Description

The interface used for quering color sensors.

Details

Lock ()

Lock ()

Locks the sensor for use by an application.

If the current holder of the lock quits without calling Unlock then it is automatically removed.


Unlock ()

Unlock ()

Unlocks the sensor for use by other applications.


GetSample ()

GetSample (in's'capability,
out'd'sample_x,
out'd'sample_y,
out'd'sample_z)

Gets a color sample using the sensor.

capability:

The capability we are using, e.g. crt, ambient, lcd, led or projector.

sample_x:

The X value, or -1.0 for an error.

For the capability of ambient this is the brightness in Lux.

sample_y:

The Y value, or -1.0 for an error.

sample_z:

The Z value, or -1.0 for an error.


SetOptions ()

SetOptions (in'a{sv}'values)

Sets one or multiple options on the sensor.

values:

A dictionary of property keys and values, e.g. remote-profile-hash = deadbeef.

Signal Details

The ButtonPressed signal

ButtonPressed ()

A button on the sensor has been pressed.

Property Details

The "SensorId" property

'SensorId'read's'

The sensor id string.


The "Kind" property

'Kind'read's'

The kind of the sensor, e.g. colormunki


The "State" property

'State'read's'

The state of the sensor, e.g. starting, idle or measuring.


The "Mode" property

'Mode'read's'

The operating mode of the sensor, e.g. ambient, printer or unknown.

On some devices, a sensor has to be set to a specific position before a reading can be taken. This property should be set to the current device mode.


The "Serial" property

'Serial'read's'

The sensor serial number, e.g. 012345678a.


The "Model" property

'Model'read's'

The sensor model, e.g. ColorMunki.


The "Vendor" property

'Vendor'read's'

The sensor vendor, e.g. XRite.


The "Native" property

'Native'read'b'

If the sensor is supported with a native driver, which does not require additional tools such as argyllcms.


The "Embedded" property

'Embedded'read'b'

If the sensor is embedded into the laptop hardware, for example the W700 device from Lenovo.

If this property is set then the calibration process should show the color patch fullscreen and should emit an audible alert when completed.


The "Locked" property

'Locked'read'b'

If the sensor is locked for use by colord.


The "Capabilities" property

'Capabilities'read'as'

The capabilities of the sensor, e.g ['display', 'printer', 'projector', 'spot'].


The "Options" property

'Options'read'a{sv}'

The options currently set on the sensor.

This is a dictionary of property keys and values, e.g. remote-profile-hash = deadbeef.


The "Metadata" property

'Metadata'read'a{ss}'

The metadata for the sensor, which may include optional keys like AttachImage.
