document analysis
When you scan a magazine page, for example, you want to scan it
at a high resolution, in color, so that it will look as good as the
original. XIF lets you do this.
However, you do not want the scanned image to take up a lot of
space on your computer. XIF’s built-in file compression
technology produces very compact files.
Later, you may want to search on the data contained in this
magazine page. Or you may want to extract a block of text, or a
picture, from this image. XIF’s document analysis technologies
enable you to do this, as well.
XIF achieves these goals by storing a scanned image in multiple
layers (Figure 4–9).
