- I was wondering as image formats, what pdf (eps, ps) and djvu are classified into, raster image, vector graphic image?
- I think pdf (eps, ps) and djvu can all contain both raster image and vector graphic image, so are they hybrid image?
PDF's are largely comprised of vector elements and AI treats them as vector (e.g., you can open/edit/save). Yes, they can contain raster elements, but it treats them as vectors and attempts to scale them as it does embedded fonts and illustrations. Call it a hybrid if you will, but the raster support is more a concession than original intent.
