5 apps to debug PDF files
April 13th, 2016
Very often we encounter PDF files that cannot be loaded or are not displayed correctly. Or they can be loaded with Adobe Reader (which is very forgiving when it comes to PDF errors) but they cannot be loaded with another tool and the customer asks 'Why?'. To debug PDF problems like these we need to dig deep in the PDF file structure.
In this article you'll find 5 applications for inspecting PDF files down to the COS object level. These tools require knowledge of PDF specification in order to understand their output. All the applications run on Windows and are GUI based.

IFXPDFFactory 0.1.0 Alpha version now available
November 15th, 2013
First version of IFXPDFFactory for iOS is now available. It's an alpha version which means it has bugs and only the basic features are implemented but it lets you feel the API and test the concepts shown in the articles published so far.
There are 14 samples included in the samples browser application to show the features implemented so far. There is no Apple style documentation yet, but it will come.
Feel free to download the framework and take it for a test drive. Any questions you might have can be posted here as comments or sent by email to me.

The supported fonts are: Helvetica, Helvetica Bold, Helvetica Italic, Helvetica Bold-Italic, Courier, Courier Bold, Courier Italic, Courier Bold-Italic, Times Roman, Times Roman Bold, Times Roman Italic, Times Roman Bold-Italic, ZapfDingbats and Symbol.
