void CBRUSHTESTDlg::OnPaint()
{
CPaintDC dc(this);
CBitmap bmp;
bmp.LoadBitmap(IDB_BITMAP1);
BITMAP bitmap;
int size = bmp.GetBitmap(&bitmap);
CDC memDC;
memDC.CreateCompatibleDC(&dc);
memDC.SelectObject(&bmp);
dc.BitBlt(10, 10, bitmap.bmWidth, bitmap.bmHeight, &memDC, 0, 0, SRCCOPY); //向窗口中绘制位图
}
（2）使用StretchBlt
void CBRUSHTESTDlg::OnPaint()
{
CPaintDC dc(this);
CBitmap bmp;
bmp.LoadBitmap(IDB_BITMAP1);
BITMAP bitmap;
int size = bmp.GetBitmap(&bitmap);
CDC memDC;
memDC.CreateCompatibleDC(&dc);
memDC.SelectObject(&bmp);
dc.SetStretchBltMode(STRETCH_HALFTONE);
dc.StretchBlt(0, 0, bitmap.bmWidth, bitmap.bmHeight, &memDC, 0, 0, bitmap.bmWidth, bitmap.bmHeight, SRCCOPY); //向窗口中绘制位图
}
