VRR

VRR is a vector image editor that has been exclusively designed for creating illustrations of mathematical articles. However, it is not limited to this capability only. The software's many types of geometric objects and their dependencies make for an efficient editing experience. Its cooperation with TeX and scripting in Scheme makes for a seamless workflow. Real-size dimensions make for accurate measurements while the software's support for a wide range of file formats, including PS, EPS, PDF, and SVG, provides flexibility in file exports.

To use VRR, the software requirements include several development tools such as GNU make, gcc 3.0 or higher, gawk, perl, GTK+ version 2.6.0 or higher, guile-1.6, kpathsea, fontconfig 2.3.1 or higher, pdfTeX, zlib, and libxml2.
