If 'figure', uses the figure's dpi value. Use a non-default backend to render the file, e.g. TkAgg, saving: (960, 1280, 4) in all cases. Amount of padding around the figure when bbox_inches is 'tight'. Les tracés matplotlib savefig() diffèrent de show() (3) ... fig.savefig('temp.png', dpi=fig.dpi, bbox_inches='tight') #or: fig.savefig('temp.png', dpi=fig.dpi, bbox_inches='tight', pad_inches=0.5) La première option minimise juste la mise en page et les bordures et la deuxième option permet d'ajuster manuellement les bordures un peu. Some styles failed to load. Currently only supported by the postscript backend. Sauf si vous avez des images bitmap dans il y, le DPI est plutôt vide de sens dans un vecteur d'image, car ils sont indépendants de la résolution. Nous pouvons spécifier le chemin et le format dans savefig() dans lequel le tracé doit être enregistré. If None, defaults to rcparam['savefig.dpi'] codec: str, optional. and defaults depend on the image format and backend: Additional keyword arguments that are passed to possibly some backend-dependent object such as © Copyright 2002 - 2012 John Hunter, Darren Dale, Eric Firing, Michael Droettboom and the Matplotlib development team; 2012 - 2018 The Matplotlib development team.
