Below are the options for TTCap, to use with XTT or FreeType in Linux to make TrueType fonts works.

  • fn - face number (int)
  • ai - slant rate (real)
  • fp - font metric calicurate (y/n) – note: maybe obsolated by fs?
  • fs - force spacing (p/m/c)
  • bw - width rate (real), valid for fixed fonts only
  • ds - double striking, i.e. pseudo bold (y/n)
  • vl - very lazy method to caliculate metrics (y/n)
  • eo - code conversion module name (string)
  • hi - hinting (y/n)
  • cr - restrict code range for unicode fonts (range,range,… where range is a or a-b or -b or a-)
  • eb - use embedded bitmaps (y/n), use only with bs but not recommended with vl or eb
  • bs - embedded bitap bounding box width rate (real)
