  83.     <h2>Magic Wand</h2>
  84.     <p>The Magic Wand tool allows you to select areas of color similar to the
  85.     way the other selection tools allow you to select a given shape.  Unlike
  86.     the other selection tools, however, the Magic Wand tool takes into
  87.     consideration factors such as the actual content of the image and the
  88.     current <a href="ToolsWindow.html#Tolerance">Tolerance</a> setting. In many cases, all that needs to be done to
  89.     select a given area of the image is to simply click on it.</p>
  90.     <p>You may think of the Magic Wand as working similarly to the Paint Bucket, 
  91.     except that instead of filling the area with color it will select that area.</p>
  92.     <h3>Tolerance</h3>
  93.     <p>Similar to the <a href="PaintBucket.html">Paint Bucket</a> tool, Magic
  94.     Wand's results can be adjusted by tuning the 
  95.     <a href="ToolsWindow.html#Tolerance">Tolerance</a>. The effect of adjusting the tolerance value is shown below:</p>

  141.     <h2>Advanced Use</h2>
  142.     <h3>Selection Building</h3>
  143.     <p>Sometimes it is not possible to select a given region using only one
  144.     click. Frequently, getting just the right selection can be difficult when
  145.     the desired area is not near one solid color. To make selections like this,
  146.     it works well to repeatedly use the Magic Wand with a low tolerance value,
  147.     extending the selection each time to capture slightly more of the desired
  148.     region with each click.</p>

  165.                     Magic wand being used multiple times, extending the

  171.         </table>

  173.     <h3>Selection By Exclusion</h3>
  174.     <p>It also works well to make a basic selection with a tool such as the
  175.     lasso tool, then use Magic Wand to refine the selection. This method is
  176.     particularly effective when the subject is identified by the lack of fine
  177.     detail outside of a given region.</p>

  196.                     An initial selection is made using the lasso tool, then
  197.                     the Magic Wand tool is used to exclude the area that is
  198.                     not intended to be selected by clicking in the region
  199.                     to exclude with the right mouse button.

  206.     <h3>Global Selections</h3>
  207.     <p>The Magic Wand normally limits the selection to only include the areas of
  208.     the image that are touching and are of a similar enough color. It is
  209.     possible, however, to make a selection based only on color, ignoring all 
  210.     boundaries and requirements for contiguity. This can be accomplished by
  211.     simply holding Shift while performing any of the other Magic Wand tasks
  212.     (including selection subtraction and extension).</p>

  228.                         then holding Shift while right clicking to
  229.                         exclude all black areas of the image.

  231.                         deselected.
