Description
问题出在 \iTextSharp\core\iTextSharp\text\pdf\PdfReader.cs 的Flate解压缩函数
internal static byte[] FlateDecode(byte[] inp, MemoryStream outS)
//不能直接使用outS，会被close，导致下一句无法执行。
byte[] b = FlateDecode(inp, true, new MemoryStream(outS.ToArray()));
itext-dotnet 在 FlateDecodeFilter.cs#L44 里已经改成不释放了。也不一定好。
