I'm using code similar to the following to read PDF files:- using (PdfDocument X = PdfReader.Open(FileName, PdfDocumentOpenMode.ReadOnly)) { foreach (PdfPage Page in X.Pages) { CSequence C1 = default(CSequence); C1 = PdfSharp.Pdf.Content.ContentReader.ReadContent(Page); // <<- Exception thrown in this method ... } } Up to now I've had no trouble parsing PDF files, but the latest files I need to handle are causing problems. It would appear that the parser isn't seeing false/true as a boolean and is instead seeing them as operators. Also, at first glance the code to handle arrays in CParser.cs doesn't look like it will populate the array at all. |

We'll need a sample PDF file to investigate this. |

I'll see what I can do about getting a sample PDF which doesn't contain any sensitive information. They are produced using "PCL2PDF (TM) from Visual Software" and it seems to be these sequences which are causing the problem:- q 0.12 0 0 -0.12 23.85 264.44 cm BI /W 1 /H 1 /BPC 1 /F [/AHx] /IM true ID FF> EI Q q 0.12 0 0 -0.12 84.09 264.44 cm BI /W 1 /H 1 /BPC 1 /F [/AHx] /IM true ID FF> EI Q q 0.12 0 0 -0.12 225.93 393.08 cm BI /W 1 /H 1 /BPC 1 /F [/AHx] /IM true ID FF> EI Q |
