Hello,
I am writing a GUI using GTK+ library. I have a question about axes class
imshow method memory consumption. If I pass the imshow an array, the resulting
memory consuption is approximatelly 40 times greater than the array size. If I
do not add the canvas to a window (in a code below), the memory consuption is
as expected. Any tips on how to reduce the memory consuption would be very
appreciated. Configuration and script are below.
os: Windowx XP
matplotlib version: 0.99.1
downloaded from: sourceforge.net
script:
from matplotlib.figure import Figure
from matplotlib.backends.backend_gtkagg import FigureCanvasGTKAgg
from pylab import rand
import gtk
window = gtk.Window()
window.connect("destroy", gtk.main_quit)
figure = Figure(figsize=(8,6), dpi=72)
canvas = FigureCanvasGTKAgg(figure)
axes = figure.add_subplot(111)
window.add(canvas)
axes.imshow(rand(1024,1024))
canvas.draw()
window.show_all()
gtk.main()
