;
var myloc = document.getElementById(anchor).offsetTop + ifrOffset;

Use in conjunction with mathjax_test.js script; all this does is load the page so any errors flagged from the mathjax_test code is posted to the error database. the two scripts need each other in order to test the file. This script expects a single…

MathJax testing for TeX and rendering errors. Create HTML page (with math) to include the MathJax library and then include this file. When the page is loaded, the js console will show when errors are encountered and the data about the error will be POSTed via ajax to a rest-type service named here as 'service/mathmltest'. That service should acc…
