[pdftex] Fonts in multiple pdf images

[Ricardo Sanchez Carmenes]

Hi!

Sorry if this has already been asked and replied.

Using \pdfximage, I am integrating quit a number of pdf files
that consist mainly of text. They all use the same 4 or 5 fonts.
However, the resulting file is quite huge, as the same font is
incorporated at every instance in the resulting file.

Is there a way to avoid this, so that fonts that are already
incorporated are not incorporated again with new pdf images
that make use of them ?

Thanks,
Ricardo.
