如何获得Matplotlib图形大小 [英] How to get matplotlib figure size

问题描述

对于一个项目，我需要知道matplotlib图形的当前大小(以像素为单位)，但是我找不到执行该操作的方法. 有人知道该怎么做吗?

For a project, I need to know the current size (in pixels) of my matplotlib figure, but I can't find how to do this. Does anyone know how to do this ?

推荐答案

import matplotlib.plt
fig = plt.figure()
size = fig.get_size_inches()*fig.dpi # size in pixels

要针对当前图形执行此操作

To do it for the current figure,

fig = plt.gcf()
size = fig.get_size_inches()*fig.dpi # size in pixels

您可以通过以下操作获得相同的信息:

You can get the same info by doing:

bbox = fig.get_window_extent().transformed(fig.dpi_scale_trans.inverted())
width, height = bbox.width*fig.dpi, bbox.height*fig.dpi
