Painting packages

A painting application allows freehand drawing and colouring, usually with a mouse. Generally the features are:

  • a palette from which the user can choose colours
  • freehand pens and brushes offering different styles and line thickness
  • a range of standard shape tools such as rectangles and circles
  • colour fill tools
  • spray cans and eraser tools
  • cut, copy and paste
  • zoom (to work in finer detail)

Bitmap graphics

Bitmap graphics made with painting packages consist of many tiny dots called pixels. It is possible to edit each individual pixel.

Since the computer has to store information about every single pixel (the colour for example) in the image, the file size of a bitmap graphic is often quite large. Bitmap graphics lose quality when they're resized.
