Strange sIFR / screen-reader bug
I was writing a little accessibility article for .net magazine about text-replacement techniques, including sIFR. I was blithely saying that “yea, don’t worry, it’s fine” with a couple of caveats. But, rather than rely on memory I did a quick test, and discovered something strange.
Adobe open Flash
The Open Screen Project
from Adobe will remove restrictions on use of the SWF and FLV/F4V specs, and removing the licensing fees. What could the consequences be?
Comparing Tagged PDFs from Office and Acrobat
After my initial disappointment with the Office 2007 pluggin for creating PDFs, I’ve had some discussion with the Microsoft team, and a chance to do a bit more testing. This post compares the conversion of a simple Word 2007 document with the Office pluggin, Acrobat 8.1, and OpenOffice.
Colour Contrast Visualiser – New Tool
A friend & colleague of mine has just released the beta version of a new tool. Although everyone (who cares) has probably heard of colour contrast analysers, this does the opposite, and helps you choose accessible colour combinations.

Office 2007 PDFs – Not (always) accessible
I had previously heard that Office 2007 (or 12 back then) was going to have built in PDF support, with tagging (i.e. accessible output). Not too long ago I installed Vista and Office 2007 on my work machine, but there was no sign of it. Then I found the Microsoft Save as PDF or XPS Add-in for 2007 Microsoft Office

CMS editable Flash
With all the fuss over AJAX and Flash accessibility you get, I thought it might be worth outlining the process we used to create a Flash/AJAX widget and highlight one of the advantages you get with this method. It also means that the use of Flash has no impact on your Search Engine Optimisation.
Note on Non-HTML formats
In my previous article on responsibilities in accessibility you might have noticed that I’d fallen into the traditional accessibility trap of only really referring to (X)HTML/CSS sites and guidelines. I’m quite aware of other technologies, but it’s worth looking at why other formats are harder to make accessible.
Automated PDF accessibility testing
I periodically receive emails from Sitemorse, despite trying to unsubscribe a couple of years ago. This one escaped my usual filters, and I noticed an interesting statistic about the number of accessible PDFs in the wild.
The four levels of PDF accessibility
Portable Document Format (PDF) accessibllity is not a new topic, it is well understood and explained by certain experts. However, the implications are universally unknown by organisations.
