Jorge Spinsanti commented on PDFBOX-4780:
-----------------------------------------
Ok [~tilman], but I'm not sure about we should work with these corrupt files.
If I have 10 files to merge and one of them is corrupt, the merge between 10
files fails. So, we are trying to fast analysis on each file to prevent
different exceptions thrown by PDFBox code.
Perhaps you can add some validation in PDDocument class and we can invoke
explicitly. In this case,
{code}
try (PDDocument pdDocument = PDDocument.load(file)) {
...
}
{code}
was not enough.
We try to prevent this issue doing
{code}
try {
...
for (PDPage page : documentCatalog.getPages()) {
for (PDAnnotation ann : page.getAnnotations()) {
ann.getCOSObject().removeItem(COSName.STRUCT_PARENT);
}
}
...
} catch (Exception e) {
...
}
{code}
Make sense?
