Signature

Herror T_query_all_colors(const Htuple WindowHandle, Htuple* Colors)

void QueryAllColors(const HTuple& WindowHandle, HTuple* Colors)

HTuple HWindow::QueryAllColors() const

static void HOperatorSet.QueryAllColors(HTuple windowHandle, out HTuple colors)

def query_all_colors(window_handle: HHandle) -> Sequence[str]

Description

query_all_colorsquery_all_colorsQueryAllColorsQueryAllColorsquery_all_colors returns the names of all colors that are known to HALCON. That doesn't mean that these colors are available for specific screens. On some screens there may only be a subset of colors available (see query_colorquery_colorQueryColorQueryColorquery_color). The HALCON colors are used to display regions (disp_regiondisp_regionDispRegionDispRegiondisp_region, disp_polygondisp_polygonDispPolygonDispPolygondisp_polygon, disp_circledisp_circleDispCircleDispCircledisp_circle, etc.). They can be defined with set_colorset_colorSetColorSetColorset_color.
