Result
Returns the value.
Description
Queries which value in an image should be interpreted as the darkest shadow.All values darker than this value will be clipped to this value.
Whether darker values are smaller or larger can be determined by examining the Current value of PixelFlavor.
Source
If more or less than 8 bits are used to describe the image, the actual data values should be normalized to fit within the 0-255 range. The normalization need not result in a homogeneous distribution if the original distribution was not homogeneous.
Plugin uses value -10000 for undefined/default.
