Use this tool to create a selection around a connected area of similar pixels. When you click the Freehand Selection Tool button and move the cursor over an image frame, the cursor will take shape of a magic wand. Position the cross over the area you want to define as selection and click the left mouse button. To select the Magic Wand tolerance settings, double-click the brush tip sample on the Palette Bar. The Tool Settings dialog box will appear with the Tolerance options at the bottom. Indicate the desired threshold for hue, lightness and saturation in the Hue, Light and Sat boxes respectively. When you click a certain point in an image, ImageWarp uses the tolerance settings to determine how similar in color are adjacent pixels to the pixel in the current point. If a pixel lies within the tolerance range, ImageWarp includes it into the selection region. Low tolerance makes ImageWarp include pixels within a range of color values close to the pixel in the current point. High tolerance allows ImageWarp to include pixels within a broader range.
To add an additional region to a current selection, hold the SHIFT-key. The cursor will take a shape of a magic wand with a small "+" sign next to it. Use the described procedure to define a new area of similar connected pixels. The new selection will be added to the current one and the selection marquee will be rearranged to outline the combined selection area.
To subtract a region from a current selection, hold the ALT-key. The cursor will take a shape of a magic wand with a small "-" sign next to it. Use the described procedure to define a negative area of similar connected pixels. The new selection will be subtracted from the current one and the selection marquee will be rearranged the resulting selection area. If you create a negative selection area on an image with no current selection, a full-size rectangular selection will be automatically created and the defined negative region will become "a hole" in it.
Note that these operations neither affect the image, nor change a Standard Selection to a Floating Selection. See Working with Selections for more details.
