Anti-aliasing in images and fonts is a technique used to smooth the appearance of edges and reduce the jagged, pixelated look known as “aliasing.”
- In images, anti-aliasing works by blending the colors of edge pixels with the background, creating a gradient that softens the transition between colors or shapes. This is particularly important for curves and diagonal lines, which can appear rough or stair-stepped without anti-aliasing.
- In fonts, anti-aliasing smooths the edges of text characters, making them appear more polished and readable on screens with lower resolutions. It does this by adjusting the intensity of pixels along the edges of characters to create the illusion of smoother curves and lines.
Overall, anti-aliasing enhances the visual quality of both images and fonts, making them look more natural and less harsh to the eye, especially when viewed at smaller sizes or lower resolutions.
