Hi Sankhesh,

Thanks for the reply.

By quality I mean that the first image looks crispy, while the second one looks very smooth.
But now that you said, I will see if I can find any data type inconsistency accross my code.

ManageWindowLevel is enabled on vtkResliceCursorWidget.


Thanks again,

Enzo

This could either be due to the data type differences in the output image or actual data value differences. Do you have ManageWindowLevel enabled for vtkResliceCursorWidget?
