          public MergeTTFonts(java.util.List<MergeTTFonts.Cmap> cmap)

  - ### Method Detail

    - #### createHmtx

          protected void createHmtx()
                             throws java.io.IOException

      Create the hmtx table by copying metrics from original font to subset font. The glyphs Map contains an Integer key and Integer value that maps the original metric (key) to the subset metric (value)
      Throws:
        `java.io.IOException` - on error

    - #### readFont

          public void readFont(java.io.InputStream is,
                               java.lang.String name,
                               FontContainer fontContainer,
                               java.util.Map<java.lang.Integer,java.lang.Integer> subsetGlyphs,
                               boolean cid)
                        throws java.io.IOException

      Returns a subset of the original font.
      Specified by:
        `readFont` in interface `MergeFonts`
      Parameters:
        `is` - font file
        `name` - name
        `fontContainer` - fontContainer
        `subsetGlyphs` - Map of glyphs (glyphs has old index as (Integer) key and new index as (Integer) value)
        `cid` - is cid
      Throws:
        `java.io.IOException` - in case of an I/O problem

    - #### scanGlyphs

          protected void scanGlyphs(org.apache.fop.fonts.truetype.FontFileReader in,
                                    java.util.Map<java.lang.Integer,java.lang.Integer> subsetGlyphs)
                             throws java.io.IOException

      Overrides:
        `scanGlyphs` in class `org.apache.fop.fonts.truetype.TTFSubSetFile`
      Throws:
        `java.io.IOException`

    - #### getMergedFontSubset

          public byte[] getMergedFontSubset()
                                     throws java.io.IOException

      Specified by:
        `getMergedFontSubset` in interface `MergeFonts`
      Throws:
        `java.io.IOException`

    - #### buildSubsetIndexToOrigIndexMap

          protected int[] buildSubsetIndexToOrigIndexMap(java.util.Map<java.lang.Integer,java.lang.Integer> glyphs)

      Get index from starting at lowest glyph position
      Overrides:
        `buildSubsetIndexToOrigIndexMap` in class `org.apache.fop.fonts.truetype.TTFSubSetFile`
