In computer graphics, vector graphics represent visual images through mathematical descriptions of:
Multiple Choice Options
- A✓ Correct Option
Geometric paths (points, lines, curves, polygons)
- B
A discrete rectangular grid of pixels (raster bitmap)
- C
Fixed color lookup palettes
- D
Quantized DCT frequency blocks
Detailed Technical Solution & Explanation
Vector graphics define images mathematically using geometric primitives such as points, lines, curves, and shapes (paths), allowing images to be scaled indefinitely without loss of resolution or pixelation.
Option Analysis:
•
Option A (Geometric paths (points, lines, curve...): Correct. Fundamental definition of vector graphics.
•
Option B (A discrete rectangular grid of pixels...): Defines raster/bitmap graphics (JPEG, PNG, BMP).
•
Option C (Fixed color lookup palettes): Used in indexed raster images (like GIF).
•
Option D (Quantized DCT frequency blocks): Used in JPEG lossy raster compression.
