Thanks for the response. Bug reported.<br>David<br><br><br><div class="gmail_quote">On Feb 4, 2008 2:56 PM, Bill Lorensen <<a href="mailto:bill.lorensen@gmail.com">bill.lorensen@gmail.com</a>> wrote:<br><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
<div>David,</div>
<div> </div>
<div>This certainly looks like a bug. I just checked the code for itkAnalyzeImageIO.cxx. In ReadImageInformation there is a switch statement on the data type and the code does nothing for RGB data. I'm not sure why it wrote an image, it should throw an exception.</div>
<div> </div>
<div>Can you submit a bug report? <a href="http://www.itk.org/Wiki/ITK_Procedure_for_Contributing_Bug_Fixes" target="_blank">http://www.itk.org/Wiki/ITK_Procedure_for_Contributing_Bug_Fixes</a></div>
<div>Also, if you have a small RGB image pleased attach it to the bug report.</div>
<div> </div>
<div>Thanks,</div>

My image is an RGB image with an unsigned short pixel type.<br>ITK documentation tells me that an Analyze image file : <br>
<blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">containing usually uncompressed voxel data for the images in one of the several possible voxel formats:
<ul>
<li>24 bit RGB, 8 bits per channel</li></ul></blockquote>Ok, so I imagine that my RGB-16bits-pixel will not be accepted for the Analyze format.<br>Question is, why does it write the RGB-16bits-pixel without problem or warning, but cannot read it ?<br>
I think it would be more logical to be able to read/write or nothing.<br>Or perhaps I'missing something...<br><br>For info, I've no problem with the same data using a raw image file (mdh+raw).<br>I could forward some code if necessary...<br>
