VRR 0.9

VRR has a simple but powerful operation set: creating, manipulating and transforming basic graphic primitives, which are points, segments, rational Bezier curves, elliptic arcs etc. All objects can be determined not only by absolute coordinates, but also by geometric dependencies on other objects l intersections, significant points, other curves etc. When an object is changed, the dependent objects are recalculated automatically. This enables you to modify the image easily without breaking the lines visually tied together. VRR has a sophisticated system for working with text. In addition to common text objects, it allows you to create text objects typeset by TeX and make them part of your image. You can create almost anything from a short math expression to several paragraphs of a text. The editor is able to import from and export to files in common data formats (export to PDF, PS, EPS and SVG, import from IPE5 and SVG). VRR is a freely available open source program, which runs on Linux and uses a graphical user interface based on the X Window System and GTK. The authors suppose that the time spent by a user exploring VRR 's interface will bring him much joy later when he is able to use all of its powerful advanced features. The editor can be also easily extended by a plugin or by a program written in its built-in scripting language, Scheme.

The GIMP 2.2.8

It has many capabilities. It can be used as a simple paint program, an expert quality photo retouching program, an online batch processing system, a mass production image renderer, an image format converter, etc. GIMP is expandable and extensible. It is designed to be augmented with plug-ins and extensions to do just about anything. The advanced scripting interface allows everything from the simplest task to the most complex image manipulation procedures to be easily scripted.
