Detailed explanation-1: -In computer graphics, pictures or graphics objects are presented as a collection of discrete picture elements called pixels. The pixel is the smallest addressable screen element. It is the smallest piece of the display screen which we can control.
Detailed explanation-2: -The process of representing continuous picture or graphics object as a collection of discrete pixels is called Scan Conversion.
Detailed explanation-3: -The seven basic elements of graphic design are line, shape, color, texture, type, space and image.
Detailed explanation-4: -Raster graphics represents images by bitmaps stored in computer memory and displayed on a screen composed of tiny pixels. Each pixel is represented by one or more memory bits. One bit per pixel suffices for black-and-white images, while four bits per pixel specify a 16-step gray-scale image.
Detailed explanation-5: -Rasterization: The process of determining appropriate pixels for representing picture or object on screen is called rasterization. Scan conversion: The process of representing continuous picture or object as a collection of discrete pixel is called scan conversion.
