SUBSTANCE: generation employs a method of searching for exact matching on all three channels RGB and optimised colouring in case of insufficient exact matching of colours. The data base of initial images is collated and the images are then sorted and a static and a dynamic coordinate grid are then superimposed onto the target image, where the image is placed in the cells of the grid. A tile-image is generated and then converted to digital form with possibility of transmission by electronic devices and printing on a printer. The initial image is broken into elements of fixed dimensions with possibility of changing dimensions of the cells depending on dimensions of the initial images. The initial image is selected from the sum of moduli of deviation on all three colour channels RGB. The initial image is corrected such that its average value becomes equal to the average value of the colour of the tile on the target image. Each initial image is then scaled to given dimensions and inserted into the corresponding position of the created tile-image.

EFFECT: high quality of tile-images and broader functional capabilities.
