dev_set_lutdev_set_lutDevSetLutDevSetLut (Operator)

Name

dev_set_lutdev_set_lutDevSetLutDevSetLut — Set “look-up-table” (lut).

Signature

dev_set_lut( : : LutName : )

Herror dev_set_lut(const char* LutName)

Herror T_dev_set_lut(const Htuple LutName)

void DevSetLut(const HTuple& LutName)

static void HWindow::DevSetLut(const HString& LutName)

static void HWindow::DevSetLut(const char* LutName)

static void HOperatorSet.DevSetLut(HTuple lutName)

static void HWindow.DevSetLut(string lutName)

Description

dev_set_lutdev_set_lutDevSetLutDevSetLutDevSetLut 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_lutQueryLutQueryLutQueryLut lists the names of all look-up-tables.

For more information see the description of the operator set_lutset_lutSetLutSetLutSetLut. 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.

Name of look-up-table, values of look-up-table (RGB) or file name.

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_lutDevSetLutDevSetLutDevSetLut returns 2 (H_MSG_TRUE). Otherwise an exception is raised and an error code returned.

Possible Successors
