Hi,
thanks for help!
I could finally try the 3.0.1-SNAPSHOT version, an hour ago. The main issue
with garbage text on the pdf/table's header line, was solved, this looks ok.
There are some other problems, all related to the flatten() method.
One is, that images added to a pdf form are converted to a PDPushButton
component on the AcroForm, and then they are subject to flatten.
Version 2.0.29 correctly removes them from the form, and adds the image to
the content stream.
Version 3.0.0, and also 3.0.1-SNAPSHOT produces a pdf with missing images.
I added a filtering, so these are filtered from flatten call:
private static List<PDField> filterPDPushButtonFields(PDAcroForm form) {
return
form.getFields().stream().filter(checkBeingPdPushButton()).collect(Collectors.toList());
}
form.flatten(filterPDPushButtonFields(form), false);
this looks ok, regarding the image.
I re-tested these with 3.0.1-SNAPSHOT, and it has text distorted, letters
badly positioned:
[image: distorted-text.png]
I am using the following to load the template pdf:
InputStream resourceAsStream = ...
PDDocument a1doc = Loader.loadPDF(new RandomAccessReadBuffer(
resourceAsStream), () -> new ScratchFile(MemoryUsageSetting.
setupTempFileOnly()));
Original code used tempfile only for buffering the pdf load, I tried to
imitate it. When the errors popped up, also tried to use
RandomAccessReadBuffer, and it had no effect on the problems, so I set back
using tempfile.
PDAcroForm form = a1doc.getDocumentCatalog().getAcroForm(null);
intentionally using the null parameter to prevent fixups running, so new
behavior does not change much.
