recognize Number from Picture

[DavinE]

Hello Guys,

i have en other Idee for my app to do some inputs easier.
My Picture look's like this:
https://imgur.com/a/QKuykE7

is it possible to read the Number on it ?
7989476the beginning ! is not on every Number..

Maybe anyone know's whether it's possible to do this.

Thanks guys!

@DavinE weird because I have the same answer with both modes if, an only if, I restart entirely Pythonista, and I have been obliged to add to your code...

from   functools import partial

Have you ever used my complete code above?
maybe there is a mistake?

@DavinE I used your code you just posted. And it does not include the from functools import partial, thus I have some doubts....how do you remove Pythonista from memory?

@DavinE I have reinstalled this last code, restarted Pythonista, run and result is

orderConfirmation -- [['some text', '1179629', '+1', '74.20', 92.75, '0001', ''], ['some text', '3500670', '+1', '74.50', 93.12, '0001', ''], ['some text', '3500156', '+1', '32.44', 40.55, '0001', ''], ['some text', '3532239', '+1', '55.10', 68.88, '0001', ''], ['some text', '1177739', '+1', '0.84', 1.05, '0001', '']]

And you did swipe up Pythonista little window?

Yes, i did ^^

[cvp]

@DavinE I had downloaded your image in my photos and Thus I use the photos mode. And you?

[DavinE]

@cvp, the same as you 😊

[cvp]

@DavinE Nothing special in your pythonista_startup in site-packages?

[DavinE]

@cvp, i look only Stash

[cvp]

@DavinE Could you power off/on your device to be sure Pythonista memory is cleared (I agree that it is not very professional but who knows)

[cvp]

@DavinE do you have two versions of your program?

[DavinE]

Yes, i try that but it changed nothing

[DavinE]

@cvp said:

How do you mean that ?

[cvp]

@DavinE because you made tests with edited and original mode, perhaps you have two versions of your program.
Anyway, could you download the photo from Imgur in your photos only to be sure we work with same material

this one

[DavinE]

@cvp,

Lol, I'm using the same picture!
but when I use the picture I load from imgur and the "original" doesn't ...
what's going on.... 🙈

[cvp]

@DavinE that is because the photo you have in your Photos has internally two objects, the original and the edited. BuT the photo in Imgur has only one internal object. Compare their size

and the "original" doesn't ...

Does not what?
