How to implement a vtkImageData with boolean data?

Hello,
Is it possible to create a vtkImageData with boolean data? For example:

myImage = vtkSmartPointer<vtkImageData>::New();
myImage->AllocateScalars(VTK_FLOAT, 1);  // is boolean possible?

Thank you,
Michelle

Boolean values are stored in VTK arrays as unsigned char, so use VTK_UNSIGNED_CHAR type when you allocate scalars.

Perfect. Thank you!
