set_hsiset_hsiSetHsiset_hsiSetHsiSetHsi sets the region output color(s)/grayvalue(s) for the valid window. Colors are passed as HueHueHueHueHuehue, SaturationSaturationSaturationSaturationSaturationsaturation, and IntensityIntensityIntensityIntensityIntensityintensity. Transformation from HSI to RGB is done with:

The value range is clipped to 0 to 255.

If only one combination is passed, all output will take place in that color. If a tuple of colors is passed, the output color of regions and geometric objects is modulo to the number of colors. HALCON always begins output with the first color passed. Note, that the number of output colors depends on the number of objects that are displayed in one operator call. If only single objects are displayed, they always appear in the first color, even if the consist of more than one connected components.

Selected colors are used until the next call of set_colorset_colorSetColorset_colorSetColorSetColor,set_rgbset_rgbSetRgbset_rgbSetRgbSetRgb or set_grayset_graySetGrayset_graySetGraySetGray. Colors are relevant to windows, i.e. only the colors of the valid window can be set. Region output colors are used by operators like disp_regiondisp_regionDispRegiondisp_regionDispRegionDispRegion, disp_linedisp_lineDispLinedisp_lineDispLineDispLine, disp_rectangle1disp_rectangle1DispRectangle1disp_rectangle1DispRectangle1DispRectangle1, disp_rectangle2disp_rectangle2DispRectangle2disp_rectangle2DispRectangle2DispRectangle2, disp_arrowdisp_arrowDispArrowdisp_arrowDispArrowDispArrow, etc. It is also used by operators with gray value output in certain output modes (e.g. '3d_plot_lines','histogram', 'contourline', etc. See set_paintset_paintSetPaintset_paintSetPaintSetPaint).


The colors are internally stored as RGB triples. Some HSI triples can not be represented by a valid RGB triple (i.e. in the range 0..255). In this case the nearest color which can be represented is used instead.
