I demand it to beryllium grayscale due to the fact that I privation to gully connected apical of the representation with colour.
I publication successful the representation and person to grayscale utilizing PIL’s Representation.unfastened().person("L")
representation = Representation.unfastened(record).person("L")
Past I person the representation to a matrix truthful that I tin easy bash any representation processing utilizing
matrix = scipy.misc.fromimage(representation, zero)
Nevertheless, once I bash
fig() matplotlib.pyplot.imshow(matrix) entertainment()
it shows the representation utilizing a colormap (i.e. it’s not grayscale).
What americium I doing incorrect present?
The pursuing codification volition burden an representation from a record representation.png and volition show it arsenic grayscale.
import numpy arsenic np import matplotlib.pyplot arsenic plt from PIL import Representation fname = 'representation.png' representation = Representation.unfastened(fname).person("L") arr = np.asarray(representation) plt.imshow(arr, cmap='grey', vmin=zero, vmax=255) plt.entertainment()
If you privation to show the inverse grayscale, control the cmap to cmap='gray_r'.
