Ch. 3 – Basic Program Mode−−−−Hue – The actual color, as distinguished from others in the color spectrum. Hue is derivedfrom a color wheel and is expressed in the color's angular location (e.g., 0 to 360 degrees).Saturation - The proportion of perceived pure hue in the color. Saturation (in the SPOTsoftware) is measured on a numerical scale of 0 to 100, where zero equals pure gray and 100equals pure hue (e.g., “day glow”).Original Color – A sample “swatch” of the color that you selected. The cross hairs on thecolor wheel (e.g., in the center of the window) indicate the relative position of the selectedcolor.The Modify Main Image box is checked as a default.4. Set the new color. This can be done in one of two ways, depending on whether the image shouldcontain white:−−Duplicate ImageIf you are trying to make the selected pixel in your image appear as white (or gray if thepixel is darker), click on the Make White/Gray button.If you are working with an image that does not have any white, modify the Hue andSaturation values so that the New Color “swatch” shows up as the color that you want. Youcan do this either by entering specific Hue and Saturation values, or dragging the cross hairson the color wheel to the desired location.Click on the Duplicate Image option to create a copy of the active (on-screen) image.Calibration and MeasurementThe Add Calibration Mark and Add Measurement options enable you to add calibration andmeasurement references to SPOT images. Refer to the Annotation – Calibration and MeasurementMarks section of Ch. 8 for detailed steps.AnnotateImage annotation is useful when you want to prepare captures for formal presentation, or inclusion in anarticle or reference work. Using SPOT’s image annotation features, you can:• Add text to an image.• Use an arrow, line, rectangle, or ellipse to emphasize a particular area in an image.• Add a graphic stamp such as a company logo to an image.• Add freehand lines to an image.To annotate an image, select Annotation from the Edit menu. Several changes take place in the SPOTimage-editing environment:• The Edit menu options change to reflect annotation editing.Refer to Editing Annotation Objects (Ch. 8) for descriptions of each option.• The Object menu appears with options for inserting drawing objects, text, images, and image relatedinformation onto an image. Cursor functionality in SPOT reports varies according to which Objectmenu option is selected.−−If None is selected, the cursor is an editing tool for selecting, sizing, and positioning objects.When creating new reports, None is the default option.If a report object is selected, the cursor changes to a cross-hair icon for placing new report objectson the grid. Refer to Adding Annotation Objects to SPOT Images (Ch. 8) for descriptions ofeach object.User Guide to the SPOT Insight Camera 51
