Dot Types

The gxDotTypes enumeration defines the possible halftone dot types:

enum gxDotTypes{
   gxRoundDot = 1,
   gxSpiralDot,
   gxSquareDot,
   gxLineDot,
   gxEllipticDot,
   gxTriangleDot,
   gxDispersedDot
};

typedef long gxDotType;

The meaning of each dot type is evident from its name, except perhaps for gxDispersedDot. The gxDispersedDot dot type uses a seemingly random pattern
of small dots that gradually fill up each cell as the tint value increases. For a visual representation of each of these dot types, see Figure 7-6 on page 7-16.
