All  primitives  supported  by  the  FT800  are  defined  in  the  table  above.  The  primitive

to be drawn is selected by the Begin_G command.  Once the primitive is selected, it will be

valid till the new primitive is selected by the Begin_G command.

 

Please  Note: The primitive drawing operation will not be performed until Vertex2ii or Vertex2f is executed.
