Attributes

advance_height_max	This field is the maximum of all advance heights found in the font.
ascender	The font’s ascender, i.e., the distance from the baseline to the top-most of all glyph points found in the font.
caret_offset
caret_slope_rise	The rise coefficient of the cursor’s slope of the cursor (slope=rise/run).
caret_slope_run	The run coefficient of the cursor’s slope.
descender	The font’s descender, i.e., the distance from the baseline to the bottom-most of all glyph points found in the font.
line_gap	The font’s line gap, i.e., the distance to add to the ascender and descender to get the BTB, i.e., the baseline-to-baseline distance for the font.
metric_data_format	Always 0.
min_bottom_side_bearing	The minimum bottom side bearing of all glyphs within the font.
min_top_side_bearing	The minimum top side bearing of all glyphs within the font.
number_of_vmetrics	Number of VMetrics entries in the ‘hmtx’ table – this value can be smaller than the total number of glyphs in the font.
