FIELD: information technology.
SUBSTANCE: method of compressing graphics files involves predetermining the number of gradations of reducing geometric dimensions of a source frame of a graphic image. For each gradation, geometric dimensions of the source frame of the graphic image are reduced, compressed and stored in a compressed file, and then latter decompressed and enlarged to the initial size. Pixel values of the enlarged decompressed frame are then subtracted from pixel values of the source frame of the graphic image and the result with values of the contrast element loop is compressed in form of a file. All values of the reduced compressed files and corresponding values of the compressed contrast element loop are then summed. The least of the obtained sums is selected as the result.
EFFECT: high rate of data transmission.
