How to smoothen/enhance this image? I needed sharp, smooth lines.
I tried using many Gimp tutorials, but none showed good results. I tried to vectorize, but the edges were crooked. I also tried many AI websites, but none showed satisfactory results. At some point I even tried editing it manually, pixel by pixel, but I couldn't get the edges' gradient right.
It can be a black and white image of it, if it helps somehow (but I'll color it again using Gimp) . Thanks in advance.
