Can you explain the difference between vector and raster graphics?

Sample interview questions: Can you explain the difference between vector and raster graphics?

Sample answer:

  1. Type of Graphics:

  2. Vector Graphics: Defined through mathematical equations and points, creating smooth and scalable images.

  3. Raster Graphics: Constructed from individual pixels, forming a grid-like structure with fixed resolution.

  4. Image Quality:

  5. Vector Graphics: Can be scaled infinitely without losing quality due to their mathematical construction.

  6. Raster Graphics: Quality degrades when scaled up since pixels become enlarged and visible.

  7. File Size:

  8. Vector Graphics: Tend to have smaller file sizes compared to raster graphics.

  9. Raster Graphics: Often have larger file sizes due to the storage of individual pixel information.

  10. Editing:

  11. Vector Graphics: Can be easily edited by adjusting the defining points and curves without affecting image quality.

  12. Raster Graphics: Editing involves manipulating individual pixels, which can result in loss of detail and quality.

  13. Common Formats:

  14. Vector Graphics: Popular formats include SVG, EPS, AI, and PDF.

  15. Raster Graphics: Common formats are JPEG, PNG, GIF, and BMP.

  16. Suitable Applications:

  17. Vector Graphics: Ideal for logos, illustrations, line art, icons, and scalable graphics used in branding, print, and web design.
