PostScript pixel management in computer graphics

The paper shows the possibility of program manipulation of pixels in computer graphics. In practice, pixels are usually square, since many programs have only such a possibility of manipulation. All solutions in this work were created using the PostScript programming language. PostScript is a relatively easy language to learn, capable of managing every smallest component of an image, i.e. pixels. The transformation matrix in PostScript, with its six parameters, completely controls the size, slope, and appearance of the pixels. By managing the parameters in a controlled way, pixels are no longer ordinary squares, but take on new shapes. The introduction of pseudo-random numbers into image management algorithms creates individual and unique solutions that can be used not only in computer graphics, but also in security printing.
