Is there a way to programmatically overlay text on a template image and create an output image file (PNG or JPEG)?

I am creating an interactive program that takes user inputs, queries backend system and returns the output to the user. I want this output to be displayed as an image.

I have a template image that has placeholders in place. I want to replace these placeholders with actual user information text from the backend systems and present it to the user as an image (PNG,JPG).

Is there an API that does this? Even a c# or NodeJS code will suffice at this point

Thanks in advance
