Serial CBitmap

How would you do this?
I thought something like this would work but it doesn due to operator<< not being defined or something.

Code:

---

class SerialBitmap : public CBitmap {
    DECLARE_SERIAL(SerialBitmap)
public:

    virtual void Serialize(CArchive& ar);
};

---

Code:

---


IMPLEMENT_SERIAL(SerialBitmap, CBitmap, 3);

void SerialBitmap::Serialize(CArchive& ar)
{
    BITMAP bmp;

    if (ar.IsStoring()) {       
        GetBitmap(&bmp);
        ar << bmp.bmType;
        ar << bmp.bmWidth;
        ar << bmp.bmHeight;
        ar << bmp.bmWidthBytes;
        ar << bmp.bmPlanes;
        ar << bmp.bmBitsPixel;
       
        BYTE* bits = (BYTE*)bmp.bmBits;
        for (int i = 0; i < bmp.bmHeight; ++i) {
            for (int j = 0; j < bmp.bmWidthBytes; ++j) {
                ar << *bits;
                bits++;
            }
        }
    } else {       
        ar >> bmp.bmType;
        ar >> bmp.bmWidth;
        ar >> bmp.bmHeight;
        ar >> bmp.bmWidthBytes;
        ar >> bmp.bmPlanes;
        ar >> bmp.bmBitsPixel;

        bmp.bmBits = malloc(bmp.bmHeight * bmp.bmWidthBytes);
        BYTE* bits = (BYTE*)bmp.bmBits;
        for (int i = 0; i < bmp.bmHeight; ++i) {
            for (int j = 0; j < bmp.bmWidthBytes; ++j) {
                ar >> *bits;
                bits++;
            }
        }

       
        SetBitmapBits(bmp.bmHeight * bmp.bmWidthBytes, (const void*)bits);
        SetBitmapDimension(bmp.bmWidth, bmp.bmHeight);
    }
}

Never mind. Found out that CBitmap does serialize.
