Sometimes, we want to specify and save a figure with exact size in pixels with Python Matplotlib.
In this article, we’ll look at how to specify and save a figure with exact size in pixels with Python Matplotlib.
How to specify and save a figure with exact size in pixels with Python Matplotlib?
To specify and save a figure with exact size in pixels with Python Matplotlib, we set the figsize and dpi when calling figure.
For instance, we write
plt.figure(figsize=(800 / my_dpi, 800 / my_dpi), dpi=my_dpi)
to call figure with the figsize calculated by the width and height in pixels divided by my_dpi.
And we set dpi to my_dpi to set the dpi.
This will set the size to the width and height we want in pixels.
Conclusion
To specify and save a figure with exact size in pixels with Python Matplotlib, we set the figsize and dpi when calling figure.
