MemoryEfficientSetFrame(RasterImage,int,DateTime,bool) Method

Fills the 3D object with data from the specified Leadtools.RasterImage sent through the
public void MemoryEfficientSetFrame( 
   RasterImage image, 
   int frameIndex, 
   DateTime captureTime, 
   bool remove 
void MemoryEfficientSetFrame(  
   RasterImage^ image, 
   int frameIndex, 
   DateTime captureTime, 
   bool remove 


Leadtools.RasterImage used to fill a portion of the object.

The index that represents the place of the image to set in the 3D object.

Creation time of the set frame. Get this value from the DICOM file.

true to dispose of the image after copying its data and placing it in the 3D object; false, otherwise.

  • Add the Medical3DObject to the Medical3DContainer before using this method. Refer to the Medical3DContainer.Objects collection.
  • Initialize the efficient memory feature before using this method. To do so, use the MemoryEfficientInit method.
  • You need to call this method multiple times, each with a different frameIndex, in order to fill the 3D object. The number of times is based on the depth depth
    The depth of the 3D object, or the number of frames used to create the 3D object.

    parameter used when calling MemoryEfficientInit.

  • You do not need to set frames in order. However, you need to fill the whole object by covering all the indexes from 0 to depth - 1. The area that was not filled will be black when rendering the object.

  • this overloaded method is used when you want to sort the series frames based on their InstanceCreationTime DICOM tag.
