rastrowych

Rastrowych is the genitive plural form of the Polish adjective rastrowy, used to describe nouns related to raster data or raster graphics. The term stems from raster, a regularly spaced grid of cells or pixels employed to represent image data.

In digital imaging, raster graphics encode images as a matrix of discrete pixels. Each pixel stores color information, and the overall appearance depends on resolution and color depth. Raster images are edited on a pixel basis and are inherently resolution‑dependent, so scaling can reveal blocky artifacts. Common file formats include JPEG, PNG, GIF, TIFF and BMP, each with different compression and color‑support characteristics. Raster data can be processed with operations such as filtering, resampling and interpolation (nearest neighbour, bilinear, bicubic) during resizing or transformation.

In geographic information systems and remote sensing, rastrowe data describe phenomena across a geographic grid. Each cell (pixel) holds a value representing a variable like elevation, temperature or land cover. Raster models are contrasted with vector models, which use points, lines and polygons to represent features.

The term rastrowych appears in Polish texts to qualify nouns in the genitive plural that pertain to raster topics, for example in phrases like formatów rastrowych danych or obrazów rastrowych. It is primarily a grammatical form rather than a separate technical concept, and it is used in contexts where the subject matter concerns raster graphics or raster data.
