Several of the most active contributors to OpenXmlDeveloper were in Redmond last week for the MVP Summit and an Open XML workshop, so Doug Mahugh interviewed them on some Open XML development topics. The videos are up on Channel 9 at the links included below.

Open-source Open XML API for Java
Julien Chable demonstrates his OPENXML4J project, which is a continuation of the work described in his article on OpenXmlDeveloper here.

Package Explorer for Open XML
Wouter Van Vugt talks about the latest release of his Package Explorer tool, which was originally covered on OpenXmlDeveloper here.

Linux/Java interoperability with Open XML
Sanjay Kumar and Datta Kulkarni of Sonata Software describe how Open XML can be used from a Linux environment, building on the techniques covered on OpenXmlDeveloper here.

Two New Articles

We have two new articles on the site today, both from Sanjay Kumar Madhva. Each covers a slightly different task related to Open XML programming, and each is implemented on a different development platform.

"Open XML Document Image Conversion" is the 3rd article in Sanjay's series on working with Open XML Formats in Java. It shows how to extract a large BMP image from a word processing document, convert it to a smaller PNG, and replace the larger image with the smaller one.

The original intent of this article was to demonstrate a technique for compressing a large document that is bloated with embedded BMPs, but to Sanjay's surprise he found that the ZIP compression of a typical BMP screen shot in an Open XML package is so good that there's not really any room for improvement via this technique. Nonetheless, this article is a good example of how to replace embedded media in an Open XML document for those working in Java environments.

The second article, "Creating an Open XML Document in .NET," takes a look at how to write user-entered text into a newly created Open XML document. It's a very simple starting point for such applications, showing the basics of how to generate an Open XML document from scratch using the new WinFX packaging API. Logical future extensions to this application would include using an RTF control and capturing more complex formatting, and implementing the same concepts in a web application.

Java code for common document management tasks

The guys at Sonata have submitted another instructive Java code sample. This one shows how to do some basic document management chores such as adding or removing parts from the Open XML Format package. It's packaged as a simple utility. Click here for the article and source code.
