Description

dev_set_colordev_set_colorDevSetColorDevSetColorDevSetColordev_set_color defines the color(s) that are used to display regions, XLDs, and other geometrical objects in the graphics windows. The available colors can be queried with the operator query_colorquery_colorQueryColorQueryColorQueryColorquery_color. In addition, the ColorNameColorNameColorNameColorNamecolorNamecolor_name may be specified as hexadecimal RGB triplet or RGBA quadruplet in the form '#rrggbb'"#rrggbb""#rrggbb""#rrggbb""#rrggbb""#rrggbb" and '#rrggbbaa'"#rrggbbaa""#rrggbbaa""#rrggbbaa""#rrggbbaa""#rrggbbaa". 'rr', 'gg', 'bb', and 'aa' are hexadecimal numbers between '00' and 'ff', respectively. 'aa' denotes the alpha value of a color and can be used to display transparent regions.

For more information see the description of the operator set_colorset_colorSetColorSetColorSetColorset_color. 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_colordev_set_colorDevSetColorDevSetColorDevSetColordev_set_color or dev_set_coloreddev_set_coloredDevSetColoredDevSetColoredDevSetColoreddev_set_colored is called or until the color settings are modified interactively.

Attention

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.
