What do you expect when the extent of an object has not the same aspect ratio as the map frame's one ?
The current behaviour is to resize the height of the frame, keeping the width.
Other choices are :
- resize the extent in the height direction (that what the composer "Set to map canvas" seems to do).
- resize the content (not sure it is wanted)

Perhaps we should expose this choice to the user ...

Hi, I think everybody expects centered images on both axes when using Atlas. And the bug described here in not only a problem of centering. Data is missing in the lower part of the image. This shouldn't be.

Data are not exactly missing. If you change settings in order to display the frame border, you will see the frame resized in height to fit the object's extent.
But I understand and agree: keeping the frame's border untouched and centering the object is the key.
