Trolltech gratefully acknowledges these and others contribution to Qt. We recommend that programs that use Qt also acknowledge these contributions, and quote these license statements in an appendix to the documentation.

    TrueType font support. These functions allow PPR to generate
    PostScript fonts from Microsoft compatible TrueType font files.

    The functions in this file do most of the work to convert a
    TrueType font to a type 3 PostScript font.

    Most of the material in this file is derived from a program called
    "ttf2ps" which L. S. Ng posted to the usenet news group
    "comp.sources.postscript". The author did not provide a copyright
    notice or indicate any restrictions on use.
