raszteren

Rasteren is a term derived from the Dutch word "raster," which means grid or lattice. In the context of digital imaging and computer graphics, raster refers to a method of representing images as a grid of pixels. Each pixel is a small dot of color, and the combination of these dots creates the image. This method is in contrast to vector graphics, which use mathematical equations to define shapes and lines.

Raster images are widely used in digital photography, web design, and video production. They are resolution-dependent, meaning that the quality of the image can degrade if it is enlarged beyond its original size. Common file formats for raster images include JPEG, PNG, and GIF. JPEG is often used for photographs due to its ability to compress images with minimal loss of quality. PNG is favored for images that require transparency or lossless compression. GIF is used for simple animations and images with a limited color palette.

The rasterization process involves converting vector graphics into raster images. This is often done using software that can handle both vector and raster formats. Rasterization is necessary for printing and displaying images on screens, as most output devices work with raster images.

In summary, rasteren refers to the representation of images as a grid of pixels, a method fundamental to digital imaging and graphics. It is essential for the creation, storage, and display of digital images, and it plays a crucial role in various applications across different industries.
