I'm using iTextPDF + FreeMarker for my project. Basically I load and fill an HTML template with FreeMarker and then render it to pdf with iTextPDF's XMLWorker. The code works fine, but I have a problem with variable heights.
Let's say that we have data like this:
errorId = "ERROR-01"; systemId = "SYSTEM-01"; description = "A SHORT DESCRIPTION OF THE ISSUE"
But if the data looks like this:
errorId = "ERROR-01"; systemId = "SYSTEM-01"; description = "A SHORT DESCRIPTION OF THE ISSUE. THIS IS MULTILINE AND IT SHOULD STAY ALL IN THE SAME PDF PAGE."
As you can see, I now have two pages. I would like to have only one page that changes its height according to the content height.
You can not change the page size after you have added content to that page. One way to work around this, would be to create the document in two passes: first create a document to add the content, then manipulate the document to change the page size. That would have been my first reply if I had time to answer immediately.
Now that I've taken more time to think about it, I've found a better solution that doesn't require two passes. Please take a look at HtmlAdjustPageSize
For testing purposes, I used static
String values for HTML and CSS:
public static final String HTML = "" + """ +
