* @color: The color to select.
*
* Create a selection by selecting all pixels (in the specified
* drawable) with the same (or similar) color to that specified.
*
* 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:
* gimp_context_set_antialias(), gimp_context_set_feather(),
* gimp_context_set_feather_radius(), gimp_context_set_sample_merged(),
* gimp_context_set_sample_criterion(),
* gimp_context_set_sample_threshold(),
* gimp_context_set_sample_transparent().
*
* In the case of a merged sampling, the supplied drawable is ignored.
*
* Returns: TRUE on success.

* Create a selection by selecting all pixels around specified

*
* 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.
*

* gimp_context_set_antialias(), gimp_context_set_feather(),

*
* In the case of a merged sampling, the supplied drawable is ignored.
* If the sample is merged, the specified coordinates are relative to
* the image origin; otherwise, they are relative to the drawable's
* origin.
