How Big Is a COOL Image?
Most COOL systems use compression. Some use a simple blank space removal compression algorithm. (Any program is an algorithm, but algorithm is usually used to describe a specific well-defined operation such as compression.) Other systems add more sophisticated compression that can double the compression achieved with simple space removal. The estimates below can be used to do the initial sizing for the storage for a COOL system. After processing even one week of output, the exact size of an average COOL image can easily be determined. It is important to remember that there are often special cases. For example, end of month and end of year reports are frequently much different that daily or weekly reports. A statement, such as a utility or a bank statement may only contain a few line items. Most of these COOL page images are letter size or smaller and are less than 2 KiloBytes (2 thousand bytes). Statements make use of a forms overlay, overlaying an image of a standard form that include
