Tilman Hausherr commented on PDFBOX-4197:
-----------------------------------------
Do you mean this part?
{code}
COSBase item = it.next();
if (item instanceof COSDictionary)
{code}
I'd change it to
{code}
COSBase item = it.next();
if (item instanceof COSObject)
{
item = ((COSObject) item).getObject();
}
if (item instanceof COSDictionary)
{code}
> PDStructureElement.getAttributes() ignores reference objects

> Key: PDFBOX-4197
> URL: https://issues.apache.org/jira/browse/PDFBOX-4197
> Project: PDFBox
> Issue Type: Bug
> Components: PDModel
> Affects Versions: 2.0.9
> Environment: N/A
> Reporter: Bill Janssen
> Priority: Major
> Original Estimate: 4h
> Remaining Estimate: 4h
>
> Attribute dictionaries attached to a structure element may be either direct
> or references. getAttributes() handles the direct case but ignores object
> references without error messages. This can also lead to invalid revision
> numbers attached to the attribute dictionaries it does handle properly.
>
> The fix would be to add another branch to the iteration loop in
> PDStructureElement.getAttributes(), to handle object references.
