[vtkusers] How read stack of TIF images

[Amy Squillacote]

Hi Carl,

You should be able to use either vtkTIFFReader 
(http://www.vtk.org/doc/release/5.2/html/a01392.html) or vtkPNGReader 
(http://www.vtk.org/doc/release/5.2/html/a01039.html). You can specify 
the file names using either the SetFileNames or 
SetFilePrefix/SetFilePattern methods in vtkImageReader2 (superclass of 
both vtkTIFFReader and vtkPNGReader). vtkImageReader2 also has methods 
for specifying the spacing, origin, etc. Also, make sure to set the file 
dimensionality to 2 since you're reading slices.
