Leadtools.ImageProcessing.SpecialEffects Namespace : RomanMosaicCommand Class



Segments the image into rectangular or rounded rectangular tiles and fills them with a color chosen randomly from the colors of the tile's pixels. This method is available in the Raster Pro and above toolkits.

Syntax

Visual Basic (Declaration)  
Public Class RomanMosaicCommand 
   Inherits RasterCommand
   Implements IRasterCommand 
Visual Basic (Usage) Copy Code
Dim instance As RomanMosaicCommand
C#  
public class RomanMosaicCommand : RasterCommand, IRasterCommand 
C++/CLI  
public ref class RomanMosaicCommand : public RasterCommand, IRasterCommand 

Example

Run the RomanMosaicCommand on an image.

Visual Basic Copy Code
Public Sub RomanMosiacCommandExample()
   RasterCodecs.Startup()
   Dim codecs As New RasterCodecs()
   codecs.ThrowExceptionsOnInvalidImages = True

   Dim leadImage As RasterImage = codecs.Load(LeadtoolsExamples.Common.ImagesPath.Path + "Master.jpg")

   ' Prepare the command
   Dim command As RomanMosaicCommand = New RomanMosaicCommand
   command.TileWidth = 15
   command.TileHeight = 15
   command.Border = 5
   command.ShadowAngle = ShadowCommandAngle.East
   command.ShadowThresh = 50
   command.Color = New RasterColor(0, 0, 0)
   command.Flags = RomanMosaicCommandFlags.Rectangular Or RomanMosaicCommandFlags.GrayShadow
   command.Run(leadImage)
   codecs.Save(leadImage, LeadtoolsExamples.Common.ImagesPath.Path + "Result.jpg", RasterImageFormat.Jpeg, 24)

   RasterCodecs.Shutdown()
End Sub
C# Copy Code
public void RomanMosiacCommandExample() 
{ 
   // Load an image 
   RasterCodecs.Startup(); 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(LeadtoolsExamples.Common.ImagesPath.Path + "Master.jpg"); 
 
   // Prepare the command 
   RomanMosaicCommand command = new RomanMosaicCommand(); 
   command.TileWidth    = 15; 
   command.TileHeight   = 15; 
   command.Border       = 5; 
   command.ShadowAngle  = ShadowCommandAngle.East; 
   command.ShadowThresh = 50; 
   command.Color        = new RasterColor(0,0,0); 
   command.Flags        = RomanMosaicCommandFlags.Rectangular | RomanMosaicCommandFlags.GrayShadow; 
 
   command.Run(image); 
   codecs.Save(image, LeadtoolsExamples.Common.ImagesPath.Path + "Result.jpg", RasterImageFormat.Jpeg, 24); 
 
   RasterCodecs.Shutdown(); 
}

Remarks

  • Use this method to divide the image into rectangular or rounded rectangular tiles and then fill each tile with a color chosen randomly from the colors of each tile's pixels.
  • This method can process the whole image or a region of the image. If the image has a region, the effect is applied only to the region.
  • This method supports 12- and 16-bit grayscale and 48- and 64-bit color images. Support for 12- and 16-bit grayscale and 48- and 64-bit color images is available only in the Document/Medical toolkits.
  • This method does not support signed data images.
  • This command does not support 32-bit grayscale images.
