Open Source Linux Graphic Design Software

Tux Paint is a free, award-winning drawing program originally created for children ages 3 to 12, but enjoyed by all! It combines an easy-to-use interface, fun sound effects, and an encouraging cartoon mascot who guides children as they use the program. You're presented with a blank canvas and a variety of drawing tools to help them be creative. Along with paintbrush, shapes and text, Tux Paint includes a "stamp" feature to add pre-drawn or photographic imagery to pictures, and a set of "magic tools" that provide filter effects (like blur, tint and waves) and interesting drawing tools (like train tracks, bubbles and grass). Tux Paint includes a collection of "starter" images, both coloring-book style and photo-realistic, and a large collections of stamps are available as a separate download. Additional content can be added by parents & teachers, or downloaded from 3rd parties. Tux Paint is available for Windows, macOS, Android, Linux, & Haiku operating systems, among others.

Xournal is a GTK+/Gnome application for notetaking, sketching, keeping a journal using a stylus on Tablet PCs and other platforms. It aims to provide superior graphical quality (subpixel resolution) and overall functionality.

qvge is a multiplatform graph editor written in C++/Qt. Its main goal is to make possible visually edit two-dimensional graphs in a simple and intuitive way. Please note that qvge is not a replacement for such a software like Gephi, Graphvis, Dot, yEd, Dia and so on. It is neither a tool for "big data analysis" nor a math application. It is really just a simple graph editor :)

NoteLab is an advanced "digital notebook" specifically designed for tablet computers. With its stroke smoothing, antialiasing, and "smart rendering," NoteLab provides a beautiful and powerful note taking environment on any operating system.

This project provides a tool to include in Inkscape. This tool gives to inkscape options to do easy 2D animations using the menu effects, and it's usefull to teach multimidia concepts to youngs and children. English version in march.

SGI allows to define and interpret most of undeterministic 2D shape grammars. It supports real-time subshape detection and labeled rules. GUI is designed for easy manipulation with shape grammars: creation of shapes, rules and generation of designs.

j2dcg: Java 2D Computer Graphics and Imaging Framework. This framework is targeted for academic use, to reduce the amount of Java / User Interface coding for assignements targeting both raster and vector graphics.

Un outil pour éditer des diagrammes Entité/Association sous Processing d'où son nom Editor of Entity/Relationship under PROcessing (2ERPro). L'outil est dans sa première version et loin d'être final. Il vise à démontrer les capacités de Processing plus qu'être éditeur dans le sens propre du terme.

Feel pictures free of charge - SeebyTouch is the unique open source tactile vision substitution system available! Using the software and the construction manual it is possible for everyone to get pictures over the tactile sense! - Blindensehersatzsys

The scope of the project is to establish a new architecture personal home pages are managed in the internet, thus the way the users would navigate them. The idea come from the new technology trends from internet. The key idea are compact, concrete, easy manage and loosely coupled structure (peer to peer). I will sketch out the technical detail in the wiki. And began to prototype it in my personal webpage.

Convey is a real-time, online, multi-user collaboration tool which augments text, graphics, and symbols. Examples of graphics include shapes, mathematical expressions, diagrams, flow charts, and pictures.

Euclide is a dynamic geometry application written in Java. It allows creation of geometric shapes (lines, points, circles, conics...) and transforms (rotation, symmetry...), which depend each other. Moving a shape will also move shapes dependent on it.

Is an algebraic-geometric program to make geometricals constructions; handle points, lines, conical, symmetries, invertion, locus, animation, etc.

GoGraph is a tutorial software giving informatics students an easy, interactive and ergonomic way to learn and exercise the graph theory. It is based on JGraph, an open-source graph component for Java.

Java editor for petri nets, based on the ARP analyzer. Exports nets to GIF, JPEG, PNG, PPM, ARP and PNML (XML based) file format. Uses the excellent JHotDraw 5.2 framework.

JDrafting is an open source Java application to create Technical Drawing exercises. This application is inspired by the 'Classical Construction', also known as 'Ruler-and-compass Construction' or 'Compass-and-straightedge construction'. However, another drawing tools can be used. (More info about classical construction: https://en.wikipedia.org/w/index.php?title=Compass-and-straightedge_construction) Download examples in 'Files tab' JRE 8+ needed Github: https://github.com/miguelalejandromorenobarrientos/jdrafting Android version (not compatible) https://sourceforge.net/projects/andrafting/

JShoe is a web based service that works as a complement for education. It's a tool that allows teachers to transmit the art and craft of shoe design.

Perl script for automatic distinct processing of LaTeX programmed inline drawings allows use of incompatible illustration tools in the same document and critically reduce recompilation time.

Meshgen is designed to interactively generate 2D FEM meshes composed of triangular and quadrilateral elements.

QTed (Questions and Tests editor) is a web-based editor that allows to create items and tests in agreement with standard IMS - QTI v2.1. and to maintain a personal repository (of items and tests) for each user.

SIP is the image processing and computer vision package for SciLab, a free Matlab-like programming environment. SIP reads/writes images in formats like JPEG, PNG, and BMP. It does filtering, segmentation, edge detection, morphology, and shape analysis. Download from Git http://siptoolbox.sourceforge.net/devel

Applications that use and display SignWriting symbols. Applications are based on a library of common operations instead of recreating the same logic for each app. The library is built on the portable wxWindows cross-platform application framework.

This application is a 3 dimensions object maker and viewer program. It creates 3D objects by a simple way. The made object viewable with 3D glass which has two different color glasses. The two colors of 3D image are settingable for the both glass-colors. The created object is walkable around, saveable, loadable back. The background color and object mono-color both are changeable. This application does not make surface on the object but makes a net by points. It is able to make a turning-object with a line along an axle in 2 dimension. When the line finished it turn that around of the axle and on this way it is making the 3D object.

Vectronics is a way to share schematics. It makes quick svg images that can be displayed in a browser and reopened and reedited as a schematic. Hyperlinks can also be added to link to data sheets or source code. It is a simple xml based drawing program .

Web 2.0 environment for collaborative and extensible design of object interconnection diagrams like UML, networks, circuits and other graph based diagrams. Client: Web-based (AJAX / Dojo Toolkit) Server: JEE Application (Struts Framework)
