I am trying to write a simple application fixing a flawed PDFs (delete
unwanted pages, patch or create ToC - I mean the outline tree). So far, I have
a Qt4 - PoDoFo - MuPDF app, which can read and display a PDFs. Thus, set
out...
Task #1, delete ToC completely because we will create ToC from scratch. First
attempt:
PoDoFo::PdfMemDocument *doc = new PoDoFo::MemDocument;
<load ok>
PoDoFo::PdfOutlines *root = doc->GetOutlines(false);
if( root != nullptr ) root->Erase(); // GP fault
Okay, PdfOutlines is a derived class from PdfOutlineItem and I have already
found out that it may be incomplete (for example, it has no label). Next
attempt (delete outline items, not the root):
if( root != nullptr )
{
PoDoFo::PdfOutlineItem *toc1 = toc->First();
PoDoFo::PdfOutlineItem *toc2 = nullptr;
while( toc1 != nullptr )
{
toc2 = toc1;
toc1 = toc1->Next();
toc2->Erase(); // GP fault
}
Why?
The PDF is a small PDF 1.2. Operating system is Debian Wheezy KDE, PoDoFo
0.9.1 (from the Debian repository). Memory 8 GB. It is known that the PDF has
outline destinations defined by /GoTo actions.
