It is easy to create an ITK image, allocate the buffer then copy your data into the buffer.  Of course this requires you to have ITK installed.<br>

Subject: [vtkusers] Setting vtkImageData from regular float array<br>
<div class="HOEnZb"><div class="h5"><br>
I have float array which represents a 2-D image. I'd like to set it into<br>
vtkImageData, but can't work out how to do this. The problem is, all the<br>
examples use a vtkReader to read in the data, I already have the data.<br>
<br>
<br>
Any help would be greatly appreciated,<br>
Thanks!<br>
<br>
<br>
