/**
 * pika_image_select_color:
 * @image: The affected image.
 * @operation: The selection operation.
 * @drawable: The affected drawable.
 * @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:
 * pika_context_set_antialias(), pika_context_set_feather(),
 * pika_context_set_feather_radius(), pika_context_set_sample_merged(),
 * pika_context_set_sample_criterion(),
 * pika_context_set_sample_threshold(),
 * pika_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

 * coordinates.
 *
 * 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:
 * pika_context_set_antialias(), pika_context_set_feather(),
 * pika_context_set_feather_radius(), pika_context_set_sample_merged(),
 * pika_context_set_sample_criterion(),
 * pika_context_set_sample_threshold(),
 * pika_context_set_sample_transparent(),
 * pika_context_set_diagonal_neighbors().
 *
 * 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.
