[Dcmlib] vtkgdcmViewer

[jean-michel.rouet at philips.com]

Bonjour,

Lorsque je fais tourner vtkgdcmViewer sur l'image 
ACUSON-24-YBR_FULL_422-Jpeg_Baseline_1.dcm
le viewer affiche correctement la premiere image, mais des que j'appuie 
sur une touche, alors la le programme se fige. plus rien ne marche.

Qu'a cela ne tienne, j'ai lancé purify dessus pour voir ce qui se passe, 
et j'ai compilé vtk (version cvs) en debug.
resultat des courses, un debordement de tableau apparait dans 
vtkImageMapToWindowLevelColorsExectue()

mais j'y comprend pas grand chose de plus... (ci joint la sortie de 
purify).
Est-ce un probleme du a vtk, ou est-ce un probleme du au vtkgdcmViewer qui 
utilise mal vtk ??? 

JM
