Image versus graphics
Short answer
An image is a pixel grid captured from the real world, resolution-dependent and large; graphics are mathematical vector objects, scalable without loss and small. Images suit photos; graphics suit logos and diagrams.
Differentiate between image and graphics.
An image is a picture stored as a grid of pixels, usually captured from the real world. Graphics are pictures generated from a mathematical or geometric description of objects (lines, curves, shapes, colours).
| Point | Image (bitmap/raster) | Graphics (vector) |
|---|---|---|
| Stored as | Array of pixel colour values | Objects with attributes and equations |
| Source | Camera, scanner | Drawn or generated by program |
| File size | Large; depends on resolution and colour depth | Small; depends on number of objects |
| Scaling | Loses quality (pixelated) | Scales without loss |
| Editing | Pixel level; hard to move one object | Object level; easy to move, resize, recolour |
| Best for | Photographs, realistic scenes | Logos, diagrams, CAD, fonts |
| Formats | BMP, JPEG, GIF, PNG | SVG, CDR, AI, WMF |
