displaying plain data without fancy features (wx)

Community matplotlib-users

Hello,

I am trying to display an array with imshow(), however I want to 'turn off'
display of axes, numbers, and all that extra stuff which comes with it. I
want only my array(grayscale image) to be shown

import wx
import matplotlib
matplotlib.use( 'WXAgg' )
from matplotlib.backends.backend_wxagg import FigureCanvasWxAgg
from matplotlib.figure import Figure

class Frame1(wx.Frame):
   def __init__(self, parent):
       wx.Frame.__init__(self,None)
       self.panel1 = wx.Panel(self)
       self.Add_MPL_Plot()

   def Add_MPL_Plot(self):
       figure = Figure(None, 80)
       canvas = FigureCanvasWxAgg(self.panel1, -1, figure)
       canvas.SetSize(wx.Size(300,300))
       subplot = figure.add_subplot(111)
       subplot.imshow(here comes my array) # i did not included it to code
for simplicity

if __name__ == '__main__':
   app = wx.PySimpleApp()
   frame = Frame1(None)
   frame.Show()

   app.MainLoop()

#########################

is there a way to do it?

another thing, is it possible to open .png images this way? (since it is
possible to save stuff plotted with imshow to .png)

Sorry for the long delay in responding.

Yes, you can call:

subplot.set_axis_off()
subplot.set_frame_on(False)

to turn all of that “stuff” off. Although, you will still have a border around it. To prevent that, then you will have to create the axes object directly and set its rect kwarg to [0, 0, 1, 1].

another thing, is it possible to open .png images this way? (since it is

Yeah, there is a imread() function:

http://matplotlib.sourceforge.net/api/pyplot_api.html?highlight=imread#matplotlib.pyplot.imread

I hope this helps!
