Extras and Beyond

magnified view; rather, it saves a rectangle that begins in the upper-left corner of the magnified view and contains all the dots in the view that are not the background color, plus a four-or-five-dot border around this area. Color Gadget: This gadget consists of a number of colored rectangles that reflect the number of colors you set in the ScreenMode editor and the color values you set with the Palette editor. The box at the top of the gadget displays the currently selected color. To change it, move the pointer over one of the other colors and click the left mouse button. Because you can have Workbench screens that display up to 16 colors, you can create 16-color icons with IconEdit. If you later switch your Workbench back to eight, four, or even two colors, however, the extra colors are lost.
The IconEdit color gadget has the interesting ability to let you select two col ors at a time. First, you select one color normally; then, shift-select another
color. In the selected color box, you'll see a color that looks like a mix of the two youVe selected. It is actually a checkerboard pattern of alternating dots of the two colors. This hybrid color isn't used when you draw simple points and lines; these use the first of the two colors you selected. The hybrid colors are instead used in the area-painting gadgets — Circle, Box, and Fill — that are discussed below.
Painting Gadgets: Below the color gadget are six small buttons with different shapes drawn on them. These are the painting gadgets: Freehand, Continuous Freehand, Circle, Box, Line, and Fill. The Painting gadgets act like radio but tons; when you select one, you deselect another. One painting gadget is always active.
Freehand Gadget: Active when you first open the IconEdit window, the Freehand gadget changes the color of the dot below the pointer whenever the select button is depressed. If you drag the mouse quickly, however, the gadget may not be able to color all the intervening dots between the old position of the pointer and the new one. The priority of the freehand gadget is to keep up with the pointer; it will skip intervening dots to do so. Continuous Freehand Gadget: This gadget differs in one significant respect from the freehand gadget. Its priority is not to keep up with the pointer, but to change the color of every dot you drag the pointer over. Thus, it may lag behind the pointer if you drag the mouse quickly, but it will not miss any intervening points.
Circle Gadget: One side of the imagery on this gadget, shows a hollow circle and the other shows a filled one. By selecting one side or the other, you can choose to draw either the perimeter of a circle or a completely filled one. The procedure for actually drawing hollow and filled circles is the same.
