Signature
Description
query_all_colorsquery_all_colorsQueryAllColorsQueryAllColorsQueryAllColors 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_colorQueryColorQueryColorQueryColor). The HALCON colors
are used to display regions (disp_regiondisp_regionDispRegionDispRegionDispRegion,
disp_polygondisp_polygonDispPolygonDispPolygonDispPolygon, disp_circledisp_circleDispCircleDispCircleDispCircle, etc.). They can
be defined with set_colorset_colorSetColorSetColorSetColor.
