cImage | A simple image processing library for Python educators | Computer Vision library

Is your main process a running application or something that executes and finishes? Especially since you say you are just trying to print some text. The main process in any container needs to be a running process, otherwise if the main process ends or exits then docker feels the container understands that as the application has failed and restarts it, hence it can go into a loop of restarting again and again.

You can may be use an application that is running on a port:

First I will answer the question: why do buttons disappear when they are clicked in that sequence?
This is because when start() is called it grids the first image, then when rightpic() gets called, it checks what is the value of cimage and acts accordingly, since when you first start the program the value is set to "flower1.jpg" it evals the first if statement and forgets the first image gridded and grids the second image, then you call close(), again it checks the image and removes everything, however, cimage is now "flower2.jpg" and when you call start() again it grids the first image, but when calling rightpic() it goes to the elif cimage == "fower2.jpg" but since the second image is not gridded yet, there is nothing to forget, so it simply grids the third image below the first one and since the other buttons are place()d then this grid method as it was called after place() now puts the third image over those buttons.
The solution is to simply do this:

Try using Session with HttpContext as below:-

You can use data-attribute for both your div where image is added and input field .So, whenever new file is uploaded you can use setAttribute("data-id", count) here count can be any random number only make sure this value should be same for both input and div because this will help us to remove and sort inputs .

Now , for sorting inputs you can use stop event this will get called when sorting is stop .Inside this you can loop through dropzone div and then get attribute which we have added earlier using this attribute we can find the input and append same to botofform div.

Finally , for deleting files you can use remove files event this will get called whenever remove link is clicked so here you simply need to get that data-id which is added to div then use this attribute to remove input as well.

Demo Code :

Though you have correctly defined your recyclerView with Glide library to show the picture but you are not storing(saving) picture information in your database.

Is there a reason why you use Dialog-based app? It's very limiting...

The Document-View architecture provides CScrollView that will do everything for you.

Here is my solution:

You should use PIL.Image.resize() function to resize the image:

You need to use mask for this and not clip-path. You define the size and then you adjust the position. It works the same way as background-image.

Here is a basic example:
