hSection is a handle to a file mapping object that the function will use to create the DIB and can be NULL. If hSection is not NULL, it must be a handle to a file mapping object created by calling the CreateFileMapping function (otherwise CreateDIBSection will fail). Moreover, the CreateDIBSection function will locate the bitmap’s bit values at offset dwOffset in the file mapping object referred to by hSection. An application can retrieve the hSection handle by calling the GetObject function with the HBITMAP returned by CreateDIBSection.

gBrush = CreatePatternBrush(bB.GetHbitmap)

IntPtr maskHbitmap = maskImage.GetHbitmap();

void PaintLine3(IntPtr hbitmap, Point start, Point end, bool erase)

    IntPtr pOrig = SelectObject(pDC, hbitmap);

Call DeleteObject on a HBitmap object after using the GDI+ function:

public static Bitmap FromHbitmap(

    IntPtr hbitmap

FromHbitmap transfers a copy of the image bytes into returned Bitmap so it is important to call DeleteObject on the HBitmap to prevent two copies of the image from existing in the system.

Had a terrible time getting this to work to retrieve a BITMAP object from a HBITMAP, this code finally worked.

GDI32.GetObject(hBitmap, Marshal.SizeOf<GDI32.BITMAP>(), ptrToBitmap);

A better option than the above example would be to leverage Image.FromHbitmap
