Members:

Name	Type	Description
flags	AT_DWORD	Must be an OR of the Font Flags values. All unused flags must be off.
fontBBox	AT_PDF_FIXEDRECT	Font bounding box in 1000 EM units. (An EM is a typographic unit of measurement equal to the size of a font. In a 12-point font, an EM is 12 points.)
missingWidth	AT_INT16	Width of missing character.
stemV	AT_INT16	Vertical stem width.
stemH	AT_INT16	Horizontal stem width.
capHeight	AT_INT16	Capital height.
xHeight	AT_INT16	X height.
ascent	AT_INT16	Max ascender height.
descent	AT_INT16	Max descender depth.
Leading	AT_INT16	Additional leading between lines.
maxWidth	AT_INT16	Maximum character width.
avgWidth	AT_INT16	Average character width.
italicAngle	AT_INT16	Italic angle in degrees, if any.
style	AT_PDF_FONT_STYLES	Panose and sFamily class values.
baseLineAdj	AT_INT16	Baseline adjustment, which is a vertical adjustment for font baseline difference and writing mode 1 (vertical). This should only be used for CIDFontType 2 fonts with font substitution.
