get_hsi — Get the HSI coding of the current color.
get_hsi returns the output color or gray values, respectively, for the window, described in Hue, Saturation and Intensity. get_hsi corresponds to the operator get_pixel but returns the entries of the color lookup table instead of its indices. The values returned by get_hsi can be set with set_hsi.
The values returned by get_hsi may be inaccurate due to rounding errors. They do not necessarily match the values set with set_hsi exactly (colors are stored in RGB internally).
Hue (color value) of the current color.
Saturation of the current color.
Intensity of the current color.
get_hsi returns 2 (H_MSG_TRUE), if the window is valid. Otherwise an exception is raised.
