GIMP Python plugin that uses GEGL via pygegl

---
- ! 'I want to write a GIMP Python plugin that uses GEGL via pygegl (a Python extension that wraps GEGL.)

It seems that neither the GIMP PDB nor PyGIMP has a method to get a TileManager. You need a pointer to a TileManager as a parameter to gegl_node_new_child() when creating an input node connecting GEGL to a GIMP drawable.

I plan to modify PyGIMP to add drawable.getTileManager(), which would call gimp_drawable_get_tiles() and return the value as a Python long. Then you could pass that as a parameter to pygegl.new_child().

Is there an easier way, or flaws in the design?

(and raise an error if pygegl is\nnot installed) -\n\nregards,\n\n \ js\n -> _______________________________________________\n> gimp-developer-list mailing list\n> gimp-developer-list@gnome.org\n> http://mail.gnome.org/mailman/listinfo/gimp-developer-list\n>"
