fonttosfnt - Wrap a bitmap font in a sfnt (OpenType) wrapper


fonttosfnt [ options ] -o file.otb [ -- ] [ font ] ...


Wrap a bitmap font or a set of bitmap fonts in a sfnt (TrueType or OpenType) wrapper. If no font is specified, a BDF font is read from standard input (stdin).


Be verbose.
Do not crop glyphs. This usually increases file size, but may sometimes yield a modest decrease in file size for small character cell fonts (terminal fonts).
Write byte-aligned glyph data. By default, unaligned data is written, which yields a smaller file size.
Do not reencode fonts. By default, fonts are reencoded to Unicode whenever possible.
Set the type of scalable glyphs that we write. If n is 0, no scalable glyphs are written; this is legal but confuses most current software. If n is 1, a single scalable glyph (the undefined glyph) is written; this is recommended, but triggers a bug in current versions of FreeType. If n is 2 (the default), a sufficiently high number of blank glyphs are written, which works with FreeType but increases file size.
Set the type of scalable metrics that we write. If n is 0, no scalable metrics are written, which may or may not be legal. If n is 1, full metrics for a single glyph are written, and only left sidebearing values are written for the other glyphs. If n is 2, scalable metrics for all glyphs are written, which increases file size and is not recommended. The default is 1.
End of options.


Some of the font-level values, notably sub- and superscript positions, are dummy values.
