Description
query_all_colorsquery_all_colorsQueryAllColorsQueryAllColorsQueryAllColorsquery_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_colorQueryColorQueryColorQueryColorquery_color). The HALCON colors
are used to display regions (disp_regiondisp_regionDispRegionDispRegionDispRegiondisp_region,
disp_polygondisp_polygonDispPolygonDispPolygonDispPolygondisp_polygon, disp_circledisp_circleDispCircleDispCircleDispCircledisp_circle, etc.). They can
be defined with set_colorset_colorSetColorSetColorSetColorset_color.
