libGDX - make border around an image

Newbie & Debugging Questions
#1

Whats up programmers, well i have a question, can i make a border around an image? I have lots of blocks in 2D, and when the player hovers with the mouse on one of them i want to display the border around the texture / image.

Is it possible with code or should I make a separated image with the texture and border around it? Any ideas?

Thanks in advance :smiley:

just render a rectangle. I would use Shaperenderer.class or a shader.
