Numpy Matrix to tkinter Canvas
Here is working solution, slightly modified to make it work (some function was deprecated) and to simplify it to keep only the necessary part. We have to use Image.frombytes(...) to read the data in the numpy matrix.
import Tkinterfrom PIL import Image, ImageTkimport numpyclass mainWindow(): def __init__(self): self.root = Tkinter.Tk() self.frame = Tkinter.Frame(self.root, width=500, height=400) self.frame.pack() self.canvas = Tkinter.Canvas(self.frame, width=500,height=400) self.canvas.place(x=-2,y=-2) data=numpy.array(numpy.random.random((400,500))*100,dtype=int) self.im=Image.frombytes('L', (data.shape[1],data.shape[0]), data.astype('b').tostring()) self.photo = ImageTk.PhotoImage(image=self.im) self.canvas.create_image(0,0,image=self.photo,anchor=Tkinter.NW) self.root.update() self.root.mainloop()mainWindow()
