The GLIPS Graffiti editor is a cross-platform SVG graphics editor based on Batik and developed by ITRIS. It features shape tools (rectangles, circles, ellipses, lines, polygons, and polylines), path tools (Bezier curves, conversion to a path, union, subtraction, and intersection), basic text support, and image import (SVG or Bitmap). Supported transformations are translate, resize, rotate, and skew. A property manager is available for each object, and a resource manager takes care of gradients, patterns, markers, and filters. It requires Java VM 1.4.1 or higher. It is a part of the GLIPS Project, which aims to be a PLC cross-platform development environment.
Grant is a very responsive project manager. Sofa looks very promising from my point of view and I'm waiting for next release to use all its features.
