[RESOLVED] PDF compression

[Precision999]

Hi

I realise this may not be the most appropriate place to ask this, so apologies - but at least I might get a point in the right direction?

I've been using the itextsharp library in a project to split a pdf into separate sheets, rename the parts, and then re-assemble them. Some of the pdfs I've been running have been 3000-5000 pages long with graphics and text.

The split/join process works well enough, but the resulting re-joined pdf is inflated. With the original of 57mb, the output is 880mb. That's with a file of 3300 or so pages.

Acrobat DC can sort this out just by opening the pdf and saving as a new file - it reports that it 'consolidates duplicate page backgrounds' and 'consolidates duplicate fonts' as it saves and by doing that I get the file size down to pretty much the original 57mb.

Does anyone have a good means of doing this sort of compression from vb? - the ways I've tried so far don't make much of a saving on the file size.

I have no budget for this, so I'd need to be able to do this without buying the Acrobat SDK!

Thanks!


UPDATE- just check the fonts in the joined doc and there are 6412 of them! - I reckon all but 6 or 7 are superfluous!
