However, when I tried running the gegl-paint in the example folder, a blank window poped up. And whenever I click on the window, I got error message : (lt-gegl-paint:2195): GLib-GObject-WARNING **: IA__g_object_new_valist: object class `GeglChantpath_c' has no property named `hardness' How should I fix this problem? Also, is there any document with more detail about the core rendering algorithm of GEGL? I got the rough idea about GEGL using DAG as the core representation and DAG could improve the rendering efficiency by better operation cache and region masking. But I can't find any document with more details about how they are actually implemented. Thanks, -Tim -------------- next part -------------- An HTML attachment was scrubbed...

The hardness property has been renamed stroke-hardness. Something else has broken elsewhere in GEGL at some point as well since fixing that still doesn't seem to cause any rendering to happen. > Also, is there any document with more detail about the core rendering > algorithm of GEGL?

The source code itself, including comments in the headers of the GeglNode and GeglOperation classes are the only proper reference of how this is currently implemented. /?yvind K. -- ?The future is already here.

Both problems have been resolved now, and the example works again. /?yvind K. -- ?The future is already here.
