public class BricksTextureCommand : Leadtools.ImageProcessing.RasterCommand, Leadtools.ImageProcessing.IRasterCommand

'Declaration
 
Public Class BricksTextureCommand 
   Inherits Leadtools.ImageProcessing.RasterCommand
   Implements Leadtools.ImageProcessing.IRasterCommand

'Usage
 
Dim instance As BricksTextureCommand

public sealed class BricksTextureCommand : Leadtools.ImageProcessing.IRasterCommand

function Leadtools.ImageProcessing.SpecialEffects.BricksTextureCommand()

public ref class BricksTextureCommand : public Leadtools.ImageProcessing.RasterCommand, Leadtools.ImageProcessing.IRasterCommand

This command creates a brick-like texture. Edges that are in the angle of the light source are brightened and the others are darkened. Apply this texture to an image by using image as the source image. You can obtain the best result by applying this command on a medium brightness image.
Using the shading option of BricksTextureCommandFlags.SmoothedOutEdges results in bricks that have a more chiseled look than the same settings with a shading option of BricksTextureCommandFlags.SmoothedInEdges.
As an example, suppose you were to start with a gray image, like the following figure:

Now suppose you call the BricksTextureCommand command. The following settings apply to all of the following figures:

Parameter	Value
OffsetX	0
OffsetY	0
RowDifference	35
BricksWidth	60
BricksHeight	20

If you were to use the following additional settings:

Parameter	Value
MortarRoughness	0
MortarRoughnessEvenness	0
BricksRoughness	0
BricksRoughnessEvenness	0
Flags	BricksTextureCommandFlags.SmoothedOutEdges

The following figure results:

Note how smooth the surface of both the mortar and the bricks is. In the following figure, the only change from the previous settings is the value of BricksRoughness, which is set to 196:
In the following figure, BricksRoughness remains set to 196 and in addition, BricksRoughnessEvenness is set to 4:

The next two figures show the difference between the BricksTextureCommandFlags.SmoothedOutEdges flag and the BricksTextureCommandFlags.SmoothedInEdges flag. For these figures the following settings are used:

Parameter	Value
MortarRoughness	0
MortarRoughnessEvenness	0
BricksRoughness	250
BricksRoughnessEvenness	0
EdgeWidth	7
MortarWidth	4

In the following figure the BricksTextureCommandFlags.SmoothedOutEdges flag is set:
In the following figure the BricksTextureCommandFlags.SmoothedInEdges flag is set:
This command 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 command does not support signed data images.
This command does not support 32-bit grayscale images.
