I found this in the MSDN
"biHeight

    The height of the bitmap, in pixels. If biHeight is positive, the bitmap is
a bottom-up DIB and its origin is the lower-left corner. If biHeight is
negative, the bitmap is a top-down DIB and its origin is the upper-left corner.

    If biHeight is negative, indicating a top-down DIB, biCompression must be
either BI_RGB or BI_BITFIELDS. Top-down DIBs cannot be compressed.

    If biCompression is BI_JPEG or BI_PNG, the biHeight member specifies the
height of the decompressed JPEG or PNG image file, respectively."

Is the function CreateDIBImage acting correctly when the bitmap has a negative
height? Is that implemented?
