I use DirectDraw for reason of compatibility with Windows NT.
the problem is:
when I post one image which is in the hidden surface on the primary surface in a smaller frame the quality of image is losed.
The code that I use is:
m_pDDPrimarysurface->Blt(&m_rect, m_pDDStoreSurface, NULL, DDBLT_WAIT, NULL);
if you have a solution of my problem or you have a advice,help me please,it's very urgent.
thank you in advance.
