We’re busy getting ready for the PDF Technical Conference coming up next month in San Jose, CA! Those who are near the Bay Area and who are interested in PDFs or document workflows should sign up for two days of informative talks, both theoretical as well as practical. Seasoned practitioners who mumble PDF syntax in their sleep, as well as those who are interested in learning more about how PDFs help solve complex business problems, are all welcome.
Sample of the Week:
Adobe Acrobat DC makes the act of signing PDF files ridiculously simple; it’s at the point now where all you need is Adobe Reader and either your finger or a mouse. But signing PDF can be tricky. This article is not intended to dissuade you from using PDF files for signing documents, quite the opposite. The intention is to help developers to add the necessary attributes to the PDF to make the document reliable for signing and to ensure that all parties involved understand what is being agreed to. The issue is that the PDF language provides a number of capabilities that can make the rendered appearance of a PDF document vary even in the same version of Acrobat but on different machines. These capabilities could potentially be used to construct a document that misleads the recipient of a document and are relevant when considering the legal implications of a signed PDF. The most obvious of these capabilities is the layers feature but can be as esoteric as not embedding a font; remember, there are PDF files out there that were created before the invention of the Euro symbol.

We have kept the support for Android 2.x versions up until now since we want to support a wide range of devices for our users around the world. However with the prevalent number of devices that are running Android 4.x and higher now , we want to be able to support the new way of interacting with menus and options, especially on a large number of devices that use soft menu buttons. To take advantage of the new UI features, means that we need to move to support Android 4.0 and up.
Sample of the Week:
Over the last few weeks, I’ve published articles describing how to populate PDF forms from a SQL database. Until now, we’ve just been adding data to existing fields. This week I show how to handle calculated fields in the PDF file that may not have a corollary in the database and how to deal with fields that may be formatted differently than the data that represents their value.
Unlike any other PDF SDK or library that I’ve come across, the Datalogics PDF Java Toolkit, will allow the developer to run the calculations in calculated fields the same way that Acrobat does. This means that your server application doesn’t need to know how to calculate the value of a field in your PDF file that may be dependent on other field values. It just works. The same is true with formatting scripts. Continue reading
