How to save figures to pdf as raster images in Matplotlib?
To save figures to pdf as raster images in Matplotlib, we can take the following steps −
- Set the figure size and adjust the padding between and around the subplots.
- Create a new figure or activate an existing figure.
- Add an axes to the figure as part of a subplot arrangement.
- Create random data using numpy.
- Display the data as an image, i.e., on a 2D regular raster.
- Save the plot as pdf format.
Example
import numpy as np import matplotlib.pyplot as plt plt.rcParams["figure.figsize"] = [7.50, 3.50] plt.rcParams["figure.autolayout"] = True fig = plt.figure() ax = fig.add_subplot(111, rasterized=True) data = np.random.rand(5, 5) ax.imshow(data, cmap="copper", aspect=True, interpolation="nearest") plt.savefig("rasterized.pdf")
Output
When we execute the code, it will save the following plot in the project directory with the name "rasterized.pdf".
