<div dir="ltr"><div>Hi Pedro,<br><br></div>The vtkPNGWriter supports either 8-bit or 16-bit integral components with 1, 2, 3, or 4 channels (gray, gray+alpha, rgb, and rgb+alpha). If your vtkImageData uses unsigned short as it's scalar type then the full range should get saved, so it won't be 10-bit but it will be 16-bit and you'll still get all your pixels data correct. That being said, both the PNG spec and libpng only allow for bitdepths of 1, 2, 4, 8, and 16, so a 16-bit PNG is the best you'll probably get. I wouldn't worry about the "wasted space" from the extra bits as compression should drop that to effectively nothing. The consuming application would just need to be aware of the reduced sample range, i.e. [0:1023] instead of [0:65535].<br><br><div class="gmail_extra"><br clear="all"><div><div class="gmail_signature"><div dir="ltr">- Chuck<br></div></div></div>
