I trying to get the contents of a PDF annotation to string so I can store that information in a database for searching purposes.
Does anyone know how to accomplish this
Yes, but the specifics really depend on what kind[s] of annotations you're talking about.
In general:
PdfDictionary pageDict = myPdfReader.getPageN(firstPageIsOne);
PdfArray annotArray = pageDict.getAsArray(PdfName.ANNOTS);
for (int i = 0; i < annotArray.size(); ++i) {
PdfDictionary curAnnot = annotArray.getAsDict(i);
int someType = myCodeToGetAnAnnotsType(curAnnot);
if (someType == THIS_TYPE) {
writeThisType(curAnnot);
} else if (someType == THAT_TYPE) {
writeThatType(curAnnot);
}
}
For details, you'll need to examine the PDF Specification, in particular the annotation descriptions: "Chapter 12.5.6 Annotation Types".
If you can tell us what types you care about, I can be of more help.
