![]() The minimum right side bearing of all glyphs within the font. The minimum left side bearing of all glyphs within the font. It can be used to compute the maximum width of an arbitrary string of text. This field is the maximum of all advance widths found in the font. 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. You should use the sTypoDescender field of the ‘OS/2’ table instead if you want the correct one. The font's descender, i.e., the distance from the baseline to the bottom-most of all glyph points found in the font. You should use the sTypoAscender field of the ‘OS/2’ table instead if you want the correct one. ![]() This value is invalid in many fonts, as it is usually set by the font designer, and often reflects only a portion of the glyphs found in the font (maybe ASCII).
