I'm assuming that these SVGs are rendered at initialization time into bitmaps using Cairo.
But either way, I think there is a big performance problem with Cairo on the XO. I see it again and again in my activities, so far in Bounce, Typing Turtle and even Yay! Bee See; drawing simple shapes and images with Cairo seems to always kill interactivity. In Bounce I had to switch to custom gdk.Image based code in a C extension. I would have done PyGame except it doesn't allow for GTK widgets. I would like to see someone try getting in touch with Carl Worth ( www.cworth.org) and ask him to look at Cairo performance on an XO. I've tried contacting him in the past but not gotten a response. It might be that we need to switch to an integer-only version, enable some optimization flags, or something similarly simple. -Wade On Sun, Dec 7, 2008 at 5:17 PM, Erik Blankinship <[EMAIL PROTECTED]>wrote: > Are you rendering SVGs to bitmaps once, and then using the bitmaps from > thereon? > > (This does not solve the svg performance problem, but attempts to limit its > effect). > > On Sat, Dec 6, 2008 at 12:54 PM, Walter Bender <[EMAIL PROTECTED]>wrote: > >> I have been trying to speed up Turtle Art, which initializes much >> slower (4x) since I converted from GIF to SVG.
