                      ILLUSTRATIONS                                                                         B1

                          LEARNING OUTCOMES

                         The student will be able to:
                            understand raster illustrations.
                            understand vector illustration.
                            understand file formats.
                            understand 2D shapes in graphics.

                      Illustrations are visual representations created to explain, decorate, or enhance a concept, story,
                      or idea. They can be hand-drawn or digitally created and are used in books, advertisements,
                      websites, and more.

                                RASTER ILLUSTRATIONS

                      Raster images, also known as bitmap images, are made up of a grid of pixels. Each pixel has a
                      fixed colour value, and when these pixels are viewed together, they create an image. However,
                      raster images lose quality when scaled up because the pixels become more visible, leading to a
                      blurry or pixelated appearance.

                                VECTOR ILLUSTRATION

                      Vector illustration is a type of digital image made using lines, shapes, and curves instead of tiny
                      dots (pixels). These images are created using maths, which helps them stay clear and sharp no
                      matter how big or small they are. This makes them great for logos, icons, and illustrations that
                      need resizing.

                      CHARACTERISTICS OF VECTOR ILLUSTRATIONS

                      Vector illustrations have several key characteristics that make them ideal for various digital and
                      print applications.
                         ∑  Scalable: They can be resized without losing quality.
