They can be stretched/resized without any loss of quality. Vector graphics are usually used to create cartoons, clipart, animations or diagrams, often described as "line art". The Vector graphic's file information contains the mathematical instructions for the computer to present the objects on the screen in a specified order/arrangement, including length and direction of lines, within a defined area.
Raster graphic definition software#
Vector drawing, software programs are Adobe Illustrator or CorelDraw. Vector Graphics are composed of objects such as circles, boxes and lines, which are arranged or layered to present an image. A Raster image file can be in bitmap (1-bit), Grayscale (8-bit), Index (8-bit), RGB (24-bit), or CMYK (32-bit) colour. Raster images are also known as "bitmapped images".Ī Raster image is made up of pixels and the clarity depends on the resolution and size that it's printed at. The computer requires the information for the description of each pixel to recreate the image on your monitor, hence raster images can have a larger file size than vector images. Raster images are used for photographic images where there is continuous tone. Raster based programs include Photoshop, Paint Shop Pro, PhotoPaint, CorelPaint. It is simply by changing the colour of the pixels that you edit the image. Pixels that have adopted the background colour may give the illusion of gaps or holes in the image, but there are NO HOLES in a pixel based image. With a little distance the image is comprehensible and quite clear but up close the effect is "pixelated", that is it appears to break up.
It is the entire grid of pixels that make up the image, much as an impressionist artist creates an image through dabs of pure colour. Pixels are small squares of colour, alongside each other arranged in a grid.
