Hi, I had the need to render SVG in memory. I placed a drawToString()-Function in renderSVG: def drawToString(d, showBoundary=rl_config.showBoundary): "Returns a SVG as a string in memory, without touching the disk" s = getStringIO() drawToFile(d, s, showBoundary=showBoundary) return s.getvalue() Regards, Dirk
