LibreOffice Draw

LibreOffice is an integrated office suite based on copyleft licenses and compatible with most document formats and standards. Libreoffice is backed by The Document Foundation, which represents a large independent community of enterprises, developers and other volunteers moved by the common goal of bringing to the market the best software for personal productivity. LibreOffice is open source, and free to download, use and distribute. You can develop for LibreOffice in one of two ways, one recommended and one much less so. First the somewhat less recommended way: it is possible to use the SDK to develop an extension, for which you can read the API docs and Developers Guide. This re-uses the (extremely generic) UNO APIs that are also used by macro scripting in StarBasic. Java is required for building many parts of LibreOffice. In TDF Wiki article Development/Java, the exact modules that depend on Java are listed. The baseline for Java is Java Development Kit (JDK) Version 17 or later. The baseline for Python is version 3.11. It follows the version available in SUSE Linux Enterprise Desktop and the Maintenance Support version of Red Hat Enterprise Linux. If you want to use Clang with the LibreOffice compiler plugins, the minimal version of Clang is 18. Since Xcode doesn't provide the compiler plugin headers, you have to compile your own Clang to use them on macOS. To setup your initial build environment on Windows and macOS, we provide the LibreOffice Development Environment (LODE) scripts. For more information see the build instructions for your platform in the TDF wiki. Each module should have a README.md file inside it which has some degree of documentation for that module; patches are most welcome to improve those. We have those turned into a web page here: However, there are two hundred modules, many of them of only peripheral interest for a specialist audience. So - where is the good stuff, the code that is most useful. Here is a quick overview of the most important ones: basegfx/ algorithms and data-types for graphics as used in the canvas canvas/ new (UNO) canvas rendering model with various backends cppcanvas/ C++ helper classes for using the UNO canvas drawinglayer/ View code to render drawable objects and break them down into primitives we can render more easily. The UNO API include files should consistently use double quotes, for the benefit of external users of this API.
