[Insight-users] itkImageSource for block of memory

[Andreas Schuh]

Hi Koen,

the MATLAB API gives you C array of the image pixel data. You can set  
this pixel buffer directly as pixel buffer to be used by an instance  
of itk::Image. So you don't need to copy any byte of the image pixel  
data.

Have a look at itk::Image::GetPixelContainer()
and itk::ImportPixelContainer::SetImportPointer().
