Create PDF/A with Java (itext5) смотреть онлайн

There are many good programming tutorials on Youtube, but I found that most of them are very long and not to the point. I decided to open a YT channel to upload precise & short videos to give some guided help.
I try to orient this channel to Stackoverflow, but with Videos.

Code: https://github.com/ProgrammingByPhilippOppel/pdfa

Textscript:
The first step in order to create a PdfA Document with Java is to initialize a Document Object and the PdfAWriter.
We cant have a PDF/A Doc without embedding the used font and a Color Profile.
So we declare them like this, keep in mind that those two need to be actual files.

The second step is to prepare the document, so it fits the conformance of PDFA. So we want to add our previously defined Colorprofile and XMP-Metadata to the document. This is done like so.

In the third step we actually place something inside the document, so we dont just have an empty document.
In order to do so we just create the element (I choose a Table) and add it to the document. There is no big magic behind that, but always remember to reference your font when using text, like I did with the Phrase Object, otherwise it wont compile and you get a conformance exception.

Finally we must close the document. You can do this outside of the try-catch, but its more clean to do so within a finally, because this way you can guarantee that you wont create a zombie document.

Now lets see the document... and as you can see the conformance is pdf/a.

Thank you for watching, if you liked the video leave a like. See you next time.
