Maximum runtime memory use depends on the maximum band size of any bitmap potentially rasterized by the font scaler. Maximum memory usage is minimum memory usage plus maximum runtime memory use. The driver will still work but will be less efficient. If it is not known, set the value to zero. This information should be supplied if known. The last four entries in the table are present because PostScript drivers can do better memory management if the virtual memory (VM) requirements of a downloadable OpenType font are known before the font is downloaded. Maximum memory usage when an OpenType font is downloaded as a Type 1 font. Minimum memory usage when an OpenType font is downloaded as a Type 1 font. Maximum memory usage when an OpenType font is downloaded. Minimum memory usage when an OpenType font is downloaded. Set to 0 if the font is proportionally spaced, non-zero if the font is not proportionally spaced (i.e. In general, the underline thickness should match the thickness of the underscore character (U+005F LOW LINE), and should also match the strikeout thickness, which is specified in the OS/2 table. Suggested values for the underline thickness. The value of the PostScript key may be calculated by subtracting half the underlineThickness from the value of this field. The PostScript definition of this FontInfo dictionary key (the y coordinate of the center of the stroke) is not used for historical reasons. This is the suggested distance of the top of the underline from the baseline (negative values indicate below baseline). Zero for upright text, negative for text that leans to the right (forward). Italic angle in counter-clockwise degrees from the vertical. OpenType fonts with CFF data use Version 3.0 only. OpenType fonts with TrueType data may also use Version 3.0. Versions 1.0, 2.0, and 2.5 refer to TrueType fonts and OpenType fonts with TrueType outline data. For more information about PostScript names, see the Adobe Glyph List Specification. This includes data for the FontInfo dictionary entry and the PostScript names of all the glyphs. This table contains additional information needed to use TrueType or OpenType™ fonts on PostScript printers.
