5-6 Merging Fonts

If you specify to merge fonts during PDF optimization processing using Antenna House PDF API, duplicate font information will be merged.

Merging fonts has the following conditions:

• Merging fonts is done for fonts embedded in the PDF.
• The following fonts are to be integrated.
  • TrueType, Type1 (CFF format only), CIDFontType2, CIDFontType0
• Even if the font type is the same, if the Font dictionary values (Ascent, CapHeight, etc.) are different, they will not be merged.
• TrueType fonts and CIDFontType2 fonts are subject to be merged only if the cmap, head, hhea, hmtx, maxp, cvt, fpgm, and prep tables are the same.

For details on how to actually specify merging fonts using commands, see Chapter.12 of this manual, "12-13 -optimize: Optimizing PDF Files."
