for (int i=0; i<newHeight; ++i)
{
for (int j=0; j<newWidth; ++j)
{
long lVal=0;
memcpy(&lVal, &buf[nCount], 4);
// Get the reverse order


int b = GetRValue(lVal);
int g = GetGValue(lVal);
int r = GetBValue(lVal);


lVal = RGB(b, g, r);
memcpy(&newbuf[newCount], &lVal, 4);


newCount+=4;
nCount +=8;
}
}


Thanks in advance
