Pixelgrafiken

Pixelgrafiken, also known as raster graphics, are digital images composed of a grid of individual colored squares called pixels. Each pixel has a specific location and color value, and together they form the complete image. The resolution of a pixel graphic is determined by the number of pixels it contains, often expressed as width by height (e.g., 1920x1080 pixels). Higher resolution images contain more pixels, resulting in greater detail and sharper appearance.

Unlike vector graphics, which are defined by mathematical equations and can be scaled infinitely without losing quality, pixel graphics are resolution-dependent. When scaled up beyond their original resolution, pixels become visible, leading to a blocky or pixelated appearance. Common file formats for pixel graphics include JPEG, PNG, and GIF. These formats store image data by assigning color values to each pixel in the grid.

Pixel graphics are widely used in digital photography, web design, and digital art. They are suitable for representing complex images with subtle color gradients and textures, such as photographs. However, for images that require frequent resizing or sharp lines, such as logos or illustrations, vector graphics are often preferred. The creation and editing of pixel graphics are typically done using software like Adobe Photoshop, GIMP, or Paint.
