Sven Neumann February 2003 This document outlines the directory structure of the GIMP source tree. It should help people to get started with the GIMP code. The GIMP source tree can be divided into the core application, libraries, plug-ins, data files and some stuff that doesn't fit into these catagories. Here is a list of top-level directories: app the application The contents of these directories will be explained in detail in the following sections. The source code of the core GIMP application is found in the app directory. app/arch architecture specific code app/arch/i386 Intel 386 specific code app/arch/i386/mmx MMX code for the Intel 386 processor family app/base base functionality such as pixel regions, tiles etc. app/paint-funcs functions to manipulate pixels, part of the base functionality, uses code from the arch directory app/config handling of config files, provides the GimpConfig interface and the GimpRc object which is used from all over of the application. Depends on GObject app/core the core of the GIMP core, makes heavy use of GObject but is not GTK+-dependant. app/file file handling routines, part of the core app/paint paint core that provides different ways to paint strokes app/plug-in plug-in handling, part of the core app/pdb core side of the Procedural Database, exposes internal functionality by means of the PDB app/text text handling, part of the core app/vectors vectors framework, part of the core app/xcf XCF file handling, part of the core app/display handles displays (e.g. image windows), part of the GUI app/tools user interface part of the tools as found in the toolbox. The actual tool functionality is in the core app/widgets a collection of widgets used in the application GUI app/gui he code that puts the user interface together
