PDF (Command Line)

Gnome PDF

Compress

Thank you Alfred Klomp for this script…

Download shrinkpdf.sh from: http://www.alfredklomp.com/programming/shrinkpdf/

Move it to ~/bin/ and make it executable.

A sample command:

shrinkpdf.sh  setup.pdf out.pdf 100

Tip

The output resolution in this example is 100. The parameter is optional. The default resolution is 72 DPI.

Data

I haven’t tried https://github.com/measuresforjustice/textricator, but this article recommends it, Textricator: Data extraction made simple

Images

To extract PNG images from a PDF file:

pdftoppm briefing.pdf briefing -png

or:

pdfimages -j ..plan.pdf out

Will produce the following output:

ls
out-000.ppm  out-001.ppm  out-002.jpg

Note: PPM format is a lowest common denominator color image file format.

Pages

sudo apt-get install pdftk

pdftk myoldfile.pdf cat 1 2 4 5 output mynewfile.pdf
pdftk myoldfile.pdf cat 1-2 4-5 output mynewfile.pdf

Merge:

pdftk pg01.pdf pg02.pdf pg04.pdf pg05.pdf output mynewfile.pdf

Text

To extract text from a PDF file (I am not sure where pdftotext came from!):

pdftotext fundraising.pdf

Note

This command will create a fundraising.txt output file.
