Image File Types

Animated GIF Files

An animated GIF is a sequence of GIF files all bonded together and displayed on after the other.

JPEG Files

A JPEG files uses much more complex technique to compress images, like photographs, where the colour of every pixel is different

GIF Files

In a GIF Image, the number of colours is reduced to 256 and then "runs" of the same-colour pixels are encoded in a colour+numberOfPixels format

MPEG Files

An MPEG file uses a complex algorithm like a JPEG file does-it tries to eliminate repetition between frames to significantly compress video information

Shockwave Files

Shockwave provides a vector-based animation capability. Instead of specifying the colour of every pixel, a Shockwave file specifies the coordiantes of shapes as well as the colour of each shape

Vector Based Image vs Bitmap Based Image

Then, there are NxFiles. These are vector-based 3D files that allow user interaction. You can rotate and zoom in on a 3D object in any way you like. Bitmap images have to define the colour of each and every pixel

Real Art vs Digital Art

• Many people argue about the qualities of 'real' art and whether digital art is considered art.

   What number system is digital data based on? What two digits are used to code all digital data?

Binary code- numbers 0 and 1

What is a bit? What is a byte?

Bit-A basis unit in computing

Byte-a unit of digital information in computing and telecommunications

Sampling Rate-defines the number of samples per second taken from a continuous signal to make a discrete signal

Colour Depth(bit-depth)-is the number of bits used to represent the colour of a single pixel in a bitmapped image or video frame buffer. The amount of ‘bits’ there are effects the appearance of a photo in terms or ‘number of colours’

Top Left-1 bit(2 colours)

Top Right-2 bits(4 colours)

Bottom Left-4 bits(16colours)

Bottom Right-8 bits(256 colours)

Bottom Centre-16 bits(16,777,216 colours)/"truecolour"
