Is there any examples about how to get the text in the Form XObject?
A New Bug:
When I use itextsharp to getPageContent, I got an Exception:
System.IO.EndOfStreamException: Trying to read content after the end of the stream
iTextSharp.text.pdf.RandomAccessFileOrArray.ReadFully(Byte[] b, Int32 off, Int32 len)
iTextSharp.text.pdf.PdfReader.GetStreamBytesRaw(PRStream stream,RandomAccessFileOrArray file)
iTextSharp.text.pdf.PdfReader.GetStreamBytes(PRStream stream,RandomAccessFileOrArray file)
iTextSharp.text.pdf.PdfReader.GetPageContent(Int32 pageNum,RandomAccessFileOrArray file)
iTextSharp.text.pdf.RandomAccessFileOrArray.ReadFully(Byte[] b, Int32 off, Int32 len)
iTextSharp.text.pdf.PdfReader.GetStreamBytesRaw(PRStream stream,RandomAccessFileOrArray file)
iTextSharp.text.pdf.PdfReader.GetStreamBytes(PRStream stream,RandomAccessFileOrArray file)
iTextSharp.text.pdf.PdfReader.GetPageContent(Int32 pageNum,RandomAccessFileOrArray file)
But there IS a picture(and nothing else) in the page and GetImportedPage runs well.
