|
|
application/pdf
|
|
pdftotext -nopgbrk %s - | sed -e 's/ [a-zA-Z0-9.]\{1\} / /g' -e 's/[0-9.]//g'
|
|
|
|
If pdftotext takes too long on large document you may want to pass parameter
|
|
-l to specify the last page to be converted
|
|
|
|
mutool draw -F txt -q -N -o - %s

|
|
xls2csv -d tab %s
|

|
|
html2text %s
|
|
|
|
Many office formats
|
|
unoconv -d document -f txt --stdout '%s'
|
|
|
|
Apache Tika is another option for creating plain text from various document
|
|
types. Just use curl to send the document to your tika server and get the
|
|
plain text in return.
|
|
|
|
curl -s -T '%s' http://localhost:9998/tika --header 'Accept: text/plain'

Conversion to png for preview images
|
|
=====================================
|
|
|
|
If you have problems running convert on PDF documents then read this page
|
|
https://askubuntu.com/questions/1081895/trouble-with-batch-conversion-of-png-to-pdf-using-convert
|
|
It basically instructs you to comment out the line
|
|
|
|
<policy domain="coder" rights="none" pattern="PDF" />
|
|
|
|
in /etc/ImageMagick-6/policy.xml
|
|
|
|
convert determines the format of the converted image from the extension of
|
|
the output filename. SeedDMS usually sets a propper extension when running
|
|
the command, but nevertheless it is good practice to explicitly set the output
|
|
format by prefixing the output filename with 'png:'. This is of course always
|
|
needed if the output goes to stdout.

On Linux systems you will have to set the desired value in /etc/papersize for a2ps
|
|
e.g. a4, or letter

This will take 12th frame of a video and converts into a png. It requires
|
|
ffmpeg to be installed.
