1. A method for converting graphic object data that defines a graphic object for delivery to wireless devices connected to a wireless communications network, the method comprising:

  • converting, by a graphic format conversion system on a computer, the graphic object data from a path format to a second format, the path format including path elements that are each associated with a fill style and define one or more polygon shapes, each polygon shape at least partially filled with the associated fill style, the path elements collectively defining the graphic object,the converting including;

    redefining the polygon shapes defined by the path elements as groups of triangles; and

    combining at least some triangles in the groups of triangles into further polygon shapes that fall within complexity thresholds based on predetermined capabilities of a wireless device to which the converted graphic object data will be delivered.
