Description

Implementing support for this new VOI LUT Function would be straightforward (i.e. similar to SIGMOID), if there wouldn't be an issue with small values for Window Width (even < 1.0 is allowed). Therefore, the transformation pipeline in the DicomImage class library has to be extended by also supporting floating point values (32- or 64-bit) for the intermediate pixel data representation.

If I remember correctly, some forum user (?) already extended the various data type switch-statements by floating point values.

This new feature might also be interesting for RT Dose objects and some CR images ...
