title: consolidate the fonts between merges pdfs itextsharp C#
body: <p>I need to merge multiple pdfs together.  I am using itextsharp to create all the pdfs.  I need to reduce the size of the pdfs to the lowest possible size.  I know the fonts are being duplicated for each pdf.  Is there to use only one set of fonts throughout the merged pdf?  For example,  pdf1 is 2.8mb and pdf2 is 2.8 mb I merge them together and its about 5.7mb.  I know for a fact that both of those pdfs are using the same font but the data for the font is being duclpicated even though its in the same pdf.</p>
  
  <p>I tried using setting the compression properties to best compression and set full compression and that barely reduced the size.  </p>
  
  <p>Though when i ran the pdf through Acrobat X pro and optimize its reduce almost 90%+ from like 160 mb to 5 mb.  The usage audit says its 90% of the pdf is fonts before optimizing.</p>
  
  <p>Now is there a way to consolidate the fonts between merges pdfs ?</p>
