Chapter 8 – Image Compression

Compression

The file size of scanned images can be influenced in several ways:

 Select lossless compression for optimal results.

 The Compression ratio allows you to determine how many

times you want the scanned images to be smaller than their

original.

 You can also determine the desired target size of a single page

in the output file.

Indicate the file size for a single page from 1 KB to 10,240 KB. The

default value is 100 KB.

 Select a Quality factor to determine the degree of loss allowed

during the compression process.

Move the slide toolbar to select a value from 0 to 256: 0 guarantees

the highest image quality, 256 the best compression. The default value

is 128.

Optimization

 Optimize quality of text zones maintains a high quality for text

and table zones, reducing the quality of graphic zones in the

output images.

 Optimize quality of graphic zones has the opposite effect.

Note that character recognition must be enabled for these options to

be available; otherwise the system can't detect which zones contain

text and which areas contain graphics.
