I'm building a Drupal website and I need to upload an image, some text and render that image with the text as overlay, maybe even a logo on top of it as well. Is there a module or a way to do this on Drupal 8?
Clarification: I need to generate a new picture and add overlay as pixel data.
Take a look at Image Effects module. According to readme it provides both - text overlay and watermark effects. If they are not sufficient for your needs you also have "ImageMagick arguments" effect, so nothing can stop you now ))
