Define raster graphics1/4/2024 However, it is recommended that people who are not specialized or not qualified for the work of a graphic designer should begin to use raster graphics first because it is significantly easier to operate with than vector graphics, which is primarily used for professional purposes.Īs we can see from of the available data, in the mid 19th century, that is, in 1852, a raster photo was first made, whereas in 1880 the raster was officially introduced in the field of graphic reproduction. If someone has the desire to increase a raster photo, that is, to improve its resolution, he must know that it cannot be done without decrease its quality at the same time, and this is exactly what it is often mentioned as one of the flaws of raster graphics versus vector graphics. We are talking about BMP here or bitmap format, so it is precisely for this reason that JPG format is used more often, taking into account that it serves precisely for compressing a specific photo, but at the same time its quality is only slightly lost. Still, it should be emphasized that the raster implies a file that is not compressed, and hence all the images that are thus processed occupy a lot of memory space. Quite logically, if the color depth is greater, this means that much more shades of a specific color can be displayed, and therefore the quality of a photo is higher. Since the resolution is defined primarily as the total number of pixels, it is precisely on the basis that we can talk about the quality of a particular raster image, we note that in the same way the quality is viewed through the depth of color, which is actually the value assigned to each individual pixel. For this reason, photographs of this type certainly occupy significantly less space than those that are processed by the RGB principle. And if a black and white photo is processed through the raster, then only one bit is used for each pixel. Since each pixel, in this case, contains three bytes, then the color is defined for every single byte. In this case, the color is defined for each pixel when using the so-called RGB technique. It is actually about the fact that a particular image or data is represented through a network of pixels in the form of rectangles or by means of a network of colored dots on a particular device, such as a monitor, provided that this kind of graphics can also be printed out as well. One of the most common types of graphics is definitely raster, also known as a bitmap.
