What’s the difference?• 2D – x(width) and Y (height) axis• 3D – x(width) and Y (height) axis
AND Z (depth)

PalettesCommon Palettes
• 1 – bit (dwicolor)• 4 – bit (16 color)• 8 – bit (256 color)• 16 – bit (Thousands
colors)• 24 – bit (millions colors)
Higher bit = rich color 256-colors, VGA, 8 bit

Dithering…Color value pixel define to the closest matching color
Example:Scanned image …24-bit scanned image (millions colours) to 8-bit (computer)
