FidoCadJ is a very easy-to-use editor, with a large library of electrical symbols and footprints (through hole and SMD). Drawings can be exported in several graphic formats (PDF, EPS, PGF for LaTeX, SVG, PNG, and JPEG). Although very simple and not relying on any netlist concept, FidoCadJ uses a file format containing only UTF-8 text, very compact and suited for copying and pasting with newsgroups and forum messages. This determined its success, being apt for simple mechanical drawings as well a
SDL_bgi is a graphics library based on SDL2. SDL_bgi is nearly fully compatible with BGI (graphics.h), the Borland Graphics Interface that was the de-facto standard in PC graphics back in DOS days. It's very easy to use, pretty fast, and it also provides extensions for ARGB colours, mouse support, and turtle graphics. It should run on any platform supported by SDL2.

Image processing is multi-threaded using O
Frei0r is a minimalistic plugin API for video effects. The main emphasis is on simplicity for an API that rounds up the most common video effects into simple filters, sources and mixers that can be controlled by parameters. Thanks to the frei0r collection more than a 100 effects can be shared by any application, avoiding duplicate efforts.
Full color painting software for Linux for illustration drawing. This is not suitable for dot editing. Since the color is handled with 16 bit color (15 bit fixed point number) internally, the accuracy of color rises, but the memory is consumed correspondingly.
Alembic is an open computer graphics interchange framework. Alembic distills complex, animated scenes into a non-procedural, application-independent set of baked geometric results. This �distillation' of scenes into baked geometry is exactly analogous to the distillation of lighting and rendering scenes into rendered image data. Alembic is focused on efficiently storing the computed results of complex procedural geometric constructions. It is very specifically NOT concerned with storing the comp

shufti is a lightweight, PyQt-based image viewer that non-destructively saves and restores the zoom level, rotation, window size, desktop location and viewing area on a per-image/file location basis.
OpenCSG is a library that does image-based CSG rendering using OpenGL. CSG is short for "constructive solid geometry" and represents a modeling technique for composing shapes with 3D-primitives which are combined using volumetric boolean operations. Image-based CSG rendering means rendering CSG shapes without calculating their surface in object-space. Instead, the image of a CSG shape is composed directly in the frame-buffer of the graphics hardware by rather sophisticated stenciling and z-buff
