The quality of the picture can also be assessed by its size. Raster graphics images containing , pixels ( in width by  in height) appear rougher than images containing ,, pixels ( by  in width and height, respectively). Characteristics of raster graphics Characteristics of raster graphics Such an array of graphic information often takes up a large amount of space. Therefore, to save memory, a compression method was developed in which little or no original quality is lost. Lossy compressed graphics are typically in the JPEG  format.

Examples of lossless compression include graphics files with the PNG and Australia WhatsApp Number Data  TIFF extensions. In this case, it is possible to return the modified image to its original uncompressed form. Lossy compression, such as JPEG, is performed by modeling pixel parameters using mathematical formulas and excluding certain details. This results in a significant reduction in the size of the graphic file. Permission The raster size increases by reducing the sharpness of the image. This function can be used on a wide scale for devices that display graphic information.



Raster graphics objects allow you to reproduce realistic images, which vector graphics cannot boast of. The latter is mainly used for drawing geometric shapes and text elements.

For printers, this figure can even be higher than  dpi. This leads to difficulties in choosing the most optimal image resolution for printing.
