Computer Graphics Digital Painting Illustration

There are two main types of tools used for digital illustration: bitmapped (also known as "raster") and vector applications. Bitmap applications are commonly called "painting" programs, while vector applications are called "drawing" programs. These terms reflect the difference in look-and-feel between the images created in each type of program. With a bitmap application, the content is stored digitally in fixed rows and columns of pixels, which can be created in separate layers for more easily isolating and manipulating different parts of the image. A bitmap image contains information about each pixel's hue (color), luminance (brightness), and saturation (intensity of color). When the pointing device moves over an area of the image, new colors and values are applied to the underlying pixels. Painting tools allow the easy creation of "fuzzy" imagery, including effects such as glows and soft shadows, and textures such as fur, velvet, stone and skin, and are heavily used in photo-retouching.
With vector-based tools, the content is stored digitally as resolution-independent mathematical formulae describing lines (open paths), shapes (closed paths), and color fills, strokes or gradients. Vector paths are constructed of anchor points and path segments by using the pointing device to click and drag. Drawing tools typically create precise lines, shapes and patterns with well-defined edges and are superb for working with complex constructions such as maps and typography. Digital illustrations may include both raster and vector graphics in the same work. A bitmap image file may be saved in a format which embeds a layer of vector information, and vector image file may include imported bitmap images.
