[Qgis-developer] Composer map size and extent

[Marco Hugentobler]

Hi Alexander

Afaik if you set the new extent such that the width/height ration of the 
extent is the same as the item's one, it won't change size.
Another possibility is to set the new extent and call setSceneRect() 
just after that.

For the scale: QgsComposerMap::setNewScale should not change the item 
widht/height.

Regards,
Marco
