I recently just started in photoshopping since I want to make 2D games for a project. I found some really cool images that I'd like to use for my game. However, the image I found couldn't be extracted properly by the game engine. So now, I have to edit the image to have a white back ground or a black and white like this
how do I turn the background like the first image, I also need to remove the text and unnecessary stuff for 2D animations.
