PDF and image functions for Ignition scripts.

Artek-Utilities adds scripting functions for the PDF and image work Ignition does not do on its own: turn PDF pages into images a report can show, merge or split documents, shrink a PDF, and set a phone photo upright. It is free.

What it adds

Eleven functions in two groups

Each function takes file contents as a byte array, so it works on uploads, files read from disk and documents stored in a database. They are available in gateway, Designer and client scripts.

Where Artek Utilities fits Artek Utilities adds PDF and image functions to Ignition scripting on 8.1 and 8.3. Gateway, Perspective, Designer and Vision scripts call them with bytes and get bytes back, to save as files, store in a database or attach to reports and email. Ignition (8.1 or 8.3) Gateway scripts timers, events, WebDev Perspective scripts run on the gateway Designer and Vision script console, clients Artek Utilities PDF functions merge, split, watermark, compress, text and metadata, PDF to image Image functions resize, dimensions, fix photo orientation Your files and data bytes in, bytes out: files, database, reports, downloads, email
Scripts pass PDF or image bytes in and get bytes back.

Install

Installation takes four steps

  1. Download the build for your Ignition line and check its SHA-256.
  2. If an older Artek-Utilities module (io.artekis.Artek-Utilities) is installed, uninstall it first. This release replaces it.
  3. In the Gateway, open the module list: on Ignition 8.1, Config, then System, then Modules; on Ignition 8.3, Platform, then System, then Modules. Choose Install or Upgrade and upload the file.
  4. Accept the license and, the first time, the Artek, LLC certificate. The functions are then available to every script on the gateway.
