Answer 1

Here is the starting point of extracting the different commands of a page:

    var file = "test.pdf";
    var reader = new PdfReader(file);

    var streamBytes = reader.GetPageContent(2);
    var tokenizer = new PRTokeniser(new RandomAccessFileOrArray(streamBytes));
    var ps = new PdfContentParser(tokenizer);

    List operands = new List();
    while (ps.Parse(operands).Count > 0)
    {
        PdfLiteral oper = (PdfLiteral)operands[operands.Count - 1];
        var cmd = oper.ToString();

        switch (cmd)
        {
            case "q":
                Console.WriteLine("SaveGraphicsState(); //q");
                break;

            case "Q":
                Console.WriteLine("RestoreGraphicsState(); //Q");
                break;

           // good luck with the rest!

        }
    }
