Rasterieditorit

Rasterieditorit, often referred to as raster graphics editors or bitmap editors, are software applications used to create and manipulate digital images. These editors work with pixel-based images, meaning they represent images as a grid of individual colored squares called pixels. Each pixel has a specific color value, and the editor allows users to modify these values directly.

Common functionalities of raster editors include drawing, painting, and retouching. Tools such as brushes, pencils, erasers, and fill buckets enable users to add or remove pixels, change their colors, and create various artistic effects. They also provide features for image adjustments like brightness, contrast, saturation, and color balance, which are essential for enhancing the visual quality of photographs.

Selection tools are a key component of raster editors, allowing users to isolate specific areas of an image for targeted editing. These tools can range from simple rectangular or elliptical selections to more complex lasso and magic wand tools that can select areas based on color or shape. Layers are another fundamental concept, enabling non-destructive editing by allowing users to work on different elements of an image independently.

Raster editors are widely used in graphic design, web design, digital photography, and digital art. Popular examples of raster editing software include Adobe Photoshop, GIMP (GNU Image Manipulation Program), Krita, and Paint.NET. The output of these editors is typically saved in raster image formats such as JPEG, PNG, GIF, and TIFF. The resolution of a raster image, defined by the number of pixels, directly impacts its quality and scalability. Enlarging a raster image beyond its original resolution often results in a loss of clarity and pixelation.
