您可以子类化 ArtistAnimation
并覆盖 _step - 方法,例如:
You could subclass ArtistAnimation
and overwrite the _step - method, e.g.:
class SnapShotAnimation(ArtistAnimation):
def __init__(self, fig, artists, snapshot_delay, *args, **kwargs):
self._snapshot_delay = snapshot_delay
self._time_to_snapshot = snapshot_delay
ArtistAnimation.__init__(self, fig, artists, *args, **kwargs)
def _step(self, *args):
if self._time_to_snapshot <= 0:
do_snapshot()
self._time_to_snapshot = self._snap_shot_delay #reset timer
else:
self._time_to_snapshot -= self._interval
ArtistAnimation._step(*args) #ancestor method maybe better at start
def do_snapshot(self):
"""Your actual snapshot code comes here - basically saving to a output"""
fname = 'snapshot.png'
self._fig.savefig(fname)
添加:
snapshot_delay = 1000 # time in ms
改变:
ani=SnapShotAnimation(fig,result,snapshot_delay, interval=10,repeat=False)
在您的示例源中.
为了更好地了解做什么和如何做,我建议查看 matplotlib 来源.
For better understanding what and how to do, i would recommend to take a look into the matplotlib sources.
