Horizontal scrolling with large images

Hello !

I am not entirely familiar with the process of opening issues or contributing to packages, so please excuse me if I am not handling it correctly.

I had this use case where I needed to scroll horinzontally in a really large image while still being able to clic and collect the position of the pixels. I ended up finding this solution adding the following chunks of code directly in the lib files :

style.css

#image-container {
overflow-x: scroll;
width: 100%;
max-width: 100%;
}

#image {
display: block;
height: auto;
width: auto;
}

index.html

<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="UTF-8" />
    <meta http-equiv="X-UA-Compatible" content="IE=edge" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <title>streamlit-image-coordinates</title>
    <script src="./streamlit-component-lib.js"></script>
    <script src="./main.js"></script>
    <link rel="stylesheet" href="./style.css" />
  </head>
    <body>
    <div id="image-container">
      <img id="image" />
    </div>
  </body>
</html>

Would this be a good idea to make it a permanent feature of the component ?

Cheers

Thanks that's so helpful. Can you also add a pointer/marker on click.
