How is the encoding of graphic information in the computer?
In the middle of the last century, in connection with the need for visual representation of data, the coding of graphic information began to emerge. To date, we
As we know, encoding information is a very time-consuming, but necessary, process, since the computer works only with machine codes. Video, text, pictures - all this in a digital format is converted into a combination of zeros and ones. How is the coding of graphic information?
If you look at the monitor with a tenfold increase, you can see that it consists of
Modern LCD screens are able to reproduce more than 4 billion shades. For comparison: some thirty or forty years ago, the palette of computers consisted of 16 colors!
Coding graphic information also allows you to convert an image into a vector format. A vector image is a way of representing objects using the simplest geometric figures: points, lines, curves, polyhedra. Their position on the screen is determined by coordinates, and you can also adjust the color, thickness and drawing lines. Due to its structure, many devices are oriented to work with raster images, so the graphics in the vector view are usually preliminary, before being displayed on the screen it is processed by special programs.
Binary coding of graphic information in the form of text is performed on the same principle as video and image encoding .
