pixelsgrid

Pixelsgrid is a term used in digital imaging to describe the structured two-dimensional grid in which each cell represents the color and, optionally, the transparency of a single picture element (pixel). In this sense, a pixelsgrid is the fundamental data structure behind raster images, textures, and user interfaces where precise control over spatial sampling is required. There is no single standardized specification for pixelsgrid; the term is used descriptively in various contexts to refer to the grid-based organization of pixel data.

Definition and scope: The grid is defined by its resolution (width by height) and color depth. Each grid cell contains color channels (for example RGBA) and may include alpha information. The grid is typically stored in memory in a row-major layout, though other layouts exist to optimize hardware access. Depending on the application, additional metadata such as color space or gamma information may accompany the grid.

Operations: Common operations on a pixelsgrid include sampling, nearest-neighbor and interpolation methods, color space conversion, and compositing. In graphics pipelines, pixel data is read from a grid during rasterization, shading, and texture lookup. Large images may be divided into tiles or chunks (tiles) for efficient rendering and streaming, enabling scalable rendering and memory management.

Applications and variations: Pixelsgrid underpins image editing, game engines, and GPU textures, supporting pixel-perfect rendering, filtering, dithering, and procedural generation. Color depth ranges from 8-bit per channel to higher bit depths, and grids can be compressed or tiled for efficient storage and transmission.
