This looks like a bug to me. I can't see itkTIFFImageIO closing the file. Also,
the write should not silently fail. <br>

I have already tested writing to a different name and it works just fine. <br>
Only when input name == output name do I get a problem: the original file is<br>
not modified.<br>
<br>
The part of the code that fails is in Itktiffimageio.cxx, in the<br>
TIFFImageIO::InternalWrite function.<br>
The problem appears at the following piece of code: <br>
<br>
TIFF *tif = TIFFOpen(m_FileName.c_str(), "w");<br>
if ( !tif )<br>
{<br>
itkDebugMacro( << "Returning" );<br>
return;<br>
}<br>
<br>
In my case !tif == true because the image was already open at the beginning <br>
of the pipeline.<br>
<br>
Surprisingly it works with BMP images though. Does this mean TIFF files<br>
cannot be modified in-place?<br>

Hi Sébastien,<br>
I think I have done this, sometimes without even realising :(<br>
Try writing with a different name to see if that is the problem.<br>
Good luck, <br>
