The FLAGS field is a bit mask containing zero or more of the following boolean values (unspecified bits must be zero): AllCharactersExist, InkInside, HorizontalOverlap.
The FONT-ASCENT and FONT-DESCENT fields specify the font designer s logical height of the font, above and below the baseline, respectively.The sum of the two values is often used as the vertical line spacing of the font.
The FONT-ASCENT and FONT-DESCENT fields specify the font designer s logical height of the font, above and below the baseline, respectively.The sum of the two values is often used as the vertical line spacing of the font.
If this bit is set, the two ink bounding boxes (smallest rectangle enclosing the inked pixels) of some pairs of glyphs in the font may overlap when displayed side-by-side (ie the second character is imaged at the escapement point of the first) on a common baseline.
If this bit is set, the inked pixels of each glyph fall within the rectangle described by the font s ascent, descent, origin, and the glyph s escapement point.
