A Raster Graphics Editor is a software application used to create and manipulate images made up of pixels, known as raster images. These images are commonly used in digital photography and web graphics. Popular raster graphics editors include programs like Adobe Photoshop and GIMP, which allow users to edit photos, create digital art, and apply various effects. In a raster graphics editor, users can perform tasks such as cropping, resizing, and adjusting colors. The editing process involves working with layers, brushes, and filters, enabling artists and designers to achieve detailed and complex visual effects. Raster graphics are resolution-dependent, meaning their quality can diminish when scaled beyond their original size.
