Description

dev_set_lutdev_set_lutDevSetLutdev_set_lutDevSetLutDevSetLut 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_lutquery_lutQueryLutquery_lutQueryLutQueryLut lists the names of all look-up-tables.

For more information see the description of the operator set_lutset_lutSetLutset_lutSetLutSetLut. However, in contrast to that operator the new look-up-table is also used for all new graphics windows that are opened afterwards.

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.

File extension: .lut

Example (HDevelop)

read_image(Image,'mreut')
dev_set_lut('inverse')
* For true color only:
dev_display(Image)

Result

If the values of the specified parameters are correct, dev_set_lutdev_set_lutDevSetLutdev_set_lutDevSetLutDevSetLut returns 2 (H_MSG_TRUE). Otherwise an exception is raised and an error code returned.

Possible Successors
