Sometimes you may want your graphic to appear as though it has no background or border of it's own, as though it is a free standing object or floating on top of the page background. Photographs saved in GIF format lose some of the colour quality. Because of the limited colour depth, GIF compression works best with images with large blocks of the same colour. Gifs present the graphic as an 8-bit image or less which means that it is restricted to using only 256 colours so is generally a very small file size. gif A format by Compuserve Graphics Interchange Microsoft coined the term Bitmap for it's version of a Raster graphic format. cgm Computer Graphics Metafile also a common ClipArt format cdr CorelDRAW package produces this form by default

wmf or Windows Metafile for basic graphics. When you are creating graphics for the web you can only save them in GIF or JPG. These are simply different ways of describing the instructions for the appearance of the graphic to the computer. If you have created graphics for printing you may have saved them as.
When these graphics are re-sized they do not lose their colour or do not "break up". Originally they were simple drawings that appeared in Black and White but now they can be coloured and more elaborate. Vector graphics are also referred to as "object orientated".Īn example of these files would be Windows Metafiles (.wmf) or Windows ClipArt.
They are used widely on the Web because of their small file size. 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.

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.
