Units of Measurement

In the Units text boxes, the expression of width and height, in inches, centimeters, or pixels, of the scanned image. The preset unit of measurement is based on the Measurement System setting of the Regional Settings in your Windows Control Panel.

White-Point Eyedropper

The Histogram tool that lets you select the lightest portion of the image in the preview area. When you click on the image with the White-point eyedropper, all tones lighter than the selected sample tone are adjusted to white.

Width

The Width text box contains the width of the current selection or, if there is no selection, the maximum horizontal output size, based on the currently selected paper size.

Width-Height Ratio

Proportion of the image. To keep the width-height ratio intact, click the Keep Proportions button before changing the width or height values.

X and Y Axes

The X and Y axes on the Tone tab curve chart represent, respectively, the input image color and output image color.

Zooming

Enlarging an image or a selected part of the image in the preview window or in a graphics application.
