Vector Graphics
Vector graphic images are represented as mathematical formulas that define all the shapes in the image. Vector graphics are more flexible than bit-mapped graphics because they look the same even when you scale them to different sizes. In contrast, bit-mapped graphics become ragged when you shrink or enlarge them.
Fonts represented with vector graphics are called scalable fonts, outline fonts, or vector fonts. The best-known example of a vector font system is PostScript. Bit-mapped fonts, also called raster fonts, must be designed for a specific device and a specific size and resolution.
.eps
Abbreviation of Encapsulated PostScript (pronounced as separate letters), EPS is the graphics file format used by the PostScript language. EPS files can be either binary (Mac) or ASCII (PC). Files in EPS format often end with a .eps extension.

Bit-map Graphics
A Bit-map is a collection of pixels that describes an image, A representation, consisting of rows and columns of dots, of a graphics image in computer memory. The value of each dot (whether it is filled in or not) is stored in one or more bits of data. For simple monochrome images, one bit is sufficient to represent each dot, but for colours and shades of gray, each dot requires more than one bit of data. The more bits used to represent a dot, the more colors and shades of gray that can be represented.
The density of the dots, known as the resolution, determines how sharply the image is represented. This is often expressed in dots per inch (dpi ) or simply by the number of rows and columns, such as 640 by 480.
To display a bit-mapped image on a monitor or to print it on a printer, the computer translates the bit map into pixels (for display screens) or ink dots (for printers). Optical scanners and fax machines work by transforming text or pictures on paper into bit maps. Bit-mapped graphics are often referred to as raster graphics.

.tiff
Acronym for Tagged Image File Format (pronounced tiff), One of the most widely supported file formats for storing bit-mapped images on personal computers (both PCs and Macintosh computers). Other popular formats are BMP and PCX. TIFF graphics can be any resolution, and they can be black and white, gray-scaled, or colour. Files in TIFF format often end with a .tif extension.
Remember, all these formats will be available on your client login page and on the CD provided.
