Bug C# Foxit SDK DLL - Bitmap Distortions

[needsupport]

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).
