NoteLab

NoteLab brings the power of digital note taking to Linux, Windows, Mac OS X, and Solaris. Using NoteLab is just like writing with a pen on real paper. However with NoteLab, the pen and paper are electronic, you never run out of ink, and you have all the paper you'll ever need. NoteLab is free software licensed under the GNU GPL. Like Linux and Firefox, NoteLab and its full source code are available at no cost for anyone to view, analyze, scrutinze, and improve.

NoteLab saves your notes in the industry standard SVG (Scalable Vector Graphic) format. Thus any program that can understand this open, next-generation graphic format can be used to view NoteLab files. NoteLab can also print your notes or export them to a number of image types including PNG and JPEG. NoteLab allows the user to select en tire words, stretch them, move them, change their color, change their line width, delete them, and bring them back. Simply speaking, NoteLab understands a stroke as a complex shape. It doesn't just look at the page as a collection of ink on a page, but instead as a collection of words in a dynamic environment.

GardenSketch

GardenSketch is design software which can help plan and lay out any area, from the smallest garden plot to the largest landscape, enabling the planner to visualize a garden space before any plants are purchased, in color, in any season.GardenSketch's specialized drawing tools make designing landscapes easy. The existing landscape can be easily entered by incorporating aerial or satellite photos.

GardenSketch enables the planner to choose suitable plants with its advanced search capability. It makes buying plants and mulch easy by computing the number of plants and/or amount of mulch required for an area.For home users, GardenSketch saves information about last year's planting season, (ex: germination, plant-out dates, and degree of success) and can help determine the optimum time to plant seedlings. It can even print labels for flats/pots when starting seeds.For commercial users, GardenSketch is compatible with an open XML file format, and uses OpenGL to maintain speed even with large numbers of plantings. GardenSketch can handle large plans by managing smaller garden plots overlayed on a master plan. GardenSketch can be customized after purchase by using plug-ins.

Using it, you can

• Design layouts in any scale and gauge,
• Use the predefined libraries for many popular brands of turnouts to help you get started easily,
• Add your own favorite components,
• Manipulate track much like you would with actual flex-track to modify, extend and join tracks and turnouts,
• Test your design by running trains, including picking them up and moving them with the mouse.
• At any point you can print the design in a scale of your choice. When printed in 1:1 scale the printout can be used as a template for laying the track to build your dream layout.
• Learning XTrackCAD is made easy with the extensive on-line help and demonstrations.

XTrackCAD is available for free on Windows, LINUX and MacOSX.

jPicEdt

jPicEdt is a vector-based graphic editor for LaTeX and related packages. The LaTeX picture environment is a special environment for inserting simple drawing commands into a LaTeX file. This environment was obviously not intented to replace more sophisticated graphical formats such as Postscript or PDF (and their associated design tools: Adobe Illustrator, Macromedia Freehand,...), but was merely aimed at easily incorporating small and simple drawings (e.g. graphs, electrical schematics,...)

Yet picture commands are flexible enough to allow one to build rather complicated drawings, including circles, rectangles, lines and vectors, bezier splines.

Besides, using epic/eepic or PsTricks packages largely increases the set of available commands, and amongst other things, allows for shape-filling (and colours with PsTricks) and a better rendering of shapes.

Finally, one of the main benefits of using the picture environment is the ability to incorporate text containing any LaTeX command allowed in LR mode, e.g. equations, arrays or user-defined commands.

Sailcut CAD

Sailcut CAD is a sail design and plotting software which allows you to design and visualise your own sail and compute the accurate development of all panels in flat sheets. The original Sailcut was a Basic program developped by Robert Lainé in 1978. The new version, called Sailcut CAD, is written in C++ and is developped jointly by Robert Lainé and Jeremy Lainé. It is distributed under the terms of the GNU Public License (GPL).

Sailcut CAD is able to do cross cut, twist foot cut, vertical cut, mitre cut and radial cut sail design as well as wing sails, all in a number of languages. It also includes a viewer where you can assembled a hull, a rig and a set of sails to see how they match. Sailcut CAD has been successfully used for making sails for racing and cruising yacht as well as for model boats.

Skencil

Skencil is a Free Software interactive vector drawing appliction. Known to run on GNU/Linux and other UNIX-compatible systems, it is a flexible and powerful tool for illustrations, diagrams and other purposes.

A somewhat unique (for a drawing program) feature of Skencil is that it is implemented almost completely in a very high-level, interpreted language, Python. Python is powerful, object-oriented and yet easy to use.

Just a few highlights about Skencil's features

• Bézier Curves
• Transformed text and images
• Bézier curves, rectangles and ellipses can be used as guides
• Gradient fills
• Blend groups
• Writes EPS files
• Text along a path
• many more...

DrawSWF

DrawSWF is a simple drawing program written in Java2. You can save your drawings as animated flash file.

The internal storage format is SVG which means that DrawSWF can also be (ab)used as DrawSVG (no animations yet). By changing the internal storage format to SVG it is no longer possible to load animations created before DrawSWF 1.2.0

At the moment the following graphic operations are implemented:

• freehand drawing (line)
• ellipses
• rectangles
• straight lines
• text (with already 2 effects)
• picture import

other features:

• editing of objects
• fillcolor (incl. alphachannel)
• strokecolor (incl. alphachannel)
• strokewidth
• siteproportion
• backgroundimage as template
• storage format SVG

Synfig Animation Studio

Synfig is a powerful, industrial-strength vector-based 2D animation software package, designed from the ground-up for producing feature-film quality animation with fewer people and resources. While there are many other programs currently on the market to aid with the efficient production of 2D animation, we are currently unaware of any other software that can do what our software can.

Synfig eliminates the task of manual tweening, producing smooth, fluid motion without the animator having to draw out each frame individually. This allows you to produce 2D animation with fewer people while producing art of a higher quality.
