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>

q 0.12 0 0 -0.12 84.09 264.44 cm
BI /W 1 /H 1 /BPC 1 /F [/AHx] /IM true ID
