1) djvu bigger than PDF. As I understand it, djvu is "an image compression technology". PDF is a portable document format. PDF can store text as character strings and the viewer can render those strings using external or embedded fonts. PDF can include compressed bitmaps of scanned text but that isn't the only way it can store text. If you take a PDF where ...

From Princeton WordNet: S: (n) pagination, folio, page number, paging (the system of numbering pages) That explains the whole shebang.

I started a Bash project on github to help convert from PDF to PDF+OCR and DjvU+OCR. It's based on the reply by @meda-beda and some edit I added. It is a wrapper of pdfSandwich and pdf2djvu. It was developed and tested under Ubuntu-12.10, I reckon there is still work to do on the option to tweak the resulting file (sometimes bigger than original).

I had a similar issue with other package managers before. Make sure you're up to date with the package information and the package manager itself. Use sudo port selfupdate to do this for MacPorts. If you only want to update the package information, use sudo port sync.

PDF's are largely comprised of vector elements and AI treats them as vector (e.g., you can open/edit/save). Yes, they can contain raster elements, but it treats them as vectors and attempts to scale them as it does embedded fonts and illustrations. Call it a hybrid if you will, but the raster support is more a concession than original intent.
