How to open an image in Python - image

I am new to python. I am learning how to add images to my Tkinter file. However, when I try to run the following code, the interpreter returns the error: FileNotFoundError: [Errno 2] No such file or directory: lee.jpg
I hypothesize that I need a more specific path and have already ensured that both the file and image are in the same folder. Any explanations would be appreciated.
from tkinter import *
from PIL import ImageTk, Image
#Main Window
window = Tk()
window.title("Join")
window.geometry("800x600")
window.configure(background='white')
path = "lee.jpg" # I believe this is causing issues
#Makes image Tkinter-compatible
img = ImageTk.PhotoImage(Image.open(path))
panel = Label(window, image=img)
panel.pack(side="bottom", fill="both", expand="yes")
#Start
window.mainloop()

This is actually pretty simple and can be achieved with the below:
from tkinter import * #imports tkinter
root = Tk() #establishes root as the Tk window
image = PhotoImage(file="lee.jpg") #imports image from file
label = Label(root, image=image) #creates a Label object containing the image
label.pack() #packs the Label into the Tk window
root.mainloop() #starts event loop
This is probably the simplest way to achieve the desired result.
If you're new to Python I would suggest a free tutorial rather than Stack Overflow, and if you're new to tKinter then http://effbot.org/tkinterbook is your friend.

you can use pillow module
from PIL import Image
img = Image.open(r'path/to/file.png')
img.show()
i hope this helps....

how to convert python code into executable file

I have a python code that run perfect now i want to convert this code into an executable file .I am using python 3.6.
Until now I was able to convert it ,and make it run but the problem is that when the user try to run the .exe file cmd window is opened.
how can I make the cmd window to be hidden OR to not show?
the code below is to create the build folder that includes the converted executable file.
setup.py
import cx_Freeze
import sys
import os
import matplotlib
#os.environ['TCL_LIBRARY'] = "C:\\LOCAL_TO_PYTHON\\Python35-32\\tcl\\tcl8.6"
#os.environ['TK_LIBRARY'] = "C:\\LOCAL_TO_PYTHON\\Python35-32\\tcl\\tk8.6"
os.environ['TCL_LIBRARY'] = "C:\\EXECUTABLE_PROGRAMS\\Python3.6\\tcl\\tcl8.6"
os.environ['TK_LIBRARY'] = "C:\\EXECUTABLE_PROGRAMS\\Python3.6\\tcl\\tk8.6"
base = None
if sys.platform == 'win32':
base='Win32GUI'
executables = [cx_Freeze.Executable("myPDFviewer.py",base=None)]
cx_Freeze.setup(
name = "this is a test",
options = {"build_exe": {"packages":["numpy"],}},
version = "0.01",
descriptions = "Trying to get this to work",
executables = executables
)
Change base=None to base="Win32GUI"

Cannot open Matplotlib figure in new Process on Mac

If I try to launch a process that creates a matplotlib figure, the process hangs when trying to create the figure. Here is some code that reproduces the problem:
from matplotlib import pyplot as plt
from multiprocessing import Process
import numpy as np
def plotit():
data = np.cos(np.linspace(0, 10, 100))
print 'Gets Here'
plt.figure()
print 'But This is never printed.'
plt.plot(data)
plt.show()
def main():
p = Process(target=plotit)
p.start()
print raw_input('Press Enter when Done>>')
if __name__ == '__main__':
main()
The output from this is:
Press Enter when Done>>Gets Here
So it seems to freeze on plt.figure().
Note: The code seems to run fine on linux - it just fails on Mac! (My matplotlib backend is TkAgg in both cases). (Python 2.7.12, matplotlib 2.0.2., OSX Sierra 10.12)
Is there any way around this?

Tkinter GUI Not Opening in Pydev (Liclipse)

When I am trying to run my program based off a sample Tkinter GUI, nothing happens. I am still new to Pydev, but I find this rather unusual. I have a Main.py file containing the code, and I try to simply run the module without any success.
I simply copy/pasted from this reference,
# Main.py
import tkinter as tk;
class Application(tk.Frame):
def __init__(self, master=None):
super().__init__(master)
self.pack()
self.create_widgets()
def create_widgets(self):
self.hi_there = tk.Button(self)
self.hi_there["text"] = "Hello World\n(click me)"
self.hi_there["command"] = self.say_hi
self.hi_there.pack(side="top")
self.quit = tk.Button(self, text="QUIT", fg="red",
command=root.destroy)
self.quit.pack(side="bottom")
def say_hi(self):
print("hi there, everyone!")
root = tk.Tk()
app = Application(master=root)
app.mainloop()
The only result of running the module is an empty Liclipse console dedicated to Main.py.
I have also tried other examples from other sites with no luck. Also, I am currently on MacOS if it matters.
Are you sure you have everything properly (working directory, python path...) configured in Liclipse? I have just tried in a fresh install and, after configuring Liclipse to run the current project in Python 3.6 and after selecting the main project file as being this source code, it runs and shows a window with a button, as intended, and it also prints the text to console.
Also, it does not feel very "pythonic" to initialize a button that way. I would rather suggest like this:
# Main.py
import tkinter as tk;
class Application(tk.Frame):
def __init__(self, master=None):
super().__init__(master)
self.pack()
self.create_widgets()
def create_widgets(self):
mytext = "Hello World\n(click me)"
self.hi_there = tk.Button(self, text=mytext, command=self.say_hi)
self.hi_there.pack(side="top")
self.quit = tk.Button(self, text="QUIT", fg="red", command=root.destroy)
self.quit.pack(side="bottom")
def say_hi(self):
print("hi there, everyone!")
root = tk.Tk()
app = Application(master=root)
app.mainloop()
The code looks a little more readable and works in the same way. When you start growing your interface, it will be many lines long and by reducing two lines at each button, you can make it a lot shorter. I have been coding a tkinter app with more that 1500 lines of code and at that point I promised myself that I would try to learn how to keep it more organized and short ;)

Win32com Save PDF to XML with Acrobat Pro X > com_error "-2147467263, 'Not implemented'" [duplicate]

This question already has answers here:
"Not implemented" Exception when using pywin32 to control Adobe Acrobat
(2 answers)
Closed 6 years ago.
Python 2.7 (r27:82525, Jul 4 2010, 09:01:59) [MSC v.1500 32 bit (Intel)] on win32

Adobe Acrobat X 10.0.0
I want to use Python to automate Acrobat Pro to export a PDF to XML. I already tried it manually using the 'Save As' dialog box from the running program and now want to do it via a Python script. I have read many pages including parts of the Adobe SDK, SDK Forum, VB Forums and am having no luck.
I read Blish's problem here: "Not implemented" Exception when using pywin32 to control Adobe Acrobat
And this page: timgolden python/win32_how_do_i/generate-a-static-com-proxy.html
I am missing something. My code is:
import win32com.client
import win32com.client.makepy
win32com.client.makepy.GenerateFromTypeLibSpec('Acrobat')
adobe = win32com.client.DispatchEx('AcroExch.App')
avDoc = win32com.client.DispatchEx('AcroExch.AVDoc')
avDoc.Open('C:\Documents and Settings\PC\Desktop\a_PDF.pdf', 'C:\Documents and Settings\PC\Desktop')
pdDoc = avDoc.GetPDDoc()
jObject = pdDoc.GetJSObject()
jObject.SaveAs('C:\Documents and Settings\PC\Desktop\a_PDF.xml', "com.adobe.acrobat.xml-1-00")
The full error is:
Traceback (most recent call last):
File "<pyshell#31>", line 1, in <module>
jObject.SaveAs('C:\Documents and Settings\PC\Desktop\a_PDF.xml', "com.adobe.acrobat.xml-1-00")
File "C:\Python27\lib\site-packages\win32com\client\dynamic.py", line 511, in __getattr__
ret = self._oleobj_.Invoke(retEntry.dispid,0,invoke_type,1)
com_error: (-2147467263, 'Not implemented', None, None)
I'm guessing it has to do with make.py but I don't understand how to implement it in my code.
I pulled this line from my code and got the same error when I ran it:
win32com.client.makepy.GenerateFromTypeLibSpec('Acrobat')
I then changed these two lines from 'DispatchEX' to 'Dispatch' and same error:
adobe = win32com.client.Dispatch('AcroExch.App')
avDoc = win32com.client.Dispatch('AcroExch.AVDoc')
When I run the Dispatches by themselves and then call them back I get:
>>> adobe = win32com.client.DispatchEx('AcroExch.App')
>>> adobe
<win32com.gen_py.Adobe Acrobat 10.0 Type Library.CAcroApp instance at 0x18787784>
>>> avDoc = win32com.client.Dispatch('AcroExch.AVDoc')
>>> avDoc
<win32com.gen_py.Adobe Acrobat 10.0 Type Library.CAcroAVDoc instance at 0x20365224>
Does this mean I should make only one call to Dispatch? I pulled:
adobe = win32com.client.Dispatch('AcroExch.App')
and got the same error.
This Adobe site says:
AVDoc
Product availability: Acrobat, Reader
Platform availability: Macintosh, Windows, UNIX
Syntax
typedef struct _t_AVDoc* AVDoc;
A view of a PDF document in a window. There is one AVDoc per displayed document. Unlike a PDDoc, an AVDoc has a window associated with it.
acrobat_sdk/9.1/Acrobat9_1_HTMLHelp/API_References/Acrobat_API_Reference/AV_Layer/AVDoc.html#AVDocSaveParams
The PDDoc page says:
A PDDoc object represents a PDF document. There is a correspondence between a PDDoc and an ASFile. Also, every AVDoc has an associated PDDoc, although a PDDoc may not be associated with an AVDoc.
/9.1/Acrobat9_1_HTMLHelp/API_References/Acrobat_API_Reference/PD_Layer/PDDoc.html
I tried the following code and also got the same error:
import win32com.client
import win32com.client.makepy
pdDoc = win32com.client.Dispatch('AcroExch.PDDoc')
pdDoc.Open('C:\Documents and Settings\PC\Desktop\a_PDF.pdf')
jObject = pdDoc.GetJSObject()
jObject.SaveAs('C:\Documents and Settings\PC\Desktop\a_PDF.xml', "com.adobe.acrobat.xml-1-00")
Same error if I change:
pdDoc = win32com.client.Dispatch('AcroExch.PDDoc')
to
pdDoc = win32com.client.gencache.EnsureDispatch('AcroExch.PDDoc')
like here: win32com.client.Dispatch works but not win32com.client.gencache.EnsureDispatch
user2993272, you were almost there: just one more line and the code you have should have worked flawlessly.
I'm going to attempt to answer in the same spirit as your question and provide you as much details as I can.
This thread holds the key to the solution you are looking for: https://mail.python.org/pipermail/python-win32/2002-March/000260.html
I admit that the post is not the easiest to find (perhaps Google scores it low based on the age of the content?).
Specifically, applying this piece of advice will get things running for you: https://mail.python.org/pipermail/python-win32/2002-March/000265.html
For completeness, this piece of code should get the job done and not require you to manually patch dynamic.py (snippet should run pretty much out of the box):
# gets all files under ROOT_INPUT_PATH with FILE_EXTENSION and tries to extract text from them into ROOT_OUTPUT_PATH with same filename as the input file but with INPUT_FILE_EXTENSION replaced by OUTPUT_FILE_EXTENSION

def acrobat_extract_text(f_path, f_path_out, f_basename, f_ext):
avDoc = Dispatch("AcroExch.AVDoc") # Connect to Adobe Acrobat
# Open the input file (as a pdf)
ret = avDoc.Open(f_path, f_path)
assert(ret) # FIXME: Documentation says "-1 if the file was opened successfully, 0 otherwise", but this is a bool in practise?
pdDoc = avDoc.GetPDDoc()
dst = os.path.join(f_path_out, ''.join((f_basename, f_ext)))
# Adobe documentation says "For that reason, you must rely on the documentation to know what functionality is available through the JSObject interface. For details, see the JavaScript for Acrobat API Reference"
jsObject = pdDoc.GetJSObject()
# Here you can save as many other types by using, for instance: "com.adobe.acrobat.xml"
jsObject.SaveAs(dst, "com.adobe.acrobat.accesstext")
pdDoc.Close()
avDoc.Close(True) # We want this to close Acrobat, as otherwise Acrobat is going to refuse processing any further files after a certain threshold of open files are reached (for example 50 PDFs)
del pdDoc

I have tested this on WinPython x64 2.7.6.3, Acrobat X Pro

Inserting Image using Class in Python 3.3.1

I am trying to insert an image(logo) in GIUs to display it in top left corner using grid and preferable in frame.
When I do this code without demonstrator then it works perfectly but as soon I put it in Demonstrator the image disappears. Any Suggestion?
class TaskGUI():
def __init__(self,master):
header = Frame(master, )
header.grid(row=2,column=1,sticky=W)
canvas= Canvas(header, bg= 'pink')
Label(header, bg= 'blue' ).grid(row=1)
canvas.grid(row=1,column=1)
imgLogo = PhotoImage(file = 'logo.gif' )
canvas.create_image(10,10, image= imgLogo, ancho= NW)
if __name__ == "__main__":
top =Tk()
top.geometry('10920x1080')
top.title("Stel")
top.grid()
app = TaskGUI(top)
top.mainloop()
I tried to use PIL libary but could not find any solution on this on either, I get this error:
from PIL import Image,ImageTk
File "C:\Program Files\Python\PIL\Image.py", line 57
except ImportError, v:
^
SyntaxError: invalid syntax
You are trying to run the code using Python 3 but PIL is only compatible with Python 2.
In Python 3 the syntax to catch an exception is except ImportError as v while it used to be except ImportError, v in Python 2. Note that changing this most likely won't help since there will be many other incompatible things within PIL.
However, Pillow is a compatible fork of PIL that is compatible with Python 3.
