Constructor & Destructor Documentation

◆ VariableLineScanCameraDetectorMap()

Isis::VariableLineScanCameraDetectorMap::VariableLineScanCameraDetectorMap ( Camera parent,
std::vector< LineRateChange > &  lineRates 
)

Constructs a VariableLineScanCameraDetectorMap.

Parameters
parentThe camera
p_lineRatesThis should be a vector with an entry for every scan rate change in it. The pair consists of the line number and ET of the changed time; the first entry should be line 1 and the last entry should be one line past the end of the image. See HrscCamera for an example.

◆ ~VariableLineScanCameraDetectorMap()

Isis::VariableLineScanCameraDetectorMap::~VariableLineScanCameraDetectorMap ( )
virtual

Destructor.

◆ exposureDuration()

double Isis::VariableLineScanCameraDetectorMap::exposureDuration ( const double  sample,
const double  line,
const int  band 
) const
virtual

This virtual method is for returning the exposure duration of a given pixel.

For a variable line scan camera, the exposure duration is assumed to be the line scan rate for the given line. Note, this may not be the actual exposure duration. The line scan rate is the time from the beginning of one line to the beginning of the next. The exposure duration is the time from the beginning of a line to the end of that line. So, if the end of a line is not the beginning of the next line, these two values will not be the same.

Parameters
sampleThe sample of the desired pixel.
lineThe line of the desired pixel.
bandThe band of the desired pixel.
Returns
double The exposure duration for the desired pixel in seconds.
Exceptions
IException::Programmer"line was not found in the line scan rate table."

How do we get the actual exposure duration?

Reimplemented from Isis::LineScanCameraDetectorMap.

◆ LineRate()

double Isis::LineScanCameraDetectorMap::LineRate ( ) const
virtualinherited

Access the time, in seconds, between scan lines.

Returns
Line rate.

Reimplemented from Isis::CameraDetectorMap.

◆ lineRate()

LineRateChange & Isis::VariableLineScanCameraDetectorMap::lineRate ( const double  line) const

Get the line rate information for a given line.

Parameters
lineThe line to find the line rate information for.
Returns
LineRateChange& The LineRateChange object that is used for time calculations with the input line.

◆ SetDetector()

bool Isis::VariableLineScanCameraDetectorMap::SetDetector ( const double  sample,

Compute parent position from a detector coordinate.

This method will compute a parent sample given a detector coordinate. The parent line will be computed using the the time in the parent camera

Parameters
sampleSample number in the detector
lineLine number in the detector
Returns
conversion successful

◆ SetLineRate()

void Isis::LineScanCameraDetectorMap::SetLineRate ( const double  lineRate)
inherited

Reset the line rate.

Use this method to reset the time between lines. Usually this will not need to be done unless the rate changes between bands.

Parameters
lineRatethe time in seconds between lines

◆ SetParent() [1/2]

bool Isis::VariableLineScanCameraDetectorMap::SetParent ( const double  sample,
const double  line 
)
virtual

Compute detector position from a parent image coordinate.

This method will compute the detector position from the parent line/sample coordinate. The parent line will be used to set the appropriate time in the parent camera.

Parameters
sampleSample number in the parent image
lineLine number in the parent image
Returns
conversion successful

Reimplemented from Isis::LineScanCameraDetectorMap.

◆ SetParent() [2/2]

bool Isis::VariableLineScanCameraDetectorMap::SetParent ( const double  sample,
const double  line,
const double  deltaT 
)
virtual

Compute detector position from a parent image coordinate.

This method will compute the detector position from the parent line/sample coordinate. The parent line will be used to set the appropriate time in the parent camera.

Parameters
sampleSample number in the parent image
lineLine number in the parent image
deltaToffset in seconds from center exposure time
Returns
bool conversion successful

◆ SetStartingDetectorLine()

void Isis::CameraDetectorMap::SetStartingDetectorLine ( const double  line)
inlineinherited

Set the starting detector line.

Use this method to specify the starting detector that represents the first image line in the cube. If not set the default is 1.

Parameters
lineStarting detector line

◆ SetStartingDetectorSample()

◆ SetStartTime()

void Isis::LineScanCameraDetectorMap::SetStartTime ( const double  etStart)
inherited

Reset the starting ephemeris time.

Use this method to reset the starting time of the top edge of the first line in the parent image. That is the time, prior to cropping, scaling, or padding. Usually this will not need to be done unless the time changes between bands.

Parameters
etStartstarting ephemeris time in seconds

◆ StartTime()

double Isis::LineScanCameraDetectorMap::StartTime ( ) const
inherited

Access the starting time at the top edge of the first line in the parent image.

Returns
The start ephemeris time for the image.
