| Summary | 0000990: vtkImageReslice LinearInterpolation Round off bug | ||||||||
| Description | Floating point image volumes with scalars in the range 0-1 are incorrectly resliced as the result is round to either 0 or 1. I'm using this functionality for color overlay display of feature images that contain scalars in that range. Switching to nearestneighbour solves the round-off problem, but produces unattractive images. Remove line 1111 (CVS-1.41) stating vtkResliceRound(result, *outPtr++); | ||||||||
