Microtek 35t plus User Guide

The Curve buttons allow you to modify the curve in the Curve dialog box. The buttons are the Pointer,
Zoom Frame, and Pane.

•      Use the 

Pointer

 button to define points in the curve that will be modified. When you

click on any point in the curve, a control point appears to mark your position. To
remove a control point, drag it off the graph.

Pointer

•      Use the 

Zoom Frame

 button to zoom in on a particular point in the curve. Once the

area is zoomed in, you can then use the pointer button to define new points for more
precision. This is particularly useful for working with 12-bit images, as more detail can
be seen in such images. The zoom level can be seen in the Zoom column (item #4 in
preceding page).

•      Use the 

Pane

 button to scroll through the curve if the curve has been zoomed in. The

Pane button can be used only if the curve has been zoomed in with the Zoom Frame
button (above). Otherwise, the Pane button will be dimmed.
