Hi Frank,
Thanks for your patience. I have received response from our development team. This issue WORDSNET-6396 is due to floating table at the first page of document. I am afraid your issue is still postponed due to some other important issues and new features. However, there is workaround for this issue. Please short the height of floating table as shown below:
Document doc = new Document(MyDir + "in.doc");
Table table = (Table) doc.GetChild(NodeType.Table, 0, true);
table.Rows[0].RowFormat.Height = table.Rows[table.Rows.Count - 1].RowFormat.Height - 10;
doc.Save(MyDir + "AsposeOut.pdf");
We apologize for your inconvenience.
