<p>
This tool determines the color at the specified coordinates. The
returned color is an RGB triplet even for grayscale and indexed
drawables. If the coordinates lie outside of the extents of the
specified drawable, then an error is returned. If the drawable has
an alpha channel, the algorithm examines the alpha value of the
drawable at the coordinates. If the alpha value is completely
transparent (0), then an error is returned. If the sample_merged
parameter is TRUE, the data of the composite image will be used
instead of that for the specified drawable. This is equivalent to
sampling for colors after merging all visible layers. In the case of
a merged sampling, the supplied drawable is ignored.
