#!F-adobe-helvetica-medium-r-normal--18* #!N #!CDarkGreen #!N #!Radconp Adding Control Points #!N #!EC #!N #!N Control points can be added to an area using one of four different methods: #!N #!I0 #!N #!F-adobe-times-medium-r-normal--18* #!N #!N #!I30 #!N o double-clicking directly in the area, #!N #!I30 #!N o using the #!F-adobe-times-bold-r-normal--18* Add Control Points... #!EF dialog box, #!N #!I30 #!N o using the #!F-adobe-times-bold-r-normal--18* Generate Waveforms #!EF dialog box, or #!N #!I30 #!N o copying and pasting control points from another area. #!N #!I0 #!N #!EF #!N #!N #!N To add a new control point by double-clicking, place the cursor on the location where you want the new control point, then double-click. The values between control points are linearly interpolated by the Colormap. If a new point is added as the bottom- or top-most point on the line, the new line continues vertically from the new point to the #!F-adobe-times-bold-r-normal--18* min #!EF or #!F-adobe-times-bold-r-normal--18* max #!EF value, respectively. When a new control point is added, its data value is displayed by default. #!N #!N To specify exact values for new control points, click on the #!F-adobe-times-bold-r-normal--18* Add Control Points... #!EF option on the #!F-adobe-times-bold-r-normal--18* Edit #!EF menu. The #!F-adobe-times-bold-r-normal--18* Add Control Points #!EF dialog box appears, as illustrated in #!Ladctpts77,dxall367 f Figure 77 #!EL . The #!F-adobe-times-bold-r-normal--18* Add Control Points... #!EF dialog allows you to specify values using two steppers. The "Data value" stepper allows you to specify a control point value between "min" and "max." The second stepper displayed in the dialog will reflect that area (Hue, Saturation, Value, or Opacity) is currently selected in the Colormap Editor. For example, if Saturation is the selected area, the dialog will display steppers for "Data value" and "Saturation value." The value for Hue, Saturation, Value, or Opacity can be a value between 0 and 1. Use the #!F-adobe-times-bold-r-normal--18* Add #!EF button to add the control points to the selected area in the Colormap Editor. #!Cbrown #!N #!F-adobe-times-medium-r-normal--18* #!Radctpts77 #!N Graphics omitted from Online Documentation.
