itextpdf | itextpdf freemarker 实现pdf的导出， 支持中文、图片以及外部样式 | Document Editor library

Your approach seems plausible: I imagine it could be improved by looping through all the overflow renderers (perhaphs, I will try it out and update the answer someday).

However, there is quite a different approach, which for me seems to be more convenient and accurate: why not to override ParagraphRenderer, so that leading is reset each time the corresponding Paragraph can not fit a page (and hence will be moved to the next page).

This is how such an extension class may look:

1. It seems that your SQL request doesn't return any row,

2. Put your PdfTable(3) out of your while();

This issue was resolved after I installed Eclipse Oxygen. Turns out it was plugin issue in the eclipse build that I had.

The problem was that EmptyContainer.sign method just gives out PDF bytes and not the authenticated attributes. The authenticated attributes are actually which needs to be signed. Thanks mkl for pointing in the right direction.

I modified EmptyContainer.sign method to create a PdfPKCS7 object and call PdfPKCS7.getAuthenticatedAttributeBytes with PDF hash as one of the arguments.

After signing the bytes returned by getAuthenticatedAttributeBytes() method and creating CMS container of the signed bytes and the original hash, I was able to successfully sign the PDF.

Here is the code if someone needs it. It is cluttered all over but you will get the essence.

iText 7.0 had a method add(String) for Cell.

For iText 7.1, as documented in the API, a Cell takes only a block element or an image for its add() method. Block elements in iText are things like paragraphs, lists and divs.

You can wrap your String in a Paragraph:

You cannot import a package like that in Java.

Import a specific class:

import com.itextpdf.text.pdf.PdfReader;

Or import a full package:

import com.itextpdf.text.pdf.*;

For the SetPageLabel method, both the first argument (numbering style) and the second (page label prefix) may be null, in order to omit them from the page labeling style.

To set a page label without numbering for page 4:

Unrelated to the issue of getting null, but doc.getXmpMetadata() returns a byte array. So you will not be able to print its content with

application-name is what you're looking for.
