Raster vs. Vector Graphics in Digital Interfaces

Digital imagery in user interfaces is bifurcated into two distinct mathematical architectures:

1. Raster Graphics (Bitmap)

Constructed from a fixed grid of colored pixels.

• Formats: JPEG, PNG, WebP, AVIF, GIF.
• Behavior: Resolution-dependent. Scaling a raster image beyond its native pixel dimensions results in pixelation, blurring, and artifact distortion.
• Ideal Use Case: Complex photographs, detailed 3D renders, and textured illustrations containing continuous color gradients.

2. Vector Graphics

Constructed from mathematical paths, curves, points, and geometric primitives.

• Formats: SVG (Scalable Vector Graphics).
• Behavior: Resolution-independent. Can be scaled infinitely from a 12px micro-icon to a 4K billboard with zero loss of sharpness.
• Ideal Use Case: System icons, corporate logos, UI illustrations, and decorative geometric shapes.
