FeatherAlphaBlendCommand Constructor(RasterImage,LeadPoint,LeadRect,RasterImage,LeadPoint)

Summary

Initializes a new FeatherAlphaBlendCommand class object with explicit parameters.

Syntax

Objective-C

C++/CLI

Java

Python

public FeatherAlphaBlendCommand( 
   RasterImage sourceImage, 
   LeadPoint sourcePoint, 
   LeadRect destinationRectangle, 
   RasterImage maskImage, 
   LeadPoint maskSourcePoint 
)

- (instancetype)initWithSourceImage:(LTRasterImage *)sourceImage sourcePoint:(LeadPoint)sourcePoint destinationRectangle:(LeadRect)destinationRectangle maskImage:(LTRasterImage *)maskImage maskSourcePoint:(LeadPoint)maskSourcePoint NS_DESIGNATED_INITIALIZER;

public FeatherAlphaBlendCommand( 
   RasterImage sourceImage, 
   LeadPoint sourcePoint, 
   LeadRect destinationRectangle, 
   RasterImage maskImage, 
   LeadPoint maskSourcePoint 
);

public: 
FeatherAlphaBlendCommand(  
   RasterImage^ sourceImage, 
   LeadPoint sourcePoint, 
   LeadRect destinationRectangle, 
   RasterImage^ maskImage, 
   LeadPoint maskSourcePoint 
)

__init__(self,sourceImage,sourcePoint,destinationRectangle,maskImage,maskSourcePoint) # Overloaded constructor

Parameters

sourceImage
RasterImage object that references the source image.

sourcePoint
LeadPoint structure that contains the origin of the source rectangle. The width and height are the same width and height for the destination rectangle.

destinationRectangle
LeadRect structure that contains the destination rectangle.

maskImage
RasterImage object that references the fade mask. If you want to combine the two images just with opacity set this property to null.

maskSourcePoint
LeadPoint structure that contains the origin of the mask rectangle. The width and height for the mask rectangle are the same width and height for the destination rectangle.

Example

Run the FeatherAlphaBlendCommand on an image.

Java

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Effects; 
 
 
public void FeatherAlphaBlendConstructorExample_S2() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "Master.jpg")); 
 
   // Prepare the command 
   try 
   { 
      RasterImage maskImage; 
      // Loading the maskimage. 
      maskImage = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, @"ImageProcessingDemo\Image3.cmp"), 24, CodecsLoadByteOrder.Bgr, 1, 1); 
      FeatherAlphaBlendCommand command = new FeatherAlphaBlendCommand(image, new LeadPoint(image.Width / 2, image.Height / 2), new LeadRect(0, 0, image.Width / 2, image.Height / 2), maskImage, new LeadPoint(image.Width / 2, image.Height / 2)); 
      command.Run(image); 
      codecs.Save(image, Path.Combine(LEAD_VARS.ImagesDir, "Result.jpg"), RasterImageFormat.Jpeg, 24); 
   } 
   catch (Exception exception) 
   { 
      MessageBox.Show(exception.Message); 
   } 
 
} 
 
static class LEAD_VARS
