URL: https://issues.apache.org/jira/browse/PDFBOX-1188
Project: PDFBox
Issue Type: Bug
Components: PDModel
Reporter: William Fausser
Priority: Minor
Fix For: 1.7.0
For some PDF/A, getDictionaryObject does not return COSStream but other
COSDictionary (super class)
public PDMetadata getMetadata()
{
PDMetadata retval = null;
COSStream mdStream = (COSStream)stream.getDictionaryObject(
COSName.METADATA );
if( mdStream != null )
{
retval = new PDMetadata( mdStream );
}
return retval;
}
