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.",
