pixelbasiertes

Pixelbasiert refers to a method or system that relies on the fundamental unit of a digital image, the pixel. In digital graphics and imaging, pixels are the smallest controllable elements of a picture displayed on a screen. They are arranged in a grid, and each pixel has a specific location and color value.

In a pixelbasiert approach, operations are performed directly on these individual pixels. This is in contrast to vector graphics, which use mathematical equations to define geometric shapes and lines. Pixelbasiert graphics, also known as raster graphics, are common in digital photography, scanned images, and most computer-generated images seen on displays.

The resolution of a pixelbasiert image is determined by the number of pixels it contains, often expressed as width x height (e.g., 1920x1080). Higher resolution means more pixels and therefore greater detail, but also a larger file size. When a pixelbasiert image is scaled up beyond its original resolution, the individual pixels become visible, leading to a blocky or "pixellated" appearance. This is a key characteristic and often a limitation of pixelbasiert systems. Image editing software like Photoshop primarily works with pixelbasiert images, allowing for detailed manipulation of each pixel's color and transparency.
