Description🔗

query_all_colorsQueryAllColors 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_colorQueryColor). The HALCON colors are used to display regions (disp_regionDispRegion, disp_polygonDispPolygon, disp_circleDispCircle, etc.). They can be defined with set_colorSetColor.
