So, a while back I was looking for ways to improve the textures of a particular game, and I came across a Pixel Smoothing algorithm for the game Terraria.
I particularly had an interest in using this with the minecraft textures, as they are each seperated into image files. This filter takes the pixels around an area and its color, and apparently the algorithm generates the image solely on that?
However, terarria has some sprites Merged with Frames and Gridlines, and it causes grahpical errors and stretched sprites. So its not completely compatible with it.
Heres the link to the particular post: https://forums.terraria.org/index.php?threads/enhanced-version-of-the-textures-of-terraria-1-3-0-8.39115/
As you can see, I want to create THIS effect with any pixel based photo, is something like this possible with a basic algorithm or extension for PDN, or maybe just a program or site online that can create this effect?
See the Sprites below that the XNB filter was applied to.
If anyones got any idea of what this effect may be Called, or if they have resources to show me where and how I could create this effect myself, please answer below.
