Used to change the default minimum value expected within the image.

A Double value.  

object.RangeMin [= value]

The RangeMin Property syntax has these parts:

Used by client code to contain clipping values used for image access. Note that 8 bit pixels are always in the range 0 to 255.

Note that the properties are not verified in context with each other, also there is no interaction -- setting the McImageType object to Monochrome does not set NumberOfChannels to one; the client must explicitly do it.

Note also that setting the RangeMax value also sets the MaxCastingLuminance value, so be sure to set RangeMax prior to setting MaxCastingLuminance.

E_POINTER implies the argument pointer is invalid.
