public DicomImage Blt( 
   DicomImage sourceImage,
   System.Drawing.Point baseAreaOffset,
   System.Drawing.Point bltAreaOffset,
   System.Drawing.Size outputSize,
   System.float opacity
)

Parameters

sourceImage: Image to copy pixel data from
baseAreaOffset: Offset of this(base) image
bltAreaOffset: Offset of the source image
outputSize: Size of the pixel data in destination image
opacity: Alpha value for the source image when combined with this image. Valid values are ranging from 0 - 1, by default full opacity (1) is set

Remarks

Source and base images' Frame and Zoom can be used to select the frames and zoom level when the images are combined

Example

DicomImage image = new DicomImage("your_dicom_image.dcm");
DicomImage image2 = new DicomImage("your_dicom_image2.dcm);
                    
Point baseOffset = new Point(0, 0);
Point bltOffset = new Point(512, 0);
Size finalSize = new Size(1024, 512);
                    
DicomImage blendedImage = image.Blt(image2, baseOffset, bltOffset, finalSize);
blendedImage.Export("path_to_export_location_img.png", "png", 1);
