Hello,<div><br></div><div>I am a DICOM viewer application developer and we use itk, gdcm and vtk.</div><div><br></div><div>Until our last release we were using itk 3.16 (with integrated gdcm 1.2.x) for reading the images and vtk 5.0 for displaying them.</div>
<div>We updated the libraries recently, so we are now using itk 3.20 (linked against external gdcm 2.0) and vtk 5.6</div><div><br></div><div>We observed a different behaviour with gdcm 2.0.x when reading MONOCHROME1 images with itkGDCM interface. The same MONOCHROME1 images that were displyed correctly with itk 3.16 are now displayed like in inverse video mode. I guess there have been some changes in the regarding classes so in prior versions (itk+gdcm) some computation in the grayscale space was performed which now it is not.</div>
<div><br></div><div>I would like to know the diferences between these versions regarding image reading and what I should do if I want to display them like itk3.16+gdcm1.2.x does.</div><div><br></div><div>This behaviour could be reproduced with the sample MONOCHROME1 images contained in <a href="http://www.creatis.insa-lyon.fr/~jpr/PUBLIC/gdcm/gdcmData.tar.gz">http://www.creatis.insa-lyon.fr/~jpr/PUBLIC/gdcm/gdcmData.tar.gz</a> like D_CLUNIE_RG1_RLE.dcm or D_CLUNIE_RG3_RLE.dcm.<br clear="all">
<br></div><div>Thanks in advance!</div><div><br>-- <br>Jesús Spínola<br>
