- (instancetype)initWithMaximumRadius:(NSUInteger)maximumRadius cyanAngle:(NSInteger)cyanAngle magentaAngle:(NSInteger)magentaAngle yellowAngle:(NSInteger)yellowAngle blackAngle:(NSInteger)blackAngle NS_DESIGNATED_INITIALIZER; 
public ColorHalftoneCommand( 
   int maximumRadius, 
   int cyanAngle, 
   int magentaAngle, 
   int yellowAngle, 
   int blackAngle 
); 
public: 
ColorHalftoneCommand(  
   int maximumRadius, 
   int cyanAngle, 
   int magentaAngle, 
   int yellowAngle, 
   int blackAngle 
) 
__init__(self,maximumRadius,cyanAngle,magentaAngle,yellowAngle,blackAngle) # Overloaded constructor 

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.

Example

Run the ColorHalftoneCommand on an image.

C#
Java
using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Effects; 
 
 
public void ColorHalftoneConstructorExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, @"ImageProcessingDemo\Beauty16.jpg"), 16, CodecsLoadByteOrder.BgrOrGray, 1, 1); 
 
   // Prepare the command 
   ColorHalftoneCommand command = new ColorHalftoneCommand(15, 10800, 16200, 9000, 4500); 
   command.Run(image); 
   codecs.Save(image, Path.Combine(LEAD_VARS.ImagesDir, "Result.jpg"), RasterImageFormat.Jpeg, 24); 
 
}
