New Features

Split Route

This release brings a new multipart/form-data route for splitting PDF files:

POST /forms/pdfengines/split

It accepts the following form fields:

Key	Description	Default
splitMode	Either intervals or pages.	None
splitSpan	Either the intervals or the page ranges to extract, depending on the selected mode.	None
splitUnify	Specify whether to put extracted pages into a single file or as many files as there are page ranges. Only works with pages mode.	false

Thanks @​ps73, @​nodecentral, @​markitosgv, @​wjkoh!

Split Chromium PDFs

The multipart/form-data routes from the Chromium module also accepts the previous form fields for splitting the resulting PDF.

Split LibreOffice PDFs

In the same manner, the multipart/form-data route from the LibreOffice module accepts the previous form fields for splitting the resulting PDFs.

Chore

• Updates Chromium to version 131.0.6778.204/139 (except for armhf).
