Bitmap vs Vector Graphics
| Aspect | Bitmap (Raster) | Vector |
|---|---|---|
| Storage | Grid of pixels with color values | Mathematical formulas (lines, curves, shapes) |
| Scaling | Pixelated when enlarged | Perfect at any size (resolution-independent) |
| File Size | Large - depends on resolution | Small - just stores formulas |
| Best For | Photos, realistic images, complex scenes | Logos, diagrams, fonts, illustrations |
| Examples | JPEG, PNG, BMP, GIF | SVG, PDF, AI, EPS |
| Editing | Pixel-by-pixel (Photoshop) | Move/resize shapes (Illustrator) |
