I’m working on a Telegram bot that adds a ribbon to images. The issue I'm facing is that the ribbon appears too small or too large relative to the image size. I want the bot to automatically adjust the ribbon size to fit different image dimensions properly. Any suggestions on how to achieve consistent scaling across various image sizes?

Look at the image dimensions and make the dimensions of the ribbon some standard proportion of it?

The challenge is that the uploaded images vary significantly in dimensions. I'm looking for a solution that will scale the ribbon proportionally based on the image's size, ensuring it maintains a consistent look across different image dimensions. Any suggestions on the best way to achieve this?

You'll have to qualify the criterion "look".

Maybe pick a height with a fixed ratio of the image height, possibly adjust for the aspect ratio of the image. Maybe also with a minimum. Experiment.

The images I’m working with come in various dimensions, so the ribbon should adjust proportionally based on the image size. Ideally, I want the ribbon to cover a consistent percentage of the image’s width and height, no matter the dimensions. The position of the ribbon should remain fixed at the bottom center of each image

So the issue seems to lie with the varying image dimensions rather than the code itself? Is there a way for the bot to analyze the dimensions of the incoming image and automatically adjust the ribbon size accordingly? Ideally, I'd like the bot to calculate the appropriate ribbon dimensions based on the image measurements to maintain consistency across different image sizes

Receive the image. Inspect it for its size? The Pillow library parses most common formats.

Here are some pictures of what I tried

Would you say the first is pretty good and the second is too narrow and illegibly small?

[trim moon]

yup
