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 该算子
query_colored.
For more information see the description of 该算子 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.
