| Summary | 0014550: vtkTIFFReader reading multi-page tiff returns a volume with one more slice than was read | ||||||||
| Description | If you connect a vkvImageViewer2 viewer to a tiff reader and load a multi-page tiff, the viewer's GetSliceMin() returns 0 and GetSliceMax() returns the number of pages read, hence indicating there are one more page than actually present. This causes junk to be displayed and presumably might cause a crash. To fix, search in vtkTIFFReader.cxx for where this->DataExtent members are set. The odd numbered values should always be set to one less than the count. 5 places to fix. | ||||||||

I think that this bug was fixed for VTK 6.1, by the following commit: http://vtk.org/gitweb?p=VTK.git;a=commitdiff;h=1c4d5ee2 [^] Can you check to see whether the patch at the above URL resolves the issue for you? Or, alternatively, can you confirm that VTK 6.1 resolves the issue? |

Okay, I re-read your original report: it's not just one place, but five places in the code where the extent is set incorrectly. |

Hi Richard, please take a look at the following patch: http://review.source.kitware.com/#/c/15318/1/IO/Image/vtkTIFFReader.cxx [^] Does this fix the rest of the off-by-one errors that you saw? |
