Definition at line 4512 of file capture.cpp.

QString Ekos::Capture::getSequenceQueueStatus

(

)

DBUS interface function.

Returns the overall sequence queue status. If there are no jobs pending, it returns "Invalid". If all jobs are idle, it returns "Idle". If all jobs are complete, it returns "Complete". If one or more jobs are aborted it returns "Aborted" unless it was temporarily aborted due to guiding deviations, then it would return "Suspended". If one or more jobs have errors, it returns "Error". If any jobs is under progress, returns "Running".

Definition at line 4670 of file capture.cpp.

bool Ekos::Capture::hasCoolerControl

(

)

DBUS interface function.

Does the CCD has a cooler control (On/Off) ?

Definition at line 5160 of file capture.cpp.

void Ekos::Capture::ignoreSequenceHistory

(

)

DBUS interface function.

Jobs will NOT be checked for progress against the file system and will be always assumed as new jobs.

Definition at line 4312 of file capture.cpp.

bool Ekos::Capture::loadSequenceQueue

(

const QString &

fileURL

)

DBUS interface function.

Loads the Ekos Sequence Queue file in the Sequence Queue. Jobs are appended to existing jobs.

Parameters

fileURL

full URL of the filename

Definition at line 3747 of file capture.cpp.

Q_SCRIPTABLE QStringList Ekos::Capture::logText ( )

inline

Definition at line 284 of file capture.h.

bool Ekos::Capture::setCamera

(

const QString &

device

)

DBUS interface function.

select the CCD device from the available CCD drivers.

Parameters

device

The CCD device name

Definition at line 764 of file capture.cpp.

void Ekos::Capture::setCapturedFramesMap	(	const QString &	signature,
		int	count
	)

DBUS interface function.

Set count of already completed frames. This is required when we have identical external jobs with identical paths, but we need to continue where we left off. For example, if we have 3 identical jobs, each capturing 5 images. Let's suppose 9 images were captured before. If the count for this signature is set to 1, then we continue to capture frame #2 even though the number of completed images is already larger than required count (5). It is mostly used in conjunction with Ekos Scheduler.

Definition at line 6493 of file capture.cpp.

bool Ekos::Capture::setCoolerControl

(

filter

)

select the filter name from the available filters in case a filter device is active.

Parameters

filter

The filter name

Definition at line 1346 of file capture.cpp.

bool Ekos::Capture::setFilterWheel

(

const QString &

device

)

DBUS interface function.

select the filter device from the available filter drivers. The filter device can be the same as the CCD driver if the filter functionality was embedded within the driver.

Parameters

device

The filter device name

Definition at line 1312 of file capture.cpp.

void Ekos::Capture::setInSequenceFocus	(	bool	enable,
		double	HFR
	)

DBUS interface function.

Enables or disables the in sequence focus and sets Half-Flux-Radius (HFR) limit.

Parameters

enable	If true, enable the in sequence auto focus check, otherwise, disable it.
HFR	if enable is true, it sets HFR in pixels. After each exposure, the HFR is re-measured and if it exceeds the specified value, an autofocus operation will be commanded.

Definition at line 4647 of file capture.cpp.

void Ekos::Capture::setMaximumGuidingDeviation	(	bool	enable,
		double	value
	)

DBUS interface function.

Enables or disables the maximum guiding deviation and sets its value.

Parameters

enable	If true, enable the guiding deviation check, otherwise, disable it.
value	if enable is true, it sets the maximum guiding deviation in arcsecs. If the value is exceeded, the capture operation is aborted until the value falls below the value threshold.

Definition at line 4640 of file capture.cpp.

Q_SCRIPTABLE Ekos::CaptureState Ekos::Capture::status ( )

inline

Definition at line 289 of file capture.h.

Public Slots

Q_SCRIPTABLE Q_NOREPLY void Ekos::Capture::abort ( )

inlineslot

DBUS interface function.

Aborts all jobs and mark current state as ABORTED. It simply calls stop(CAPTURE_ABORTED)

Definition at line 386 of file capture.h.

void Ekos::Capture::start ( )

slot

DBUS interface function.

Starts the sequence queue capture procedure sequentially by starting all jobs that are either Idle or Aborted in order.

Definition at line 516 of file capture.cpp.

void Ekos::Capture::stop ( CaptureState  targetState = CAPTURE_IDLE )

slot

DBUS interface function.

Stop all jobs and set current job status to aborted if abort is set to true, otherwise status is idle until sequence is resumed or restarted.

Parameters

targetState

status of the job after abortion

Definition at line 617 of file capture.cpp.

Q_SCRIPTABLE Q_NOREPLY void Ekos::Capture::suspend ( )

inlineslot

DBUS interface function.

Aborts all jobs and mark current state as SUSPENDED. It simply calls stop(CAPTURE_SUSPENDED) The only difference between SUSPENDED and ABORTED it that capture module can automatically resume a suspended state on its own without external trigger once the right conditions are met. When whatever reason caused the module to go into suspended state ceases to exist, the capture module automatically resumes. On the other hand, ABORTED state must be started via an external programmatic or user trigger (e.g. click the start button again).

Definition at line 398 of file capture.h.

void Ekos::Capture::toggleVideo ( bool  enabled )

slot

DBUS interface function.

Toggle video streaming if supported by the device.

Parameters

enabled

Set to true to start video streaming, false to stop it if active.

Definition at line 6158 of file capture.cpp.
