ackee-svg-converter

Simple SVG => PDF converter

Installation

Converter uses Google's Puppeteer library which installs headless Chrome.

For merging PDFs it also needs pdftk installed.

Install Puppeteer on Debian/Docker's node image

On Debian (and thus also on Docker node image, which is Debian-based) you will need to manually install the following dependencies:

#!/bin/bash 
 
apt-get update
apt-get install -yq gconf-service libasound2 libatk1.0-0 libc6 libcairo2 libcups2 libdbus-1-3 \
  libexpat1 libfontconfig1 libgcc1 libgconf-2-4 libgdk-pixbuf2.0-0 libglib2.0-0 libgtk-3-0 libnspr4 \
  libpango-1.0-0 libpangocairo-1.0-0 libstdc++6 libx11-6 libx11-xcb1 libxcb1 libxcomposite1 \
  libxcursor1 libxdamage1 libxext6 libxfixes3 libxi6 libxrandr2 libxrender1 libxss1 libxtst6 \
  ca-certificates fonts-liberation libappindicator1 libnss3 lsb-release xdg-utils wget
