And Atril uses the values from the hhea table (found by hexediting).
#define TO_TTF(x) qRound(x * 2048. / ppem)
This is used in things like…
font.hhea.maxAdvanceWidth = TO_TTF(fontEngine->maxCharWidth());
… but not in…
font.hhea.ascender = qRound(properties.ascent);
font.hhea.descender = -qRound(properties.descent);
font.hhea.lineGap = qRound(properties.leading);
… and of course not when the OS/2 table is copied:
if (!noEmbed) {
QTtfTable os2;
os2.tag = MAKE_TAG('O', 'S', '/', '2');
os2.data = fontEngine->getSfntTable(os2.tag);
if (!os2.data.isEmpty())
tables.append(os2);
}
(all examples from stretch’s Qt, as the oldest I had at hand)
