- Gpaint is a small, easy-to-use paint program for GNOME. It features drawing tools (ovals, freehand, polygon, and text, with fill or shallow for polygons and closed freehand), the ability to cut and paste by selecting irregular regions or polygons, print support using gnome-print, a modern, easy-to-use user interface with tool and color palettes, the ability to edit multiple images at the same time with running multiple sessions of gpaint, and all the image processing features present in xpaint.
- GSEGrafix is an application which produces high-quality graphical plots for science and engineering. Plots are specified via simple ASCII parameter files and data files and are presented in an anti-aliased GNOME canvas. The program supports rectangular two-dimensional plots, histograms, polar-axis plots and three-dimensional plots. Plots can be printed or saved to BMP, JPEG or PNG image formats. GSEGrafix can also be run both from a command prompt and from Octave.
- KiCad is electronic design automation (EDA) software made for designing schematics of electronic circuits and printed circuit boards (PCB). KiCad is developed by the KiCad Developers Team, and features an integrated environment with schematic capture, bill of materials list, PCB layout and much more. KiCad is cross-platform, written with WxWidgets and runs on FreeBSD, Linux, Microsoft Windows and Mac OS X. A lot of component libraries are available. Also migrating tools for components are available (from other EDA software tools). File formats are plain text and well documented, which is good for CVS or Subversion and to make automated component generation scripts. Multiple languages are supported, such as English, Portuguese, Spanish, Czech, Polish, French, German, and Russian. The 3D PCB viewer use 3D model from Wings3D CAD.
- 'KolourPaint' is an easy-to-use paint program for KDE. Features include undo/redo, more than a dozen tools, selections, transparent image editing and zoom support (with an optional grid and thumbnail).
- Krita is a digital painting application for creating art from start to finish, suitable for concept art, texture, matte painting, illustrations and comics.
Krita is primarily designed for free-hand drawing purpose. It has an extensive, highly-customizable brush engine and a sophisticated layer system. It allows non-destructive image editing through transparency / transformation / filter masks. It supports raster graphics, SVG vector graphics and frame-based animation. The application supports full color management and it can handle HDR image editing and proofing. It has an intuitive, non-intrusive UI design. It is optimized for multi-core CPUs and uses OpenGL for canvas acceleration and display enhancements.
Krita is a cross-platform application. It supports Windows, Linux and Mac OSX.
Krita is written in C++, based on KDE Framworks and Qt, supports Python scripting extensions.

- 'mtPaint' is a simple GTK+1/2 painting program designed for creating icons and pixel-based artwork. It can edit indexed palette or 24 bit RGB images and offers basic painting and palette manipulation tools. Its main file format is PNG, although it can also handle JPEG, GIF, TIFF, BMP, XPM, and XBM files. Features include the ability to protect certain colours on the canvas from being painted over, up to 100 undo levels, a multiple image clipboard, the ability to view images between 10% and 2000% of their original size, and Spanish and Czech translations.
- MyPaint features:
- drawing program
- pressure sensitivity for graphic tablets
- brush dynamics (changes with speed, pressure, randomly)
- quick color changer
- infinte canvas
- no undo
- no layers
- using pygtk with C extensions
- Nomacs - Image Lounge
- nomacs is a free image viewer for windows, linux, and mac systems, which is licensed under the GNU General Public License v3. nomacs is small, fast and able to handle the most common image formats including RAW images. Additionally it is possible to synchronize multiple viewers. A synchronization of viewers running on the same computer or via LAN is possible. It allows to compare images and spot the differences (e.g. schemes of architects to show the progress).
- The OpenGL/FreeType2 Text Rendering Library (OGLFT) supplies an interface between a font and an OpenGL or Mesa application.It uses the FreeType library to read font faces from their files and renders text strings as OpenGL primitives. Characters can be rendered in a variety of ways, including as raster images, as tessellated polygons and as texture maps. Glyphs can be drawn individually or as a string, and can be rendered using UNICODE characters via the QString class (with Qt support). You can also combine several fonts together in one OGLFT Face to increase the coverage of UNICODE points or for other special effects. Strings can be rotated through any angle, and drawn right, centered or left justified. Additionally each character in a string can be rotated through a given angle.
- PikoPixel is a free, open-source application for drawing & editing pixel-art images & icons.
- Easy to use
- Unlimited undo
- Supports multiple layers
- Customizable canvas background & grid patterns
- Hotkey-activated popup panels
- Export upscaled images
- Supports linear (gamma-correct) color blending
