I managed to figure out a partial solution after studying the PdfReader
implemenation on sourceforge.net. Removing or overwriting a specific
attachment appears to be quite a bit more involved. If you have a solution
for that, please post it here.
public void removeAttachments(PdfReader reader)
{
PdfDictionary catalog = reader.getCatalog();
PdfDictionary names = (PdfDictionary)
PdfReader.getPdfObject(catalog.get(PdfName.NAMES));
if( names != null )
{
PdfDictionary files = (PdfDictionary)
PdfReader.getPdfObject(names.get(PdfName.EMBEDDEDFILES));
if( files != null )
{
for( Object key : files.getKeys() )
{
files.remove((PdfName)key);
}
}
}
}
