Objective: Understand the differences between raster and vector graphics.
Duration: 1 hour
Introduction to Raster and Vector Graphics
Overview: Raster and vector graphics are the two main types of digital images, each suited for specific purposes.
Key Concepts:
Raster Graphics: Pixel-based (e.g., JPEG, PNG). Best for photos, detailed textures. Resolution-dependent, may pixelate when scaled.
Vector Graphics: Path-based (e.g., SVG, AI). Ideal for logos, icons. Scalable without quality loss. Photopea supports vectors via paths/shapes.
Use Cases: Raster for web photos, vector for scalable designs.
Tools: Photopea (raster and basic vector), Canva (raster-focused, simpler interface). Why It Matters: Choosing the right graphic type ensures quality and functionality in design projects.
