Solved
Thanks all of you for your ideas and suggestions
I finally realized the serialize(archive& ar, const unsigned) funktion using
ar & make_nvp("data", make_binary_object(mpData, mWidth*mHeight);
but I have to say that the memory behind mpData bust be allocated
first on reading an image.
Finaly I endet up with
template<class archive>
void serialize(archive& ar, const unsigned int version) {
using boost::serialization::make_nvp;
using boost::serialization::make_binary_object;
if (archive::is_saving::value) {
ar & make_nvp("width", mWidth);
ar & make_nvp("height", mHeight);
} else if (archive::is_loading::value)
int w, h;{
ar & make_nvp("width", w);
ar & make_nvp("height", h);
if ((w != mWidth) || (h != mHeight) {
w = mWidth; h = mHeight;
if(mpData != NULL) delete mpData;
mpData = new char[w*h];
}
ar & make_nvp("data", make_binary_object(mpData, mWidth*mHeight);
}
Thanks again

also you could try
ar & make_nvp("data", binary_object(sizeof(mpData), & mpData))
This code do not work for dynamic allocation of mpData. data_type * mpData = new data_type[MAX]; sizeof(mpData) = sizeof(data_type *);
but it will be fine if you have static allocation : data_type mpData[MAX]; sizeof(mpData) = MAX * sizeof(data_type);
