dev_set_lut — Set “look-up-table” (lut).
dev_set_lut( : : LutName : )
dev_set_lut sets the look-up-table of the active graphics window. A look-up-table defines the transformation of a “gray value” from an one-channel-image into a gray value or color on the screen. query_lut lists the names of all look-up-tables.
For more information see the description of the operator set_lut. However, in contrast to that operator the new look-up-table is also used for all new graphics windows that are opened afterwards.
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.
