absoluteX/absoluteY of columns block not working now

[Feofilakt]

Hello. I suspect that absoluteX/absoluteY of columns block not working after update. Its not floating on top of the map.

If the absoluteX, absoluteY and width are given, the columns block will be floating on top of the page at the specified position.

After which update, please be specific with a version numbers?

There was a change from iText to OpenPDF in order to respect GPL license restrictions in GeoServer, GeoNode. As part of changing PDF engine some functionality may not be working as intended.

Update from https://github.com/mapfish/mapfish-print to https://github.com/mapfish/mapfish-print-v2.
Yes, guess the problem is OpenPDF. I even seem to find the bug:

[jodygarnett]

i am not understanding as i am just being a build person n this project, can you make a PR please?

that said we are making a release very soon for geotools api change and java 11

I believe you are indicating this is a bug in OpenPDF based on the screen snap provided.

The code remains unchanged https://github.com/LibrePDF/OpenPDF/blob/master/openpdf/src/main/java/com/lowagie/text/pdf/PdfDocument.java#L1234

        // If the current line is not null
        if (line != null) {
            // we check if the end of the page is reached (bugfix by Francois Gravel)
            if (currentHeight + line.height() + leading < indentTop() - indentBottom()) {
                // if so nonempty lines are added and the height is augmented
                if (line.size() > 0) {
                    currentHeight += line.height();
                    lines.add(line);
                    pageEmpty = false;
                }
            } else {
                // if the end of the line is reached, we start a new page
                newPage();
            }
        }

Did you have a follow up action with OpenPDF? Is there something we can do to mitigate in the map fish-print-v2 codebase?

[Feofilakt]

Hello! No, I've not did anything with OpenPDF. Not sure if it possible to mitigate in this codebase, I've just solved it by decreasing block height by 1 (so it like (100 + 99) / 200 instead of (100 + 100) / 200).
