How to save an image as a variable?

Question

Now, I have a python game that has sprites, and it obtains the images from files in its directory. I want to make it such that I do not even need the files. Somehow, to pre-store the image in a variable so that i can call it from within the program, without the help of the additional .gif files

The actual way i am using the image is

image = PIL.Image.open('image.gif')

So it would be helpful if you could be precise about how to replace this code

Solution 1

Continuing @eatmeimadanish's thoughts, you can do it manually:

import base64

with open('image.gif', 'rb') as imagefile:
    base64string = base64.b64encode(imagefile.read()).decode('ascii')

print(base64string)  # print base64string to console
# Will look something like:
# iVBORw0KGgoAAAANS  ...  qQMAAAAASUVORK5CYII=

# or save it to a file
with open('testfile.txt', 'w') as outputfile:
    outputfile.write(base64string)


# Then make a simple test program:

from tkinter import *
root = Tk()

# Paste the ascii representation into the program
photo = 'iVBORw0KGgoAAAANS ... qQMAAAAASUVORK5CYII='

img = PhotoImage(data=photo)
label = Label(root, image=img).pack()

This is with tkinter PhotoImage though, but I'm sure you can figure out how to make it work with PIL.

Solution 2

Here is how you can open it using PIL. You need a bytes representation of it, then PIL can open a file like object of it.

import base64
from PIL import Image
import io

with open("picture.png", "rb") as file:
    img = base64.b64encode(file.read())

img = Image.open(io.BytesIO(img))
img.show()

Doesn't tkinter has an image object? Qt has one, named QImage.

but you have to open the image each time from the file

[Aran-Fey]

Why? Why do you think it's a good idea to embed images in code?

[roganjosh]

And when the program ends, what happens to the image data?

i want to convert the .py into .exe, and i want everything to bo neat. And i only want to carry one file around

[ѕняєє ѕιиgнι]

@rojanghosh The data should still be there so that i can access it again next time i run the code

[Aran-Fey]

"How do I package my program into an exe" is a much better question than "how do I put images into python scripts". And the answer definitely won't be "Put all the data in your python script".

I know how to convert it into an executable, but I did not know how to save the image in the code, so that the executable can handle it

@Aran-Fey: I think you're being a bit harsh. I think it's perfectly reasonable to embed some image data in a script under some circumstances. It may not be a best practice, but it's still a reasonable solution.

@BryanOakley Hmm, I think I can see what you mean. But that really wasn't intentional. I smelled an XY problem, so I asked a question to find out if I was right, and then I simply stated that it would've been better to ask about the X rather than the Y. I can see why you would think that I was... hmmm... cold, but it's really all factual and neutral.

What would the value of img be an alias for?

Could you please specify how to implement this in PIL, I am having difficulties

[figbeam]

I don't use PIL an haven't installed it, so I can not give you advice on this other than to suggest you look at: How to convert base64 string to a PIL Image object.

Where's your explanation?

We got there at the end.
