What are Vector graphics made up of
Made up of lists of objects and their properties
What is a vector object
A mathematically/ geometrically defined construct (e.g. rectangle or circle) Have properties that determine dimensions, appearance and position
Where are vector properties stored
Stored in a list called a drawing list
Example for storing a circle object
< circle cx = “100” cy = “100” r = “50” fill = “lightgreen” stroke = “black” stroke-width = “5” /> cx & cy used to determine centre coords r used to determine radius of circle fill used to determine colour of inside Stroke used to determine border colour Stroke-width to determine border width
Advantages of vector graphics
• can be resized without distortion as they’re scaleable • smaller file size due to less info stored • easier to edit vector graphics as each object can be adapted independently • dont lose quality regardless of resolution
Advantages of bitmaps
• can be used to depict any level of complexity and detail • can represent images not composed of regular shapes
Examples of Vector Graphics
• Charts • Logos • Web designs
Examples of Bitmaps
• photographs • Scanned images
