[vtkusers] 2Djpg -> 3Dgipl

[Petra Schneider]

Dear All,

I would like to use VTK CISG-RegistrationToolkit to register a set of 2D 
images, originally in .jpg. Out of this reason, I have to convert my files to 
gipl-format, but failed until now.

I tried to use the simple IO example provided by ITK (see Code below, I tried 
different PixelValues). The results look good, but vtkview always crashes, if 
I try to load the new generated files.
 
vtkconvert didn't read the jpg-files.I don't know, if it doesn't accept jpg in 
principle (perhaps, the reason just lies in the wrong dimensionality...)

Has anybody done this before?
How can I convert the jpg files to gipl format (or any other format compatible 
with VTK CISG)? 


Thanks in advance,

        Petra
