Pikseliruudukkoon

Pikseliruudukkoon, often translated as "pixel grid" in English, refers to the fundamental structure of digital images. It is a two-dimensional array of individual elements called pixels. Each pixel represents a tiny, indivisible unit of color or intensity within the image. Imagine a mosaic; a pikseliruudukkoon is like the entire surface of that mosaic, composed of countless small tiles, where each tile is a pixel.

The arrangement of pixels in a grid allows for the representation of complex visual information. The number of pixels in a grid, both horizontally and vertically, determines the image's resolution. A higher resolution means more pixels are packed into the same space, resulting in a more detailed and sharper image. For example, a 1920x1080 resolution image has 1920 pixels across and 1080 pixels down, totaling over two million pixels.

Each pixel within the pikseliruudukkoon has a specific location defined by its row and column coordinates. Furthermore, each pixel stores information about its color. This color information is typically represented using color models such as RGB (Red, Green, Blue) or CMYK (Cyan, Magenta, Yellow, Black), where a combination of values determines the final hue, saturation, and brightness of that individual pixel. The collective arrangement and color values of all pixels in the grid create the complete digital image that we perceive.
