    - #### TTFReader

          public TTFReader()

      Main constructor.

  - ### Method Detail

    - #### main

          public static void main(java.lang.String[] args)

      The main method for the TTFReader tool.
      Parameters:
        `args` - Command-line arguments: [options] fontfile.ttf xmlfile.xml where options can be: -fn default is to use the fontname in the .ttf file, but you can override that name to make sure that the embedded font is used instead of installed fonts when viewing documents with Acrobat Reader. -cn default is to use the fontname -ef will add the possibility to embed the font. When running fop, fop will look for this file to embed it -er you can also include the fontfile in the fop.jar file when building fop. You can use both -ef and -er. The file specified in -ef will be searched first, then the -er file. -nocs if complex script features are disabled

    - #### loadTTF

          public TTFFile loadTTF(java.lang.String fileName,
                                 java.lang.String fontName,
