  • Bug C# Foxit SDK DLL - Bitmap Distortions

    Hi

    I'm trying to implement PDF View functionality of Foxit PDF SDK DLL within WPF application
    Here some parts of code

    #region Code starts here
    bool IsInit = false;
    private void InitBitmap(string file)
    {
    if (!IsInit)
    {
    FPDFView.FPDF_InitLibrary(System.Diagnostics.Proce ss.GetCurrentProcess().Handle);
    FPDFView.FPDF_UnlockDLL("SDKRDTEMP", "7E92543CBE6996B4F284AE93F4F9FF964280E536");
    IsInit = true;
    }

    var pdfDoc = FPDFView.FPDF_LoadDocument(file, String.Empty);
    if (pdfDoc == null)
    return;

    var pdfPage = FPDFView.FPDF_LoadPage(pdfDoc, 0);
    if (pdfPage == null)
    return;

    Double pdfWidth = FPDFView.FPDF_GetPageWidth(pdfPage);
    Double pdfHeight = FPDFView.FPDF_GetPageHeight(pdfPage);

    int sizeX = (int)pdfWidth;
    int sizeY = (int)pdfHeight;
    Bitmap bitmap = null;

    WindowInteropHelper wih = new WindowInteropHelper(this);
    using (var gr = Graphics.FromHwnd(wih.Handle))
    {
    var hdc = gr.GetHdc();
    sizeX = (int)pdfWidth / 72 * MyWinApi.GetDeviceCaps(hdc, MyWinApi.DeviceCap.LOGPIXELSX);
    sizeY = (int)pdfHeight / 72 * MyWinApi.GetDeviceCaps(hdc, MyWinApi.DeviceCap.LOGPIXELSY);
    gr.ReleaseHdc(hdc);
    }

    bitmap = new Bitmap(sizeX, sizeY);
    using (var gr = Graphics.FromImage(bitmap))
    {
    var hdc = gr.GetHdc();
    FPDFView.FPDF_RenderPage(hdc, pdfPage, 0, 0, sizeX, sizeY, 0, 0 | 1 | 2);
    gr.ReleaseHdc(hdc);
    }

    var bmpSource = System.Windows.Interop.Imaging.CreateBitmapSourceF romHBitmap(
    bitmap.GetHbitmap(),
    IntPtr.Zero,
    Int32Rect.Empty,
    BitmapSizeOptions.FromWidthAndHeight(sizeX, sizeY)
    //BitmapSizeOptions.FromEmptyOptions()
    );
    img.BeginInit();
    img.Source = bmpSource;
    img.EndInit();
    }
    #endregion Code ends here

    And what I have as output is distorted bitmap. So my question is WHY?

    Seems all the thing was in DIB (device independent bitmap).
