The ability to search documents, include digitial signatures and reduced file size is resulting in both Governments and corporations adopting the PDF/A standard.<p><a href="http://bfo.com/blog/2011/09/29/pdf_a_standard_long_term_archiving_solutions.html">Read more...</a></p> http://bfo.com/blog/2011/08/25/using_acrobat_javascript.html PDF documents can contain JavaScript, which opens up all sorts of possibilities - not all of which are gaping security holes. Here's an article showing how to use it in PDF - both how to embed it from the Report Generator, and how to run it in the Viewer.<p><a href="http://bfo.com/blog/2011/08/25/using_acrobat_javascript.html">Read more...</a></p> http://bfo.com/blog/2011/08/10/yet_another_happy_bfo_pdf_library_customer.html QNT Systemy Informatyczne is a leading manufacturer of software for government organizations in Poland.

Our PDF Library has been able to digitally sign documents for years, but digitally signing a file with a key that's trusted by Acrobat is a little trickier, and requires hardware.

This release offers improvements in memory and speed across the board, with tweaks to the low level data-structures that underly all PDFs. The Jar has shrunk by 10% as well, and our packed <a href="/products/pdfviewer/example.jsp">PDF Viewer Applet</a> now scrapes in at just under 800KB.<p><a href="http://bfo.com/blog/2011/03/31/smaller_faster_better_bfo_release_new_pdf_library.html">Read more...</a></p> http://bfo.com/blog/2011/03/08/odds_and_ends_creating_a_new_x_509_certificate.html A quick tip completely unrelated to PDF or Graphs: How to create a new self-signed X.509 Certificate with Java.<p><a href="http://bfo.com/blog/2011/03/08/odds_and_ends_creating_a_new_x_509_certificate.html">Read more...</a></p> http://bfo.com/blog/2011/02/23/emotion_timewave_search_engine_set_to_use_bfo_graph_library.html A computer scientist from Bath University is creating an Intelligent Digital-Emotion Analyser Library (iDEA) with functionality from the <a href="/products/graph/"> BFO Graph Library</a><p><a href="http://bfo.com/blog/2011/02/23/emotion_timewave_search_engine_set_to_use_bfo_graph_library.html">Read more...</a></p> http://bfo.com/blog/2010/11/24/bfo_release_pdf_library_and_pdf_viewer_update.html Version 2.11.12 of the PDF Library and PDF Viewer fixes a small memory leak in the Viewer which could occur during text selection. Some new methods for working with the Adobe Highlight File Format have been included, along with a large number of minor bugfixes and improvements since the previous release in June.<<p><a href="http://bfo.com/blog/2010/11/24/bfo_release_pdf_library_and_pdf_viewer_update.html">Read more...</a></p> http://bfo.com/blog/2010/09/23/trimming_whitespace_from_a_tiff_before_saving.html Sometimes when you convert a PDF to TIFF, you're left with a lot of whitespace around the content of the page.

The XML is much easier to work with, but there are always situations where you'll need the flexibility of the API. Here we show you how to do this, and we also present a neat and non-obvious technique for watermarking.<p><a href="http://bfo.com/blog/2010/08/03/watermarking_a_report.html">Read more...</a></p> http://bfo.com/blog/2010/05/13/combining_ant_jar_signatures_and_pack200.html If you're deploying Java code as Applets, Pack 200 compression can reduce the size of your download by 70%.

However this isn't the only way to do it. Both Acrobat and our PDF viewer allow a PDF to be decrypted using a private key which is specific to a user. In this article we show you how to create a key, encrypt a document for that key and then decrypt it again.<p><a href="http://bfo.com/blog/2009/11/12/public_key_encryption_and_pdf.html">Read more...</a></p> http://bfo.com/blog/2009/11/05/graphs_in_dynamic_web_pages.html The traditional approach to using the BFO Graph Library in web pages has been to use the JSP tag library so that the server processes XML in JSP pages and replaces it with generated graphs. <br /> <br /> However if you want to include BFO graphs in non JSP web pages that use AJAX to load data dynamically then the tag library is not very useful. Although the Graph Library has a SOAP interface for web service access SOAP is not well suited to being used from web pages, so instead we will use the plain XML interface to the Graph Library to dynamically add charts to web pages.<p><a href="http://bfo.com/blog/2009/11/05/graphs_in_dynamic_web_pages.html">Read more...</a></p> http://bfo.com/blog/2009/10/07/qr_code_and_other_barcodes.html The PDF Library supports a large number of barcodes, including QR-Code.
