PDF Stitcher

The PDF Stitcher library allows you to easily stitch together multiple PDFs into a single file.

Installation

To install the PDF Stitcher package, run the following Composer command.

composer require langleyfoxall/pdf-stitcher

Please note that this package requires Ghostscript (gs) to be installed on your server. If you are running Ubuntu, this can be installed with the following command.

sudo apt install ghostscript

Usage

See the following basic usage example.

(new PdfStitcher)
    ->addPdf('firstDocument.pdf')
    ->addPdfs(['secondDocument.pdf', 'yetAnotherDocument.pdf'])
    ->save('destinationDocument.pdf');

This will take in three input PDFs, stitch them together, and save out the result to destinationDocument.pdf. The documents will be stitched together in the order they are added.

Where Ghostscript is in an unusual location

A path to a Ghostscript executable can be passed into the PdfStitcher constructor:

new PdfStitcher('a/path/to/a/gs/executable')

Additional Ghostscript arguments

Additional Ghostscript arguments can be passed into the PdfStitcher constructor:

new PdfStitcher(null, '-dNEWPDF=false')

These will NOT be escaped in any way.

Including only specific pages from a PDF

You may optionally give an array of page indices when adding a PDF:

(new PdfStitcher)
    ->addPdf('firstDocument.pdf', [0, 2, 3, 5])
    ->save('destinationDocument.pdf');

Only the page numbers you list will be included.

The following will be rejected:

• Non-integer page numbers.
• Page numbers less than zero.
• Duplicate page numbers (e.g. 1, 3, 3, 5, 7).
• Misordered page numbers (e.g. 1, 5, 3, 7).
