We have been publishing a series of articles entitled Understanding the PDF file format. In each article we try to take a specific PDF feature and explain it in simple terms. You can see all the articles so far here.
If you have any suggestions or items, you would like to see, contact us.
IDRsolutions develop a Java PDF Viewer and SDK, an Adobe forms to HTML5 forms converter, a PDF to HTML5 converter and a Java ImageIO replacement. On the blog our team post anything interesting they learn about.
