Andrea Vacondio updated PDFBOX-2704:
------------------------------------
Attachment: page_tree_multiple_levels.pdf
with_outline.pdf
page_tree_index_of.diff
I created a possible fix for this. I don't know if PDPageTree is under
development and maybe my fix won't be needed but I also included unit tests
that I think might be useful to test the indexOf behavior.
> PDPageTree.indexOf doesn't find page numbers

> Key: PDFBOX-2704
> URL: https://issues.apache.org/jira/browse/PDFBOX-2704
> Project: PDFBox
> Issue Type: Bug
> Components: PDModel
> Affects Versions: 2.0.0
> Environment: 2.0.0-SNAPSHOT r1665633
> Reporter: Andrea Vacondio
> Labels: PDPageTreee
> Attachments: bigger_outline_test.pdf, page_tree_index_of.diff,
> page_tree_multiple_levels.pdf, with_outline.pdf
>
>
> I know https://issues.apache.org/jira/browse/PDFBOX-2423 is not closed yet so
> I'm not sure if the issues I'm having are a cause of that.
> I'm using the latest trunk and I have issues with the PDPageTree.indexOf
> method. The javadoc reads ??Returns the index of the given page, or -1 if it
> does not exist.?? which I understand it means in returns -1 if the given page
> is not found in the page tree correct? If so, the following unit test fails:
> {code}
> @Test
> public void indexOfNotFoundPage() throws IOException {
> PDDocument doc1 = PDDocument.load(getClass().getClassLoader()
> .getResourceAsStream("pdf/bigger_outline_test.pdf"));
> assertEquals(-1, doc1.getPages().indexOf(new PDPage()));
> }
> {code}
> Another similar issue I have is that PDPageTree.indexOf doesn't find the
> correct index for a PDPage returned by the PDOutlineItem.findDestinationPage:
> {code}
> @Test
> public void indexOfPageFromOutlineDestination() throws IOException {
> PDDocument doc = PDDocument
>
> .load(getClass().getClassLoader().getResourceAsStream("pdf/bigger_outline_test.pdf"));
> PDDocumentOutline outline =
> doc.getDocumentCatalog().getDocumentOutline();
> for (PDOutlineItem current : outline.children()) {
> if (current.getTitle().contains("Second")) {
> assertEquals(3,
> doc.getPages().indexOf(current.findDestinationPage(doc)));
> }
> }
> }
> {code}
> Also note that indexOf is used by PDPageDestination.findPageNumber which also
> returns a wrong result.
