get_hsiT_get_hsiGetHsiGetHsiget_hsi — 获取当前颜色的 HSI（Hue，Saturation，Intensity）编码。

签名

get_hsi( : : WindowHandle : Hue, Saturation, Intensity)

描述

get_hsiget_hsiGetHsiGetHsiGetHsiget_hsi returns the output color or gray values, respectively, for the window, described in HueHueHueHuehuehue, SaturationSaturationSaturationSaturationsaturationsaturation and IntensityIntensityIntensityIntensityintensityintensity. The values returned by get_hsiget_hsiGetHsiGetHsiGetHsiget_hsi can be set with set_hsiset_hsiSetHsiSetHsiSetHsiset_hsi。

注意

The values returned by get_hsiget_hsiGetHsiGetHsiGetHsiget_hsi may be inaccurate due to rounding errors. They do not necessarily match the values set with set_hsiset_hsiSetHsiSetHsiSetHsiset_hsi exactly (colors are stored in RGB internally).
