message	the log message text.

Member Function Documentation

◆ clearCalibrationFileSourceDirectory()

static OTC_SDK_API void optris::Sdk::clearCalibrationFileSourceDirectory ( )

static

Clears a previously set source directory for calibration files.

When cleared, the SDK will skip the CalibrationFileSource::Filesystem option when acquiring calibration files.

◆ clearCustomDataDirectory()

static OTC_SDK_API void optris::Sdk::clearCustomDataDirectory ( )

static

Clears a previously set custom data directory for the SDK.

Once cleared the SDK reverts to the default user data directory:

Linux ~/.config/optris/
Windows <User AppData>/Roaming/Imager/

Exceptions

SDKException if there is an active device connection or if the default user data directory path could not be determined.

◆ configureLogger()

static OTC_SDK_API void optris::Sdk::configureLogger	(	Verbosity	logScreen,
		Verbosity	logFile,
		std::string	logFilenamePrefix = "" )

static

Configures the SDK internal logger.

If you change the logFilenamePrefix from the one used in Sdk::init() or in a previous call to Sdk::configure(), the current log file will be closed and new one will be created.

Parameters

[in]	logScreen	defines the minimum verbosity level of log messages displayed on the standard output and error.
[in]	logFile	defines the minimum verbosity level of log messages out to the logfile.
[in]	logFilenamePrefix	for the log file `<logFilenamePrefix>_<YYYY_MM_DDThh-mm-ss>.log`. If empty, it defaults to "OtcSDK".

◆ getPaletteColors()

static OTC_SDK_API std::vector< std::array< uint8_t, 3 > > optris::Sdk::getPaletteColors ( const std::string & name )

static

Returns the 240 RGB color entries of the named palette.

Each entry is an array of three bytes: { R, G, B }.

Parameters

[in] name palette name (case-sensitive).

Returns: vector of 240 RGB triples.

Exceptions

SDKException if the palette is not found.

◆ getPaletteNames()

static OTC_SDK_API std::vector< std::string > optris::Sdk::getPaletteNames ( )

static

Returns the names of all currently loaded palettes in sorted order.

Returns: sorted list of palette name strings.

◆ getVersionInfo()

static OTC_SDK_API VersionInfo optris::Sdk::getVersionInfo ( )

static

Returns an object holding version and build information about the SDK.

Returns: object holding version and build information about the SDK.

◆ init()

static OTC_SDK_API void optris::Sdk::init	(	Verbosity	logScreen,
		Verbosity	logFile,
		std::string	logFilenamePrefix = "",
		std::string	customDataDirectory = "" )

static

Initializes the SDK.

It sets the verbosity levels of the internal logger of the SDK, starts the EnumerationManager in a dedicated thread to monitor the availability of devices, and loads color palettes from the SDK, working, and user palette directories.

Parameters

[in]	logScreen	defines the minimum verbosity level of log messages displayed on the standard output and error.
[in]	logFile	defines the minimum verbosity level of log messages out to the logfile.
[in]	logFilenamePrefix	for the log file `<logFilenamePrefix>_<YYYY_MM_DDThh-mm-ss>.log`. If empty, it defaults to "OtcSDK".
[in]	customDataDirectory	for the SDK to use. An empty string will have no effect. The SDK requires read and write access to this directory. For detail on how specify it see Sdk::setCustomDataDirectory().

◆ loadPalettes() [1/2]

static OTC_SDK_API void optris::Sdk::loadPalettes ( )

static

Loads palettes from the SDK and user palette directories.

Scans the SDK data directory first, then the user data directory so that user-supplied palettes with the same name override the built-in ones. Missing directories are silently skipped.

This method is idempotent — calling it more than once reloads all palettes from disk, replacing any previously registered entries.

◆ loadPalettes() [2/2]

static OTC_SDK_API void optris::Sdk::loadPalettes ( const std::string & directory )

static

Loads palettes from a custom directory.

Adds or overwrites palette entries in the registry without clearing previously loaded palettes.

When specifying the directory path the following symbols/variables are supported:

~, %USERPROFILE% refer to ~/ on Linux and <User Home>/ on Windows.
%APPDATA% refers to ~/.config/ on Linux and <User AppData>/Roaming/ on Windows.

Relative paths are not supported. You can either use / as system independet directory separator or utilize system dependent ones like / for Linux and \ on Windows.

Parameters

[in] directory path to scan for .csv palette files.

Exceptions

SDKException if directory does not exist or is not a directory.

◆ registerPalette()

static OTC_SDK_API void optris::Sdk::registerPalette	(	const std::string &	name,
		const std::vector< std::array< uint8_t, 3 > > &	colors )

static

Registers a palette at runtime without persisting it to disk.

An existing palette with the same name is overwritten.

Parameters

[in]	name	unique palette name.
[in]	colors	exactly 240 RGB triples `{ R, G, B }`.

Exceptions

SDKException if colors does not contain exactly 240 entries.

◆ savePalette()

static OTC_SDK_API void optris::Sdk::savePalette ( const std::string & name )

static

Saves a registered palette as a CSV file in the user palette directory.

The output filename is <name>.csv. The user palette directory is created automatically if it does not exist.

Parameters

[in] name palette name to save (case-sensitive).

Exceptions

SDKException if the palette is not found or the file cannot be written.

◆ setCalibrationFileSourceDirectory()

static OTC_SDK_API void optris::Sdk::setCalibrationFileSourceDirectory ( const std::string & sourceDirectory )

static

Sets the source directory from which calibration files can be copied.

When specifying the directory path the following symbols/variables are supported:

~, %USERPROFILE% refer to ~/ on Linux and <User Home>/ on Windows.
%APPDATA% refers to ~/.config/ on Linux and <User AppData>/Roaming/ on Windows.

Relative paths are not supported. You can either use / as system independet directory separator or utilize system dependent ones like / for Linux and \ on Windows.

Parameters

[in] sourceDirectory from which calibration files can be copied. An empty string will have no effect.

Exceptions

SDKException if the given path does not exist or is not a directory.

◆ setCalibrationFileSources()

static OTC_SDK_API bool optris::Sdk::setCalibrationFileSources	(	CalibrationFileSource	first,
		CalibrationFileSource	second,
		CalibrationFileSource	third )

static

Sets the priority of the calibration file sources.

The priority of the sources needs to be set prior to connecting to a device. If you want to use less than three potential calibration file source, set the one you do not require to Empty. The different sources have individual requirements for them to work:

Device. Not all types of Optris cameras have their calibration files stored on-device.
Filesystem. The source directory should be accessible and the SDK should have the rights to copy the calibration files from it to their target destination. The source directory needs to be specified via the Sdk::setCalibrationFileSourceDirectory() method.
Internet. Access to the internet is required.

Note: The SDK does not yet feature the ability to download the calibration from the device.

Parameters

[in]	first	source with the highest priority.
[in]	second	source with a medium priority.
[in]	third	source with the lowest priority.

Returns: true, if priority was successfully set. False, otherwise.

◆ setCustomDataDirectory()

static OTC_SDK_API void optris::Sdk::setCustomDataDirectory ( const std::string & customDataDirectory )

static

Sets a custom data directory for the SDK to use.

Attention: A custom data directory can only be set when there are no active device connections.

If the given directory does not exist, the SDK will try to create it (recursively).

When specifying the directory path the following symbols/variables are supported:

~, %USERPROFILE% refer to ~/ on Linux and <User Home>/ on Windows.
%APPDATA% refers to ~/.config/ on Linux and <User AppData>/Roaming/ on Windows.

Relative paths are not supported. You can either use / as system independet directory separator or utilize system dependent ones like / for Linux and \ on Windows.

Parameters

[in] customDataDirectory for the SDK to use. An empty string will have no effect. The SDK requires read and write permission to this directory.

Exceptions

SDKException

if

there is an active device connection.
the given path is not a directory.
the SDK can not access the directory
the SDK failed to create the directory.

◆ setLogCallback()

static OTC_SDK_API void optris::Sdk::setLogCallback	(	LogCallback	callback,
		bool	exclusive = false )

static

Sets a callback that receives SDK log messages.

Parameters

[in]	callback	function pointer to invoke on each log message, or nullptr to remove.
[in]	exclusive	when true, disables file and screen output while the callback is active.
