[Matplotlib-users] plotting large images

[Štěpán T. <ste...@se...>]

Hi,




I would like to plot multiple overlayed 4096x4096 images in one axes. If I 
run this code the plot takes 300 MB of memory:




import numpy as np

import matplotlib.pyplot as plt




if __name__ == '__main__':

    img = np.zeros((4096, 4096))

    img[100: 300, 100:1500] = 200

    imgplot = plt.imshow(img)




    plt.show()




And it takes additional 300 MB for every image with this size added into 
plot. Is there any way to reduce memory consumption without need of data 
resampling?




My configuration:

Matplotlib 1.2.1

Numpy 1.7.1

Ubuntu 13.04 64 bit




Best
