Is there any good Scala or Java library for image manipulation? For simple tasks like composing an image with some others then generating a thumb?

they’re all a bit old school, and maybe inconvenient, but java.awt, java.awt.image, and javax.imageio has everything you need to blend and rescale images. You can find some blending example code e.g. here

you can find some examples of rescaling and generating image bytes e.g. here

there are probably newer/easier solutions, but these do work.
