The 2D computer graphics have been evolved from the traditional drawing and printing technologies like cartography, advertising, typography, and technical drawing. Keep in mind that 2D computer graphics are representing by two-dimensional models. For your information the 2D computer graphics has been started in the year of 1950s, and it has been based on vector graphics devices. Over the decades, this sort of computer graphics is largely supplanted by raster-based devices.
The X Window system protocol and PostScript language have been the landmark improvement in this field. In most of the domains like engineering, desktop publishing, and business have fully based on 2D computer graphics technologies. It can be smaller than the equivalent digital picture. The presentation of 2D computer graphics is also more flexible from the time when it can be made at assortment resolution to outfit in various output devices. Due to these sorts of causes, the documents and files have often kept or broadcasted as 2D graphic files. The 2D graphics models might combine the geometric models (as well called the vector graphics), the digital images (or raster graphics), text being typeset (and defined by the content, size and font style, color, position or orientation), equations and mathematical functions, and lots more. All these components are been modified as well as manipulated by the 2dimensional geometric transformations like translation, scaling and rotation. In the object oriented graphics, image is been described indirectly by the object endowed with the self-rendering method—the procedure that assigns the colors to image pixels by the arbitrary algorithm. The complex models are built just by combining the easier objects, in paradigms of the object-and oriented programming. The convenient method to make the complex image is starting with the blank “canvas” the raster map (array of the pixels, known as the bitmap) filled with a few uniform color and “draw”, “paint” and “paste” easy patches of the color on it, in the appropriate order.
