[jira] [Commented] (PDFBOX-4117) Implement GoToE action-type

["Gilad Denneboom (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/PDFBOX-4117?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17561737#comment-17561737 ] 

Gilad Denneboom commented on PDFBOX-4117:
-----------------------------------------

I'm back to this class and am having issues using it to link to a specific page of an embedded PDF file.

When I try to use setPageNumber on the PDDestination object I get the following error message:

 java.lang.IllegalArgumentException: Destination of a GoToE action must be a page dictionary object

However, I don't see a way to get a reference to the PDPage object for the target page so I could use it with setPage.

I think the implementation of this class needs to be adjusted to allow specifying only a page number, not a Page object.

Acrobat does that when you create such links manually. The COSArray under D contains a page number reference in the first item, not a page reference.

> One of the major Action Types is not implemented in any version of PDFBox, and I believe it should be. I'm referring to "Embedded Go-To Actions" (defined under 12.6.4.4 in PDF 32000-1:2008), which allows a link to open an attached file. Currently, such "GoToE" actions are interpreted as "null" by PDFBox, which is not ideal.
