TextureAlphaBlendCommand Constructor(RasterImage,LeadPoint,LeadRect,Int32,RasterImage,RasterImage,LeadPoint)
See Also  Example
Leadtools.ImageProcessing.Effects Namespace > TextureAlphaBlendCommand Class > TextureAlphaBlendCommand Constructor : TextureAlphaBlendCommand Constructor(RasterImage,LeadPoint,LeadRect,Int32,RasterImage,RasterImage,LeadPoint)



sourceImage
RasterImage object that references the source image.
sourcePoint
LeadPoint structure that contains the origin of the source rectangle.
destinationRectangle
LeadRect structure that contains the destination rectangle.
opacity
Opacity value used when combining the areas from the result of feathering and destination images. Valid values range from 0 to 255.
maskImage
RasterImage object that references the fade mask, if you want to combine the two images just with opacity set this parameter to null.
underlayImage
RasterImage that references the image to be used as the underlying image. The command will use this image to underlay the mask image. You could ignore this parameter effect by passing null.
underlayOffset
References the underlay image offset with respect to the destination image. The command will use this point to calculate the parts of the underlay image that will be applied to the mask image. Using this point gives the user the ability to provide the feel of continuous texture when applying this command to neighboring parts inside the destination image using the same or different mask. If underlayImage is null also set this parameter to null.
Initializes a new Leadtools.ImageProcessing.Effects.TextureAlphaBlendCommand class object with explicit parameters.

Parameters

sourceImage
RasterImage object that references the source image.
sourcePoint
LeadPoint structure that contains the origin of the source rectangle.
destinationRectangle
LeadRect structure that contains the destination rectangle.
opacity
Opacity value used when combining the areas from the result of feathering and destination images. Valid values range from 0 to 255.
maskImage
RasterImage object that references the fade mask, if you want to combine the two images just with opacity set this parameter to null.
underlayImage
RasterImage that references the image to be used as the underlying image. The command will use this image to underlay the mask image. You could ignore this parameter effect by passing null.
underlayOffset
References the underlay image offset with respect to the destination image. The command will use this point to calculate the parts of the underlay image that will be applied to the mask image. Using this point gives the user the ability to provide the feel of continuous texture when applying this command to neighboring parts inside the destination image using the same or different mask. If underlayImage is null also set this parameter to null.

Example

Run the Leadtools.ImageProcessing.Effects.TextureAlphaBlendCommand on an image.
