Hi Thomas, I love your tileset and purchased it. My game is 32 x 32 instead of 128 x 128, I tried to resize the image directly with both mac preview and photoshop however it will show thin layer of borders when use. How can i resize it properly? Thanks in advance.
I chose bilinear option when resize the image in photoshop then issue resolved. thanks.
As you already figured out, when resizing a filter will be applied. This usually mean that there will be "half pixels" that will be interpreted on to a half transparent pixel.
What usually works best is using "nearest neighbor" for scaling down when you need clear and sharp edges.
