Dear Ben:
I am working on a Image editing program. That is why I have to access
the bits data directly.
"bitmap[(long)i]" does not work. It just crashed.
My code is like this:
UInt32 i, len;
len=640;
len*=480;
pBitmap=BmpCreate(640,480,16,NULL, &err);
bufPart=(UInt16*)BmpGetBits(pBitmap);
for (i=0;i<len;i++)
{
bufPart[i]=0x07e0;
}
It will crash while i>65535.
