QuickTime 4 Reference

Specifying a Color for a Path

You specify a color with which to draw paths by including a kCurveARGBColorAtom atom in a vector data stream. The default color is black. This atom is described in "Vector QT Atom Container" .

As with other atoms that specify path attributes, an attribute value specified by a kCurveTransferModeAtom atom is used for subsequent paths in the vector data stream until another atom of the same type appears in the stream or the end of the stream is reached.
