PDF In-Depth

Latest PDF Standards

Years ago (and years!) when we used to talk about PDF as being the most prominent document format, we'd always have to add a quick, under-the-breath, "de-facto standard". But when it came to being 100 percent assured that it would be around in years to come, it's always been a case of biting our collective lips and hoping for the best. What we would do if Adobe pulled the plug? Over the past two years, though, it's been nothing but standards, standards, standards when it comes to PDF. In fact, there are so many that it's easy to lose track. In this feature article, Planet PDF Editor Karl De Abrew helps to de-mystify the ever-increasing range of PDF-based standards.
