concept mmcfilters::AltitudeValue =

    (detail::SupportedFloatingAltitude<T> || detail::SupportedIntegralAltitude<T>)

Detailed Description

Value types accepted by generic altitude helpers.

The concept is intentionally conservative: floating-point values are accepted, and integral values must fit safely inside the signed 64-bit difference type. bool is rejected because it has no meaningful altitude interval semantics.

Public weighted-tree and attribute APIs use this concept to keep altitude arithmetic independent of the original image pixel type while preserving the monotone ordering required by max-trees and min-trees.
