Detailed Description

Import data from a C array.

vtkImageImport provides methods needed to import image data from a source independent of VTK, such as a simple C array or a third-party pipeline. Note that the VTK convention is for the image voxel index (0,0,0) to be the lower-left corner of the image, while most 2D image formats use the upper-left corner. You can use vtkImageFlip to correct the orientation after the image has been loaded into VTK. Note that is also possible to import the raw data from a Python string instead of from a C array. The array applies on scalar point data only, not on cell data.
