Resolution settings

The settings related to resolution include the resolution box, the resolution list
box, and the resolution unit.
Resolution is the sampling of image pixels per measurement unit or the amount
of pixel information stored in an image. Together, the image resolution and
dimensions determine the file size of the image, which is measured in kilobytes
(KB) or megabytes (MB).
The resolution of an image is important in determining the quality of the output
image. Resolution is also directly related to file size, and the higher the
resolution, the larger the resulting file size will be.
When dealing with resolution, remember to distinguish between optical
resolution and interpolated resolution.
Optical resolution is the "real" resolution as measured by the scanner's optics.
Interpolated resolution is software-enhanced resolution and can be useful for
enlarging very small images or for printing line art to obtain superior results.
A. Resolution list box
This shows the resolution setting. To set your resolution:
Enter a resolution setting in the Resolution edit box, then press Enter. If the
value you enter is too low or too high, the minimum or maximum resolution
value is entered for you instead.
According to the image type you select, the default resolution is displayed. When
you specify the resolution you need, this value is recorded for subsequent use.
ScanWizard Pro TX records last 6 different resolution settings.
