## Detailed Description

Interface class for the Softcopy Presentation State viewer.

This class manages the database facilities, allows to start and stop network transactions and gives access to images and presentation states.

## Constructor & Destructor Documentation

## ◆ DVInterface()

DVInterface::DVInterface | ( | const char * | config_file = NULL,
|  | OFBool | useLog = OFFalse )

constructor.

Parameters

  config_file | filename (path) of the config file to be used by the interface object. The caller should make sure that the config file really exists because the constructor cannot return an error status. If a non-existing filename (or NULL) is passed, an empty configuration file is assumed.
  useLog | (optional) flag specifying whether a general log file should be used (config entry GENERAL\APPLICATION\LOGFILE).

Referenced by DVInterface(), and operator=().

## Member Function Documentation

## ◆ addImageReferenceToPState()

OFCondition DVInterface::addImageReferenceToPState | ( | const char * | studyUID,
|  | const char * | seriesUID,

|  | const char * | instanceUID )

adds an existing DICOM image (should be Hardcopy Grayscale) that is already present in the image database to the current print image queue without rendering it again.

The "requested image size" option is not used - the bitmap is treated as if the presentation mode was "SCALE TO FIT".

Parameters

The configuration file which is required for the query/retrieve process will be created automatically from the 'global' configuration file each time this method is called, unless this automatic creation is disabled (entry: [QUERYRETIUEVE] AutoCreateConfigFile = false). Attention: Successful return of this method is no guarantee that the query/retrieve server has successfully started, because certain errors (i.e. incorrect settings in the config file) will only be noted in the query/retrieve process when running. On Unix platform, successful return of this method means that the fork() used to start the receiver was successful. On Win32 platforms, it means that the CreateProcess() call was successful.

Returns
  EC_Normal if the query/retrieve process could be started, an error code otherwise.

## ◆ startReceiver()

OFCondition DVInterface::startReceiver | ( |  | ) |

starts the network receiver processes (Storage Service Class SCPs).

The receiver processes will wait for incoming DICOM associations, receive images and presentation states. Data will be stored in file and registered in the database index file. Attention: Successful return of this method is no guarantee that the network receiver has successfully started, because certain errors (i.e. incorrect settings in the config file) will only be noted in the network receiver process when running. On Unix platform, successful return of this method means that the fork() used to start the receiver was successful. On Win32 platforms, it means that the CreateProcess() call was successful.

Returns
  EC_Normal if the receiver processes could be started, an error code otherwise.

## ◆ terminatePrintServer()

OFCondition DVInterface::terminatePrintServer | ( |  | ) |

terminates the print server process (Basic Grayscale Print Management SCP).

This method attempts to terminate the print server process by requesting a DICOM association with it and delivering a special "shutdown" command. If for some reason the print server cannot be found (i.e. because it has terminated abnormally), a TCP/IP timeout (several seconds) may occur before this method returns.

Returns
  EC_Normal if the server process could be terminated, an error code otherwise.

## ◆ terminatePrintSpooler()

OFCondition DVInterface::terminatePrintSpooler | ( |  | ) |

## ◆ terminateQueryRetrieveServer()

OFCondition DVInterface::terminateQueryRetrieveServer | ( |  | ) |

terminates the query/retrieve server process (Query/Retrieve Service Class SCP).

This method attempts to terminate the query/retrieve process by requesting a DICOM association with it and delivering a special "shutdown" command. If for some reason the query/retrieve server cannot be found (i.e. because it has terminated abnormally), a TCP/IP timeout (several seconds) may occur before this method returns.

Returns
  EC_Normal if the query/retrieve process could be terminated, an error code otherwise.

## ◆ terminateReceiver()

OFCondition DVInterface::terminateReceiver | ( |  | ) |

terminates the network receiver process (Storage Service Class SCP).

This method attempts to terminate the network receiver process by requesting a DICOM association with it and delivering a special "shutdown" command. If for some reason the network receiver cannot be found (i.e. because it has terminated abnormally), a TCP/IP timeout (several seconds) may occur before this method returns.

## ◆ verifyAndSignStructuredReport()

OFCondition DVInterface::verifyAndSignStructuredReport | ( | const char * | userID,
|  | const char * | passwd,
|  | DVPSVerifyAndSignMode | mode )

verifies and digitally signs the current structured report.

If the user ID is known (i.e. specified in the configuration file) the current structured report is verified (a verifying observer is added). If the 'mode' parameter is set accordingly and the password is correct (see verifyUserPassword) the report is also digitally signed. Please note that a document can be verified/signed more than once, but only completed documents can be verified. After signing the report no modifications should be performed before the object is stored in the database or a file. Otherwise the digital signature would be corrupted. Therefore, the SOP instance UID should be generated before calling this method.

Remarks
  this method only has full functionality if DCMTK is compiled with OpenSSL support enabled. If not, only mode DVPSY_verify (verification) is available and an error is returned for any other mode.

Parameters

  userID | symbolic user ID for given user, as returned by DVConfiguration::getUserID()
  passwd | for user as entered in some GUI control
  mode | flag specifying whether to verify only, verify and sign or verify and sign and finalize the document. The difference between the second and the third mode is that "finalize" always signs the entire document whereas the other mode only signs the marked items (if any, all items otherwise) and leaves out certain header attributes (e.g. the SOP instance UID and the verifying observer sequence).

Returns
  status, EC_Normal if successful, an error code otherwise.

## ◆ verifyUserPassword()

OFBool DVInterface::verifyUserPassword | ( | const char * | userID,
|  | const char * | passwd )

verifies the given password for the given user ID.

This method tries to load and decrypt the private key for the given user with the given password. If this fails, the password verification fails, otherwise the password verification succeeds.

Remarks
  this method is only functional if DCMTK is compiled with OpenSSL support enabled. Otherwise it always returns false.

Parameters

  userID | symbolic user ID for given user, as returned by DVConfiguration::getUserID()
  passwd | for user as entered in some GUI control

Returns
  true if password verification succeeds, false otherwise.
