Scaling box
The scaling combo box allows you to specify the
horizontal and vertical scale of the image to be scanned.
Note that the maximum and minimum scaling is
determined by the resolution.
The scaling unit is a percentage (%). You may select a scaling percentage from the
list. The value selected applies to the horizontal and vertical coordinates. To
customize the scale, you may select the Custom... item to invoke the Custom
Scaling dialog box shown below:
From this dialog box, you can adjust
the scales of the X (Horizontal) and Y
(Vertical) axis independently by
dragging the scroll bars. This may
cause the scale of the X-axis to be
different from that of the Y-axis.
Consequently, the shape of the original
image will be altered. To avoid this,
you can check the Sync check box to
adjust the scales of the X- and Y-axis
simultaneously. This will retain the
original shape of the image.
When you get the desired effect, click on the OK button to confirm your settings
and close the dialog box. If you are not satisfied with the adjustment, click on the
Cancel button to cancel your settings and close the dialog box.
Filter box
The Filter combo box allows you to sharpen or blur an
image. You can choose from the list: No filter ,
Sharpen , Sharpen more , Blur , Blur more and
Unsharp Mask… .
If you want the edge of the image to be sharper, i.e., in a higher contrast against
the background, select sharpen or sharpen more. If you select Blur or Blur more ,
the edge of the image will be blurred. If you want to adjust the sharpness more
accurately, select Unsharp Mask… and the Unsharp Mask dialog box will
appear:
