• GhostScript is used to convert PDF to PDF/A format but but has a bug that results in slow conversion, poor rendering and large resulting files.
• using gif format files instead of png avoids this issue

Please read this page if you would like to consume this service on MDTP

POST /pdf-generator-service/pdf-generator/generate

All requests use the HTTP POST method

* Generates a PDF based on the submitted html
* Generated PDF must be PDF/A 1 or PDF/A 2 compliant
* Generated PDF must match the HTML page from which it was generated

* html-www-urlencoded-form with a single field 'html' that contains the html to be converted

* HTTP 200 OK with a generated and downloadable PDF
* HTTP 400 Bad Request for invalid/error scenarios

• Install wktohtml https://wkhtmltopdf.org/downloads.html version 0.12.3
• Install Ghostscript https://ghostscript.com/
• Check alias for ghostscript is ```gs
• Check parameters in application.conf after "PdfGenerator Service config - use these values for local running only"

To run the application execute

sbt ~run 9852

The endpoints can then be accessed with the base url http://localhost:9000/pdf-generator-service/pdf-generator/generate

This command will install ghostscript:

sudo apt-get install ghostscript

This command will install wkhtmltopdf:

sudo apt-get install wkhtmltopdf

We then need to add this symbolic link so that the service finds the program:

sudo ln -s /usr/bin/wkhtmltopdf /usr/local/bin

If you need to check the logs of the generator service, you may find it useful to use this command to remove the graphite warnings:

sm --start PDF_GENERATOR_SERVICE --appendArgs '{"PDF_GENERATOR_SERVICE":["-Dmicroservice.metrics.graphite.enabled=false"]}' -f

This command will bring up the logs of the pdf-generator-service:

sm --logs PDF_GENERATOR_SERVICE
