Question

1) A call to PInvoke function ‘PDFjet!PDFjet.NET.OptionalDeflateStream::compress’ has unbalanced the stack. This is likely because the managed PInvoke signature does not match the unmanaged target signature. Check that the calling convention and parameters of the PInvoke signature match the target unmanaged signature.

What is this? If I remove zlibwapi.dll from the same folder as the PdfJet assembly I get:
2)Unable to load DLL ‘zlibwapi.dll’: The specified module could not be found. (Exception from HRESULT: 0x8007007E) (note that I don’t add reference to this assembly, I only copy it to Debug folder, and get error1)

code:

   `static void Main(string[] args)
    {
        FileStream fos = new FileStream("Example_05.pdf", FileMode.Create);
        BufferedStream bos = new BufferedStream(fos);

        PDF pdf = new PDF(bos);
        pdf.setCompressor(Compressor.ORIGINAL_ZLIB);

        // Before you enable this flag please read README.ZLIB.TXT
        // in the 'optional' directory.

        // If PDF/A is not required use Helvetica, TimesRoman or Courier
        Font f1 = new Font(pdf, "Helvetica");
        /*
                Font f1 = new Font(pdf,
                        new FileStream(
                                "fonts/DroidFonts/DroidSans.otf", FileMode.Open),
                        CodePage.UNICODE,
                        Embed.YES);
        */
        Page page = new Page(pdf, Letter.PORTRAIT);

        TextLine text = new TextLine(f1);
        text.SetPosition(300.0, 300.0);
        for (int i = 0; i < 360; i += 15)
        {
            text.SetTextDirection(i);
            text.SetUnderline(true);
            // text.SetStrikeLine(true);
            text.SetText("             Hello, World -- " + i + " degrees.");
            text.DrawOn(page);
        }

        text = new TextLine(f1, "WAVE AWAY");
        text.SetPosition(70.0, 50.0);
        text.DrawOn(page);

        f1.SetKernPairs(true);
        text.SetPosition(70.0, 70.0);
        text.DrawOn(page);

        f1.SetKernPairs(false);
        text.SetPosition(70.0, 90.0);
        text.DrawOn(page);

        f1.SetSize(8);
        text = new TextLine(f1, "-- font.SetKernPairs(false);");
        text.SetPosition(150.0, 50.0);
        text.DrawOn(page);
        text.SetPosition(150.0, 90.0);
        text.DrawOn(page);
        text = new TextLine(f1, "-- font.SetKernPairs(true);");
        text.SetPosition(150.0, 70.0);
        text.DrawOn(page);

        Point point = new Point(300.0, 300.0);
        point.SetShape(Point.CIRCLE);
        point.SetFillShape(true);
        point.SetColor(RGB.BLUE);
        point.SetRadius(37.0);
        point.DrawOn(page);
        point.SetRadius(25.0);
        point.SetColor(RGB.WHITE);
        point.DrawOn(page);

        pdf.Flush();
        bos.Close();
    }`

Answer 1

removed pdf.setCompressor(Compressor.ORIGINAL_ZLIB); and it works
