You wrote the following code to do it:
public static int getPageNumberFromNamedDestination(PDDocument doc,
String name) throws IOException {
PDDestinationNameTreeNode dests =
doc.getDocumentCatalog().getNames().getDests();
if (dests==null || dests.getNames()==null)
return -1;
Object d = dests.getNames().get(name);
if (d==null)
return -1;
return getPageDestPageNumber(d);
}
public static int getPageDestPageNumber(Object dest) {
if (dest instanceof PDPageFitDestination) {
PDPageFitDestination pageFitDestination =
(PDPageFitDestination) dest;
return pageFitDestination.findPageNumber();
}
if (dest instanceof PDPageXYZDestination) {
PDPageXYZDestination pageXYZDestination =
(PDPageXYZDestination) dest;
return pageXYZDestination.findPageNumber();
}
if (dest instanceof PDPageFitWidthDestination) {
PDPageFitWidthDestination fitWidthDestination =
(PDPageFitWidthDestination) dest;
return fitWidthDestination.findPageNumber();
}
if (dest instanceof PDPageFitHeightDestination) {
PDPageFitHeightDestination fitHeightDestination =
(PDPageFitHeightDestination) dest;
return fitHeightDestination.findPageNumber();
}
if (dest instanceof PDPageFitRectangleDestination) {
PDPageFitRectangleDestination pageFitRectangleDestination =
(PDPageFitRectangleDestination) dest;
return pageFitRectangleDestination.findPageNumber();
}
return -1;
}
