Parameters

contrast: Halftone pattern contrast. Increasing this value increases the pattern brightness, making it more visible.
ripple: Halftone pattern frequency. Internally, this value is divided by 100. For example, if ripple = 200 the actual frequency is 2. Increasing this value increases the number of dots, lines, etc. in the pattern.
angleContrast: Angular pattern contrast. Increasing this value increases brightness of the "spokes" in the image.
angleRipple: Angular pattern frequency. This value determines how many "spokes" appear in the image.
angleOffset: Angular pattern offset in hundredths of degrees (+/-). A positive value will rotate the screen clockwise, while a negative value will rotate the screen counter-clockwise.
foreGroundColor: Value that specifies the foreground color for any exposed areas.
backGroundColor: Value that specifies the background color for any exposed areas.
type: Value that indicates which halftone pattern type to use.
