[Qgis-user] map composer: cannot set portrait (extend in map composer)

Thanks for the patient answer.
It does not work in my case because it assumes that the map that shall
be fitted into the item frame covers the whole QGIS main window.

But in my case I have a single tif raster file which leaves a white
space left and right to it towards the window borders.
This is not taking into account by the extends buttons.
