Tag Windows Tool; To Create A Tag Window - Microtek ArtixScan 4500t Reference Manual

Tag Windows tool

The Tag Windows tool lets you set the shadow (black) point and highlight (white)
point of an image.
It also creates tag windows, which are used to isolate and identify precise colors
in a given image, providing a visible and retrievable record of color values. This
way, ScanWizard Pro lets you pinpoint and "tag" the color on the image, showing
you the original or "Before" values, as well as the corrected or "After" values
following the application of image adjustment controls. In the tag window are
Magic Diamonds, also for setting the shadow / highlight point, as well as to add /
remove a color cast.
The Tag Windows tool is useful especially if you are making color adjustments
based on known mathematical values, as the displayed color information
provides a basis for knowing how close or accurate are the color changes that
have been made.

To create a tag window

Click the Tag Windows tool, then move to any part of the preview image and
click. The tag window displays the x, y coordinates of the selected pixel and the
color value of that pixel (RGB, CMYK, Lab, etc.), depending on the selected
image mode selected.
