Hi, I've found a bug in imread which causes images in PNG and JPEG format to be flipped when using imshow. For example,
import matplotlib matplotlib.use('Agg') import matplotlib.pyplot as plt fig = plt.figure() ax = fig.add_subplot(1,2,1) image = plt.imread('2mass_rgb.png') ax.imshow(image, origin='upper', extent=[0.5,723.5,0.5,724.5]) ax = fig.add_subplot(1,2,2) image = plt.imread('2mass_rgb.jpg') ax.imshow(image, origin='upper', extent=[0.5,723.5,0.5,724.5]) fig.savefig('rgb.png') The input and output files can be found at https://www.dropbox.com/s/96npxuglpkd7y1u I have submitted a bug report at https://github.com/matplotlib/matplotlib/issues/101 Thanks for any help, Cheers, Tom ------------------------------------------------------------------------------ WhatsUp Gold - Download Free Network Management Software The most intuitive, comprehensive, and cost-effective network management toolset available today.
