Hello, I would like to develop a very specific functionality which checks attributes of a vector graphic file, available in SVG and/or EPS formats. For that, I would like to develop a small tool which has the following basic functions: + loads and displays a vector graphic from EPS/SVG + zoom/pan functionality + shows attributes of the graphic (e.g. number of nodes) + creates an offset area (with some specific logical attributes) Main criteria: people should be able to use my software for free. What would be the right approach, the right software for that? Any extensible free vector graphics editor? Or a good vector graphics developer framework? (.NET/C++) - - - - - - Results of my own research: Since the tool should be free, developing an Adobe Illustrator plug-in is not a good idea. (Although, this environment has a great support and documentation.) InkScape plug-in would be an alternative. However, there is virtually no documentation. People suggest to reverse engineer available plug-ins and learn from these.
