[Insight-users] Re: Problem with ITKrawImageIOFactory

[Luis Ibanez]

Hi cspl,

We just added two examples to better
illustrate the use of the Raw Image
reader.


You can find them under:

   Insight/Examples/RawImageReadWrite

and

   Insight/Examples/RawImageReaderViewer


The first will read a Raw image file and
save it in raw format again.

The secon is intended to be a RawViever.
(it requires FLTK to be installed in order
to support the GUI).

The interface will ask for the image size,
(this has to be filled before you hit the
"Load" button, or the "Show" button)


Please let us know if you find any
problems using these two new examples.


Thanks


Luis
