I trust this is an appropriate place; this is my first time on this listserv. I want to add the ability to export an animation in SVG format so that I have a vectorized animation. From what I've been able to discern, this hasn't been done yet. I may have many questions related to this, so if someone is familiar with this section of the code and would be able to answer additional questions in the future, please let me know. My first hurdle is how to extract each frame of the animation. I believe I need to make a new class and inherit MovieWriter. However, MovieWriter is setup to write an image to a file for each frame, then stitch those images together (through a pipe to an external tool). But in order to add animation to the SVG, it will be much easier for me to have an XML tree as an object for each frame, rather than an XML file, so that I do not need to re-parse the XML. Here is where I am at: * I've modified backend_svg.py: - an XMLBuilder class now builds the tree from the renderer (previously, the XML data was written directly through XMLWriter) - currently, I have the svg backend (mostly) backward compatible so that I can write images to file in the normal way. I have not run the example tests yet, but need to eventually. - I added a draw method to FigureCanvasSVG which returns the XML tree * I've modified animation.py: - added SVGWriter class which inherits MovieWriter - SVGWriter modifies setup method so that an external process is not started - SVGWriter.grab_frame method grabs the XML tree (rather than printing to a file) via FigureCanvasSVG.draw - SVGWriter.cleanup goes through the XML trees and adds 'set' XML elements to create the animation * basically I copy the main group of each frame to a new XML tree and make it's "opacity" CSS attribute 1 for the duration of that frame. It is a hack to get the rest working...I'd like to actually go into the tree and only change the data that changes in each frame. I am at the point where I can get an SVG animation out of the moviewriter example at: http://matplotlib.org/examples/animation/moviewriter.html However, FigureCanvas.draw does not seem the appropriate place for this. Case in point, the background is the default gray rather than white (which you get if you savefig). Any thoughts on the best way to do this? -Tim -- View this message in context: http://matplotlib.1069221.n5.nabble.com/animation-in-SVG-tp45021.html Sent from the matplotlib - devel mailing list archive at Nabble.com.
