Compression

Compression is used to reduce the number of bytes needed for

 

scanned document images, thus saving storage space and/or

 

transmission time. This is accomplished with special algorithms

 

that use run-length encoding.

 

The scanner allows one of three types of compression:

 

TSS Group III, one-dimensional

 

TSS Group III, two-dimensional

 

TSS Group IV

 

NOTE: There are several standard options for Group III, one-

 

dimensional compression. The scanner always utilizes the

 

optional EOL (End of Line) and RTC (Return to Control)

 

codes. These codes are always padded so the code ends

 

on a byte boundary.

 

Results vary, depending upon image content; the more non-

 

standard run length that exists in the image, the less effective the

 

compression. A compressed document image may be 5 to 15

 

times smaller than the original document image; however, the

 

compressed image can also be up to 5 times larger than the

 

original document image for documents that contain large

 

numbers of non-optimum run-length (i.e., scanned or halftone

 

documents).

 

Compression is expressed in terms of a ratio. The ratio is a

 

measure of how well a digitized image can be compressed. A

 

compression ratio of 10:1 indicates a large reduction in file size

 

after compression. A compression ratio of 1:1 indicates no

 

reduction in file size after compression.

 

NOTE: Compression is recommended for all documents.

 

However, negative compression (less than 1:1) can occur;

 

it is most likely when screening or mixed mode/error

 

diffusion is enabled.

 

Refer to Chapter 6, Scanner-unique Commands for a description

 

of the FX/Y/Z command.
