Integer scaling
Integer scaling, or pixel-perfect scaling, is a method for image upscaling (enlargement) with no blur and no distortion.
Turns each pixel into a square or rectangular group of integer number of same-color pixels. Prevents sharpness loss in videos and 3D games when scaling Full HD to 4K and maintains pixelation in old and pixel-art games.
