The Select by Color tool is designed to select areas of an image
50
based on color similarity. It works a lot like the Fuzzy Select
51
tool ("Magic Wand"). The main difference between them is that the
52
Magic Wand selects <span class="emphasis"><em>contiguous</em></span> regions, with
53
all parts connected to the starting point by paths containing no
54
large gaps; while the Select by Color tool selects all pixels that
55
are sufficiently similar in color to the pixel you click on,
56
regardless of where they are located. Also, clicking and dragging
57
in the image has no effect on the Select by Color tool.

The Magic Wand Tool can be activated from an image
70
<span class="guimenu">Tools</span>-><span class="guisubmenu">Selection Tools</span>-><span class="guimenuitem">Select by Color</span>;
71
from the Toolbox by clicking on the tool icon

<span class="guiicon">
73
<span class="inlinemediaobject"><img src="../images/toolbox/selbycolor.png" /></span>
75
or from the keyboard using the shortcut <span><b class="keycap">O</b></span> (note
76
that this is a capitalized letter O, not the number 0).

The select by color tool does not have any special key modifiers,

only the ones that affect all selection tools in the same way.

See <a href="ch03s02.html#gimp-tool-select" title="2.1. Common Features">Selection Tools</a> for
124
help with options that are common to all these tools. Only
125
options that are specific to the Select by Color tool are

explained here. Note that they are the same options as the

These options affect the way the Magic Wand expands the
141
selection out from the initial point.

<div class="itemizedlist">
146
<p><b>Select Transparent Areas. </b>
147
This option gives the Magic Wand the ability to select
148
areas that are completely transparent. If this option
149
is not checked, transparent areas will never be
150
included in the selection.
154
<p><b>Sample Merged. </b>
155
This option becomes relevant when you have several
156
layers in your image, and the active layer is either
157
semi-transparent or is set to another Layer Mode than
158
Normal. If this is the case, the colors present in the
159
layer will be different from the colors in the
160
composite image. If the "Sample Merged" option is
161
unchecked, the wand will only react to the color in
162
the active layer when it creates a selection. If it is
163
checked it will react to the composite color of all
164
visible layers. For further information, see the
165
glossary entry <a href="go01.html#glossary-samplemerge">Sample Merged</a>.
169
<p><b>Threshold. </b>
170
This slider determines the range of colors that will
171
be selected: the higher the threshold, the larger the
