Hi Paolo,

raster image storing overview is indeed located in
QgsMapOverviewCanvas class, member mPixmap. But it's protected and
there's no getter function to obtain it. Other issue is how to access
QgsMapOverviewCanvas - it's not possible get pointer to it from
QgsMapCanvas. In case of enough interest, these geter functions could
be added.

But can you explain me your use case of overview pixmap?
