Images saved as SVG get upside down when svg.image_noscale is True.

[tkanmae]

I created a figure with an image using imshow() and saved it as SVG. I realized that the saved image gets upside down when svg.image_noscale is True.

I'm using matplotlib == 1.2.0 on Mac OS X.

The following code reproduces the issue.

import matplotlib.pyplot as plt
import numpy as np

# Use default configuration.
plt.matplotlib.rcdefaults()

# Create a figure.
fig = plt.figure()
ax = fig.add_subplot(111)
X, Y = np.meshgrid(np.arange(-5, 5, 1), np.arange(-5, 5, 1))
Z = np.sin(Y**2)
ax.imshow(Z, cmap='gray')

# These are ok.
fig.savefig('ok.png')
fig.savefig('ok.svg')

# Set `svg.image_noscale` to True.
plt.rcParams['svg.image_noscale'] = True
# Then, the image is upside down.
fig.savefig('bad.svg')

Thanks,

Thanks. I can confirm this on current master, too.

I did not have the issue when I was using 1.1.1.

I have proposed a solution in #1674. Would you be able to try it out and see if it works for you?

Resolved in #1674.
