itextsharp

问题 I am trying to create a PDF based on some vector art I have in my C# application. I have two major problems when I try to map the points and types from a GraphicsPath. Some paths are just plain missing. When a sub path is an internal boundary I need to indicate that somehow. ie, the circle in the letter d is filled in. I'm referencing iTextSharp 5.5.2 on NuGet.

问题 I have a PDF form with a number of text fields. The values entered in these fields are used to calculate values in other fields (the calculated fields are read-only). When I open the form in Adobe Reader and fill in a field, the calculated fields automatically re-calculate. However, I am using iTextSharp to fill in the fields, flatten the resulting form, then stream the flattened form back to the user over the web. That part works just fine except the calculated fields never calculate. I'm
