I have recently updated my software from vtk6.2 to vtk7.1 and I am having<br>
issues with window/level management on CT Data.<br>
<br>
I have a small GUI to interact with window/level values. I did not change<br>
any code, but now, with vtk7.1, it happens that pixels go black when level<br>
goes to very low values and/or window goes to very high values.<br>
(Ex: bone pixels go black after a certain threshold.)<br>
<br>
Has anyone experienced this, or could point me in the right direction?<br>
<br>
Thank you very much.<br></blockquote></div></div></div>
