PDF-Signer

A simple NodeJs application, which automatically adds signs to multiple pdf documents. Unfortunately it will never have a UI, so don't worry and just follow the Get Started Guide bellow.

Get Started

Step 1

Clone this project.

Step 2

Run yarn install to install all necessary dependencies.

Step 3

Create a files folder with 2 sub folders called input and signs on the root of the project.

pdf-signer
│── files
│   ├── input
│   ├── output
|   └── signs
|── src
.

`input`

Our pdf files, which get later signed by this application should be located here.

`signs`

The signs which will be used to sign our in input located pdf files should be located here. On Each pdf site a random sign from this folder will be put to increase the diversity a little. We recommend using signs in the same dimensions.

`output`

This folder gets automatically generated after executing this program. Here our signed pdf files will be located.

Step 4

Edit the drawImage function call, until the sign is on the wished position.

page.drawImage(signImage, {
    x: page.getWidth() / 2 - signImageDims.width / 2 - 100,
    y: page.getHeight() / 2 - signImageDims.height / 2 - 250,
    width: signImageDims.width,
    height: signImageDims.height,
 });

Step 5

Run yarn run start which automatically builds and executes the project. If everything went right, our signed pdf files are located in the generated output folder.

API

`combineIntoOnePdf`

If all signed pdf pages should be put into one single pdf file named after the combinedPdfName property.

const combineIntoOnePdf = true;
const combinedPdfName = "allBerichtshefte";
