Thanks! It's not clear if you are asking about how the SVG path command are parsed, normalized, and interpreted into a path composed of vector primitives or how those paths actually get rendered into pixels. If the former, you may be interested in the svg.path package which does exactly that (and only that). Most vector drawing libraries (Agg, the painting API of any reasonable GUI toolkit) will be able to implement those primitives to draw onto a pixel image. https://pypi.python.org/pypi/svg.path/ -- Robert Kern ___ NumPy-Discussion mailing list NumPy-Discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussion

There are several open source libraries that implement SVG rendering, you may look at those to see how the rendering can be implemented in practice. InkScape is particularly nice -- it's an open source desktop vector drawing program, but can also be called on the command line and used as a SVG renderer. Someone wrote a minimal wxPython-based SVG renderer a while back -- not sure what happened to that. -Chris -- Christopher Barker, Ph.D. Oceanographer Emergency Response Division NOAA/NOS/ORR(206) 526-6959 voice 7600 Sand Point Way NE (206) 526-6329 fax Seattle, WA 98115 (206) 526-6317 main reception chris.bar...@noaa.gov ___ NumPy-Discussion mailing list NumPy-Discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussion

Does anyone on this list know how Scalable Vector Graphics C, S, etc. command data are translated into curves (i.e., pixel maps) and might you be willing to answer some questions off-list? Thanks!
