boost::gil::histogram::erase

Declared in <boost/gil/histogram.hpp>

@{

This function erases an element, pointed to by the given iterator, from an %unordered_map. Note that this function only erases the element, and that if the element is itself a pointer, the pointed‐to memory is not touched in any way. Managing the pointer is the user's responsibility.

An iterator pointing to the element immediately following __position prior to the element being erased. If no such element exists, end() is returned.
