Detailed Description

Color device meta data and profile handling.

Include the oyranos_devices.h header file to use the interfaces.

Devices are a special form of configurations. Their access is grouped for effective performance. Known devices are queried with oyDevicesGet(). oyConfigDomainList() provides a list of known device modules. A single device can be obtained by oyDeviceGet(). The device_type argument defaults to OY_TYPE_STD and can be omitted for this group. The device_class argument specifies a subgroup, e.g. "monitor".

All other functions return a handle to the device. With this handle it is possible to get informations (oyDeviceGetInfo()), query it's current, possibly remote profile (oyDeviceAskProfile2()) or typical used get a profile with fallbacks including the DB through (oyDeviceGetProfile()), set the profile persistent (oyDeviceSetProfile()) or query the persistent stored profile (oyDeviceProfileFromDB()).

Function Documentation

OYAPI int OYEXPORT oyDeviceAskProfile2 ( oyConfig_s device,
oyOptions_s options,
oyProfile_s **  profile 
)

ask for the device profile

Function oyDeviceAskProfile2 Ask for a profile associated with the device. A device capable to hold a profile. Only the held profile will be checked and returned. In case this profile is not found a "icc_profile" of oyVAL_STRUCT should be included.

The device might not be able to hold a profile, then just the DB profile will be returned from here without an issue. For interessted users, the source of the profile keeps transparent, as it can be checked if the device contains a "icc_profile" option which contains a oyProfile_s object.

Parameters
[in]devicethe device
[in]optionsadditional options
[out]profilethe device's ICC profile

OYAPI int OYEXPORT oyDeviceGetProfile ( oyConfig_s device,
oyOptions_s options,

order a device profile

Function oyDeviceGetProfile This function is designed to satisfy most users as it tries to deliver a profile all the time. Following code can almost allways expect some profile to go with. It tries hard to get a current profile or set the system up and retry or get at least one basic profile.

For a basic and thus weaker call to the device use oyDeviceAskProfile2() instead.

Parameters
devicethe device
optionsoptions passed to the backend
profilethe device's ICC profile
Returns
error

Function oyDeviceProfileFromDB The function asks the module for a detailed and possible expensive list of device information and tries to find a matching configuration in the DB. The device informations are the same as for saving to DB.

get similiar devices by a pattern from a list

Function oyDeviceSelectSimiliar The function takes a device and tries to find exact matches, which can be considered as belonging to the same device. The comparision can be influenced by the flags. The option "profile_name" is ignored during the comparision.

Parameters
[in]patternPass a device used as reference. String options of this object are compared to the objects in the heap argument depending on the flags argument. "profile_name" and other options from heap objects are ignored.
[in]heapa list of device objects
[in]flags- 0 yields exact match

Function oyDeviceSetProfile The function will lookup the device in the Oyranos device database and stores the given profile there.

To set a new profile und update the device please call the following sequence:

// store new settings in the Oyranos data base
oyDeviceSetProfile( device, profile );
// remove any device entries
oyDeviceUnset( device );
// update the device from the newly added Oyranos data base settings

search a calibration state in the taxi DB for a device

Function oyDevicesFromTaxiDB oyDevicesFromTaxiDB() needs a device containing the calibration state and gives you a list of found devices in Taxi DB. You can extract the device ID inside the "TAXI_id" string from the returned devices "db" options sets. Typical you want one entry in the profiles list assigned with that device. oyProfile_FromTaxiDB() can be used to download that and oyProfile_Install() helps installing it, while doing some consistency checks.
