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.
