With the following code I am trying to update Ink Annotations by first
removing them, then writing them with new InkList data.
However, when I read the file back, the InkList key is missing in the
dictionary - what am I missing?
PdfDocumentData::PdfSaveResult PdfDocumentData::saveAs(QString fileName)
{
QByteArray fn = fileName.toLocal8Bit();
try {
qDebug()<<"saving"<<fileName;
for(int pn = 0; pn < m_doc2->GetPageCount(); pn++) {
qDebug()<<"updating page"<<pn;
auto page = m_doc2->GetPage(pn);
for(int an = page->GetNumAnnots() - 1; an >= 0; an--) {
auto anno = page->GetAnnotation(an);
if(anno->GetType() == PoDoFo::ePdfAnnotation_Ink) {
page->DeleteAnnotation(an);
}
}
if(m_annotations.contains(pn)) {
QList<QList<QPointF> >& annots = m_annotations[pn];
for(int an = 0; an < annots.size(); an++) {
qDebug()<<"writing annotation"<<an;
QList<QPointF>& str = annots[an];
PoDoFo::PdfRect rect(0,100,100,0); //FIXME
auto anno = page->CreateAnnotation(PoDoFo::ePdfAnnotation_Ink, rect);
auto dict = anno->GetObject()->GetDictionary();
PoDoFo::PdfArray points;
for (int p=0; p<str.size(); p++) {
points.push_back(str[p].x());
points.push_back(str[p].y());
}
PoDoFo::PdfArray array;
array.push_back(points); // InkList is Array of Array of Points
dict.AddKey("InkList", array);
}
}
}
m_doc2->Write(fn.data());
} catch(...) {
qDebug()<<"exception saving"<<fileName;
return SaveError;
}
return SaveSuccess;
}
