uma::bson is a DOM-style C++ API for reading/writing BSON data. Unlike the MongoDB C++ API, which exposes a read-only interface with a separate interface for creating a BSON representation, this API allows reading/writing on the existing data. The API is designed primarily for serialising/deserialising BSON data to/from streams (files, socket connections, etc.).
BSF4ooRexx is a Java language binding for the scripting language ooRexx. It allows ooRexx programmers to directly use the Java Runtime Environment (JRE) libraries. It allows, for example, implementation of Java methods in ooRexx and callbacks from Java to ooRexx. It camouflages Java so that it resembles ooRexx by being dynamically typed and caseless. BSF4ooRexx comes with built-in support for programming OpenOffice.org/LibreOffice.org and allows ooRexx to be used as a macro language.
The Hummus PDF Writer library allows you to generate PDF files. It was developed with a principal “one-off” method of generating PDF files. Adhering to this idea, it is both fast and retains a low memory signature regardless of how large the file grows. The library has a set of high level features for adding content to a PDF, including creation of pages; drawing primitives and any of the simple PDF operators for drawing content; embedding of PDF, JPEG, and TIFF images; Unicode text support with Type1, TrueType, and OpenType fonts; and defining reusable objects using XObject Forms. You can also use the library as a PDF parser. The library is very extensible. It is easy to implement more PDF features by using the lower level set of methods, which provide access to the PDF building blocks themselves. Adding a feature requires you to be familiar with the PDF formatting of that feature, but will not require you to write the basic PDF building blocks, as the library handles this.
