public: 
ColorHalftoneCommand(  
   int maximumRadius, 
   int cyanAngle, 
   int magentaAngle, 
   int yellowAngle, 
   int blackAngle 
) 

Parameters

maximumRadius
Maximum dot(i.e. circle) size, in pixels. This value should not be less than 5.

cyanAngle
Cyan screen angle in a hundredths of degrees (+/-). A positive value will rotate the screen clockwise, while a negative value will rotate the screen counter-clockwise. Valid values are from -36000 to + 36000.

magentaAngle
Magenta screen angle, in a hundredths of degrees (+/-). A positive value will rotate the screen clockwise, while a negative value will rotate the screen counter-clockwise. Valid values are from -36000 to + 36000.

yellowAngle
Yellow screen angle in a hundredths of degrees (+/-). A positive value will rotate the screen clockwise, while a negative value will rotate the screen counter-clockwise. Valid values are from -36000 to + 36000.

blackAngle
Black screen angle in a hundredths of degrees (+/-). A positive value will rotate the screen clockwise, while a negative value will rotate the screen counter-clockwise. Valid values are from -36000 to + 36000.
