Pdfstitcher

First alpha testing version that includes line property modification and layer selection.

Latest stable release as of December 18 2020.

Bug fixes: Updated Dutch language file, improved error handling for locale issues. Fixed locale definition so that administrator privileges are not required.

Reported to work on 64-bit Windows 7 and Windows 10.

MacOS was built on High Sierra and has been tested on Catalina. Unfortunately not working on older systems (e.g. El Capitan).
Language detection is not working correctly in Mac, but separate apps have been created for supported languages. These can be downloaded below under "Assets" with the suffix _lang (e.g. _fr for French, _de for German, etc).

Adding optional trim or overlap, with bug fix for trimming.

Outstanding issues: language support on OS X is not working correctly unless run through Terminal.

Adding support for German, Dutch, French, Spanish (language switches based on system settings) on Windows. Localization in Mac version not yet working.

Pages are now trimmed instead of simply overlapped.

First release using pikepdf instead of PDFTron in backend. Now 100% open source!
Also first release with an app bundle for mac.
