</pre><br>It uses vtkVolume16Reader to read the 16 bit files. I would like to know the 8 bit counterpart of this class. If not, any other class that can read multiple 8 bit files in a similar manner.<br><br>regards,<br>D Rathore<br>

Hi,<br><br>I used to write short VTK python scripts for processing high number of files. In your case, it could be a simple loop on our files that, for each, do<br>- Read<br>- Cast to unsigned char (vtkImageCast -> be careful of type conversion. vtkImageShiftScale could be another solution)<br>

It takes 16 bit files in the format xxx.1, xxx.2, xxx.3 etc. All works to taste.<br>
<br>The Problem - How can I supply it 8 bit files? I have around 800 files and converting them to 16 bit will double the data size - too huge for my graphics card.<br>
