[Insight-users] Re: Importing image data from a byte array

[Brian Eastwood]

Hi Chris,

You are looking for the itk::ImportImageFilter.  An example of how to 
use it is in the Getting Started V guide available here:

http://www.itk.org/HTML/Tutorials.htm

You first need to set up the size, origin, and spacing of your image.  
The method ImportImageFilter::SetImportPointer() allows you to pass the 
pointer to your image buffer--you specify the size of the image buffer 
and indicate whether you want ITK to manage the buffer memory.

Hope this helps.
Brian
