public: HalfTonePatternCommand( int contrast, int ripple, int angleContrast, int angleRipple, int angleOffset, RasterColor foreGroundColor, RasterColor backGroundColor, HalfTonePatternCommandType type ) |
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.
Run the Leadtools.ImageProcessing.Core.HalfTonePatternCommand on an image.
