dev_set_colored — Set multiple output colors.
dev_set_colored( : : NumColors : )
dev_set_colored allows to display tuples of regions, XLDs, and other geometrical objects in the graphics windows in different colors using a set of NumColors predefined colors. Valid values for NumColors can be queried with the operator query_colored.
For more information see the description of the operator set_colored. However, in contrast to that operator the color setting is also used for all new graphics windows that are opened afterwards.
These color settings remain valid until dev_set_color or dev_set_colored is called or until the color setting are modified interactively.
Using the code export feature of HDevelop, the code that is generated for this operator may have a different behavior than the related HALCON operator. For a detailed description of the code export of HDevelop graphics operators into the different programming languages see in the “HDevelop User's Guide” the chapter Code Export -> General Aspects of Code Generation -> Graphics Windows.
