anti-aliasing
Pixel boundary blurring
Anti-aliasing is a technique in computer graphics that smooths jagged edges on curved lines and diagonal shapes.
Digital images are made of square pixels, which creates stair-step patterns on anything not perfectly horizontal or vertical.
Anti-aliasing blends edge pixels with surrounding colors to create the illusion of smoother lines: Turn on anti-aliasing for cleaner text rendering.
