A filter contains a color definition, displayed both as RGB and HSL values, and tolerances for variations in hue, saturation, and luminance, with respect to the defined color.
See Defining a Color by its RGB values on page 464 and Defining a Color by its HSL Values on page 464. The Color and the Tolerances can be set by entering values or by using the display and selec- tion tools that are in the Color Finder. To configure the color filter: 1. Set an initial color in one of the following manners: l Pick a specific color in the display: Under Selection Tools, select the "Color Selec- tion'' icon. Using the mouse, move the cursor in the image display and click once to select the color of the pixel where the cursor is placed. l Pick an average color in the display: Under Selection Tools, select the "Range Selection" icon.
Using the mouse, drag an area cursor in the image display. This calculates and selects the average color in the selected area. l Set the color RGB or HSL values: Enter values under R, G, and B, or under H, S, and L. The single color box above the "values" area provides a preview of the defined color. 2. Define Tolerances in one of the following manners: l Enter values for H, S, and L, in the Tolerances section. l In the Color Finder display, resize the bounding boxes to set tolerance values. As illustrated in the following graphic, the bounding box in the multicolored area sets tolerance ranges for hue and saturation.
The bounding box in the grey-level area sets a tolerance range for luminance. 3. Click OK to confirm changes and return to the editor. ACEUser's Guide, 3.6.x, 18316-000 Rev A Page 463
