Leadtools.ImageProcessing.SpecialEffects Namespace : MosaicTilesCommand Class



Creates a mosaic effect on an image by dividing an image into rectangular or arc-shaped cells with irregular boundaries and modifying the color of each cell. This method is available in the Raster Pro and above toolkits.

Syntax

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

Example

Run the MosaicTilesCommand on an image.

Visual Basic Copy Code
Public Sub MosaicTilesCommandExample()
   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 MosaicTilesCommand = New MosaicTilesCommand
   command.BorderColor = New RasterColor(0, 0, 0)
   command.TilesColor = New RasterColor(255, 255, 255)
   command.TileWidth = 50
   command.TileHeight = 50
   command.Opacity = 50
   command.ShadowThreshold = 50
   command.ShadowAngle = ShadowCommandAngle.East
   command.PenWidth = 7
   command.Flags = MosaicTilesCommandFlags.Cartesian Or _
                               MosaicTilesCommandFlags.ShadowGray
   command.Run(leadImage)
   codecs.Save(leadImage, LeadtoolsExamples.Common.ImagesPath.Path + "Result.jpg", RasterImageFormat.Jpeg, 24)

   RasterCodecs.Shutdown()

Remarks

  • This method makes an image look like a mosaic made from tiles. Tiles can be rectangular or arc-shaped, depending upon the coordinate system used to draw the tiles. The method's many parameters control factors like the border color, tile color, pen width, tile width and height, etc.
  • 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 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.
