The Magic Wand tool is used for bitmap processing. If we want to select the same color in the bitmap, you can set the Magic wand properties first. Click the Magic Wand Properties button to set the following options in the Magic Wand Settings dialog box that pops up: for thresholds, enter a value between 1 and 200 that defines the degree of color proximity that must be reached for adjacent pixels to be included in the selected area. The higher the number, the wider the range of colors included. If you enter 0, only pixels that are exactly the same color as the first pixel you click are selected. For smoothing, select an option from the pop-up menu to define the degree of smoothness of the edges of the selected area, as shown in Figure 2-2-32.
