Create a selection by selecting all pixels (in the specified
drawable) with the same (or similar) color to that specified.
</p>
<p>
This tool creates a selection over the specified image. A by-color
selection is determined by the supplied color under the constraints
of the current context settings. Essentially, all pixels (in the
drawable) that have color sufficiently close to the specified color
(as determined by the threshold and criterion context values) are
included in the selection. To select transparent regions, the color
specified must also have minimum alpha. This procedure is affected
by the following context setters: <a class="link" href="libgimp-gimpcontext.html#gimp-context-set-antialias" title="gimp_context_set_antialias ()"><code class="function">gimp_context_set_antialias()</code></a>,

Create a selection by selecting all pixels around specified
coordinates with the same (or similar) color to that at the
coordinates.
</p>
<p>
This tool creates a contiguous selection over the specified image. A
contiguous color selection is determined by a seed fill under the
constraints of the current context settings. Essentially, the color
at the specified coordinates (in the drawable) is measured and the
selection expands outwards from that point to any adjacent pixels
which are not significantly different (as determined by the
threshold and criterion context settings). This process continues
until no more expansion is possible. If antialiasing is turned on,
the final selection mask will contain intermediate values based on
close misses to the threshold bar at pixels along the seed fill
boundary. This procedure is affected by the following context
setters: <a class="link" href="libgimp-gimpcontext.html#gimp-context-set-antialias" title="gimp_context_set_antialias ()"><code class="function">gimp_context_set_antialias()</code></a>, <a class="link" href="libgimp-gimpcontext.html#gimp-context-set-feather" title="gimp_context_set_feather ()"><code class="function">gimp_context_set_feather()</code></a>,

the specified coordinates are relative to the image origin;

Create a polygonal selection over the specified image.
</p>
<p>
This tool creates a polygonal selection over the specified image.
The polygonal region can be either added to, subtracted from, or
replace the contents of the previous selection mask. The polygon is
specified through an array of floating point numbers and its length.
The length of array must be 2n, where n is the number of points.
Each point is defined by 2 floating point values which correspond to
the x and y coordinates. If the final point does not connect to the
starting point, a connecting segment is automatically added. This
procedure is affected by the following context setters:
