System Requirements

The system requirements depends on the requirements of the compared PDF files, that means the complexity of the PDF files and also the number of pages, images etc. The following requirements are primarily for the i-net PDFC server.

Minimum System Requirements

Installed Server / Desktop Application

The following 64-bit operating systems are supported:

  • Windows 7 or above
  • Windows Server 2012 or above
  • Ubuntu 18.04
  • RedHat 6.x or 7.x
  • macOS 10.10 or above

Installation on other Operating Systems

Installing the i-net PDFC server on other operating system is generally supported when a supported Java VM is available. In that case, please download the respective SDK.

Note: custom startup scripts will have to be created as there is no automatic configuration.

Docker

Running i-net PDFC in a Docker container is supported. Please check the website for technical license requirements.

Application Server

Application Server implementing the Servlet Specifications 3.1 including WebSocket 1.1 are supported. They have to be run using at least Java EE 7 (Java 8).

SDK (Java)

Java SE 8 or 11 is required to use the Java API of i-net PDFC.

SDK (.NET)

Requires .NET Framework 4.6.1 and Java SE 8 or 11.

Memory

The minimum hardware requirements are 1.5 GB hard disk for a full installation. This includes 500 MB installation directory and 1 GB for the Temp directory of the system.

CPU

The recommended minimum number of CPU in a virtual machine is 4. It use 2 cores for the parser of the PDF files, 1 core for the comparison process and maybe 1 core for the paging of the result.

Supported browser versions

The remote interface was tested with the following browsers: Internet Explorer 11, Microsoft Edge, Firefox, Safari and Chrome. We recommend the most recent browser versions.

Additional Information

Requirements can be higher if you compare large PDF files with a lot of pages, images and/or a lot of users comparing the PDF files.

In addition to the product requirements, please note the System Compatibility list for Java 11 by Oracle: https://www.oracle.com/technetwork/java/javase/documentation/jdk11certconfig-5069638.html.

OCR using Tesseract

The OCR is done using the Tesseract libraries. Operating Systems other than Windows require the libraries to be installed before starting the i-net PDFC Server.

There is a specific plugin supporting Tesseract on Windows directly without extra installation. However, it might still fail to initialise due to processor architectures. In that case an installation of the tesseract binaries should work.

For installations of Tesseract, please see the official page at https://github.com/tesseract-ocr/tesseract/wiki and check the requirements.

Note: Setting up Tesseract in Docker Container requires the configuration of a custom layer.
