Open Image Pipeline or OIP for short is a plugin based highly modular image processing program written entirely in C. OIP is designed around the concept of using plugins for image manipulation; no actual image manipulation code is included in the main OIP binary. The main objectives of Open Image Pipeline are to be fast and modular. Speed is achieved by using C as the programming language and by keeping optimization in mind while programming. Modularity on the other hand is achieved by the use of plugins.
NOTE: This program is still under VERY heavy development. It probably doesn't work correctly yet and is full of bugs etc. Do not use it for anything important. The most stable branch right now is master, which I try to keep compilable. However, I can't guarantee the master branch will work correctly either.
Open Image Pipeline currently only has a text based command line interface, however, a GUI based interface will probably be implemented later. The only operating system where Open Image Pipeline currently works is Linux and even there it requires quite a bit of computer knowledge to be able to run the program. If you still want to give it a try, check out the Compiling section below.
Below is a list of links to the plugins I have programmed for OIP. Currently
the only way to use them is to compile them yourself and place them in the
plugins directory of OIP (or use the install target of the plugin's makefile).

FreeImage 3
Open Image Pipeline currently only works on Linux. The steps to compiling OIP are listed below.
-
Install FreeImage and the FreeImage development files. On Debian Jessie this can be accomplished by running
sudo apt-get install libfreeimage3 libfreeimage-dev. -
Compile the Open Image Pipeline Core by running
make oipcore. -
[Optional] Compile the Open Image Pipeline submodules by running
make oipmodules. These modules are only needed if you intend to develop and compile plugins. -
[Optional] Compile the Open Image Pipeline Shell by running
make oipshell. This part is technically optional, however, the OIP Shell is currently the only way to use Open Image Pipeline apart from directly using it from the C language. The compiled binary is placed into the foldersrc/oipshell/bin/. -
Obtain source code for plugins and compile them yourself or obtain the plugin binaries directly. For now you most likely need to compile the plugins yourself, so remember to follow the instructions in step 3. first and then follow the compilation instructions of the plugins.
-
Place the plugin libraries into the
pluginsfolder in the main Open Image Pipeline directory. -
Add the path to the OIP Core shared library to your library search path by running
export LD_LIBRARY_PATH=<PATH_TO_OIP_DIR>/src/oipcore/oipcore/bin. You must run this after every reboot if you want to use OIP since the setting resets every time the computer is restarted. Alternatively you can try to find a more permanent way of adding the path to the library search path yourself. -
Now you're ready to use Open Image Pipeline by using the OIP Shell or by calling functions from the C language.
You can also compile every part of Open Image Pipeline by just running
make all. By passing DEBUG=1 with the make command you can enable
debug information genration and a memory address sanitizer while compiling.
Note that you won't be able to use non-debug builds of plugins with a
debug build of Open Image Pipeline and vice versa.
The makefile has the following additional targets
Delete all the files created by the compilation including the files created when compiling the modules.
