1. Define Graphic & Image. What is the difference in the two?
Graphic is a type of visual presentation that can be seen on a physical surface like a drawing, illustration, symbol, etc. Image is a 2D or 3D representation of a person, animal, object, or in the real world that can be still or in motion.
2. Explain the difference between Raster & Vector images.
Raster images are made up of pixels while Vector images are made up of mathematical paths and lines. Vector images can be scaled to make the image larger and it will not lose it's quality; while Raster images would come out messy.
3. Why should you avoid upscaling whenever possible?
Upscaling can possibly ruin the image because when you upscale you don't redefine the pixel count or structure of the image.
4. What is the difference between Aliased and Anti-Aliased text?
Aliased text has that stair step/ jagged-edge effect to it due to it being made from squared pixels; while anti-aliased smooths out that effect.
