TL;DR  

A docker-container that watches for incoming files (incrond) and merges them together

 (using [qpdf](http://qpdf.sourceforge.net)) if needed.  

The reason I created this project, is a scanner (HP OfficeJet) whose duplex unit sucks.

It can’t handle folded sheets well (paperjam in 8 out of 10 cases).

So I need to scan the odd and even pages separately and merge them together afterwards.  

The docker-container is running on my NAS (QNAP TS-251+) and watches for new files in a mounted volume,

in which the scanner saves it files. The files are prefixed based on scan-profiles and merged based on

these prefixes.  

For convenience I reverse the order of the even pages and rotate them by 180 degree during the

merge process. Doing that I can simply take the scanned pages from the output

tray and put them back to the input feeder without the need to rotate and reorder them.

## Example usage:

```console

> docker pull rverst/pdfmerge

> docker run -v /scan_folder:/input \

             -v /scan_folder:/output \

             rverst/pdfmerge:latest

```

Note that the script runs as UID 1000 and GID 1000 by default. These may be altered with the PUID and PGID environment variables.

## Environment variables:

 * PUID - UID to use

 * GUID - GID to use

 * WAIT_TIMEOUT - timeout in sec. the script waits for a file to close. Should not be to short since some scanners

 create the file at the beginning of the scan.

 * ROTATE_ODD - rotate the odd pages

 * ROTATE_EVEN - rotate the even pages

 * REVERSE_EVEN - reverse the order of the even pages
