windows - What exactly is the text height GetTextExtentPoint returns? -

on windows, gettextextentpoints , friends homecoming size construction contains height , width of given string. wonder height exactly, e.g. font height or without external leading or actual height of string. latter mean height value depends on actual string. e.g. "mmm" have height "aq".

i tried it: gettextextentpoints returns font size including internal leading excluing external leading, i.e. cell size. value not depend on actual string. (it text width obviously.)
