VARIANT HWindowX.GetRgb(
[out] VARIANT* Green, [out] VARIANT* Blue)

static void HOperatorSet.GetRgb(HTuple windowHandle, out HTuple red, out HTuple green, out HTuple blue)

void HWindow.GetRgb(out HTuple red, out HTuple green, out HTuple blue)

Description

get_rgbget_rgbget_rgbGetRgbGetRgb returns the output colors or gray values, respectively, for the output window. They are defined by the three color components red, green and blue.
