Hi!

I have a PDF file with an embedded font. I am merging two copies of
this PDF. What I get is a big PDF file which is twice the size of the
original. It looks like the merge put twice the font in the file. Is it
normal? Why doesn't he detect that it's the same embedded font and put
it only once in the file? By the way I'm using VB.NET with PDF4NET
component. I don't know if it's a problem with the component or it a
PDF standard. When I'm merging many PDF files, I get big size files,
it's a big problem for us.

Someone has a clue for this?

Thanks!

Jeff

Try doing a "save as". This generally results in a substantial reduction in 
file sizes.

Not sure how to do it with PDF4NET

Jeff,

tipically pdf "libraries" does not optimize the resulting pdf. It's not
very easy to check if 2 embedded fonts are the same font and remove one
of them. But it's not impossible: try multivalent
(http://multivalent.sourceforge.net/) or PdfLib PLOP
(http://www.pdflib.com/products/plop/index.html). They could be
usefull....
