Graphics
Bitmapped Graphics
Advantages of using Bitmapped Graphics
Very like manual tools such as paint brushes
use of spray type facilities
Ability to rub out areas, edit single pixels
Disadvantages of using Bitmapped Graphics
Uses large amounts of memory
Resolution dependant
Cant be resized
How are Bitmapped Graphics Represented?
Bitmapped Graphics are represented as a
grid of pixels
. Each pixel uses a certain number of bits to store the
colour of each pixel
. The more bits used to represent each pixel, the more colours that can be represented
Vector Graphics
Examples of Vector Graphic Shapes
Rectangle
Ellipse
Line
Polygon
How is a Vector Graphic represented?
In a vector graphic, the picture is stored as a collection of mathematically determined shapes or objects, also called attributes. Each object in the picture has properties such as
start x and y coordinates
fill colour
line colour
width
height
Advantages of using Vector Graphics
Takes up less amounts of memory as only information about the actual drawing is kept
Resolution independent
Easy to alter the size and shape of graphics
Disadvantages of using Vector Graphics
Cant rub bits out
