[GTALUG] tip: creating compact PDFs from LibreOffice

I have a document with pictures. I printed it to PDF from LibreOffice. The result was 20MB: too big to mail. I used a program called "shrinkpdf" to shrink the PDF. There are no options. The size was 128k. It was a bit fuzzy. Then I found out that LibreOffice's export to PDF lets you control the resolution and clarity of pictures. The default setting gave me 333k. It looked much better than the output of shrinkpdf. Conclusion: LibreOffice's export to pdf is usefully different from printing to PDF.
