Parameters

tileWidth
Value that indicates the width of the tile, in pixels. The meaning of the TileWidth property differs according to the flags that are set in the Flags property. Possible values are:

If Flags property contains: Then, TileWidth property contains: And the range of possible values for TileHeight property is:
RomanMosaicCommandFlags.Rectangular The width of each rectangular tile, in pixels. 1 to the image width / 2, if there is no region. If there is a region, then the range of values is just the region width/2.
RomanMosaicCommandFlags.Circular The radial length of each arc-shaped tile, in pixels 1 to the half of the diagonal of the image, if there is no region. If there is a region, then the range of values is just the half of the diagonal of the region rectangle.
RomanMosaicCommandFlags.Both The radial length of each arc-shaped tile, in pixels 1 to the half of the diagonal of the image, if there is no region. If there is a region, then the range of values is just the half of the diagonal of the region rectangle.

tileHeight
Value that indicates the height of the tile. The meaning of the TileHeight property differs according to the flags that are set in the Flags property. Possible values are:

If Flags property contains: Then, TileHeight property contains: And the range of possible values for TileHeight property is:
RomanMosaicCommandFlags.Rectangular The height of each rectangular tile, in pixels. 1 to the image height / 2, if there is no region. If there is a region, then the range of values is just the region height/2.
RomanMosaicCommandFlags.Circular Will be ignored. Will be ignored.
RomanMosaicCommandFlags.Both The height of each rectangular tile, in pixels. 1 to the image height / 2, if there is no region. If there is a region, then the range of values is just the region height/2.

border
Value that indicates the border width, in pixels. The valid range is from 1 to 15.

shadowAngle
Value indicates the direction of the light source that produces the shadow. This property is used if the RomanMosaicCommandFlags.ColoredShadow flag or the RomanMosaicCommandFlags.GrayShadow flag is set. Valid values are found in ShadowCommandAngle

shadowThresh
Value that determines which pixels will be affected by the shadow. Possible values range from 0 through 255. Pixel values less than the threshold value will be unaffected. This member will be used if the RomanMosaicCommandFlags.ColoredShadow flag or the RomanMosaicCommandFlags.GrayShadow flag is set.

color
Represents the value that specifies the fill color to be used in between the tiles.

flags
Enumeration contains all flags that are needed by the RomanMosaicCommand. It is indicate the values used to select the shape of the tiles and the type of shadow.

Example

Run the RomanMosaicCommand on an image.

C#
VB
using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.SpecialEffects; 
 
public void RomanMosiacConstructorExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, @"ImageProcessingDemo\Image2.jpg")); 
 
   // Prepare the command 
   RomanMosaicCommand command = new RomanMosaicCommand(15, 15, 5, ShadowCommandAngle.East, 50, new RasterColor(0, 0, 0), RomanMosaicCommandFlags.Rectangular | RomanMosaicCommandFlags.GrayShadow); 
   command.Run(image); 
   codecs.Save(image, Path.Combine(LEAD_VARS.ImagesDir, "Result.jpg"), RasterImageFormat.Jpeg, 24); 
 
} 
 
static class LEAD_VARS 
{ 
   public const string ImagesDir = @"C:\Users\Public\Documents\LEADTOOLS Images"; 
} 
Imports Leadtools

   Dim codecs As New RasterCodecs() 
   codecs.ThrowExceptionsOnInvalidImages = True 
 
   Dim leadImage As RasterImage = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "ImageProcessingDemo\\Image2.jpg")) 
 
   ' Prepare the command 
   Dim command As RomanMosaicCommand = New RomanMosaicCommand(15, 15, 5, ShadowCommandAngle.East, 50, New RasterColor(0, 0, 0), RomanMosaicCommandFlags.Rectangular Or RomanMosaicCommandFlags.GrayShadow) 
   command.Run(leadImage) 
   codecs.Save(leadImage, Path.Combine(LEAD_VARS.ImagesDir, "Result.jpg"), RasterImageFormat.Jpeg, 24) 
 
End Sub
