## ◆ importFromSourceImage() [1/2]

virtual OFCondition EctEnhancedCT::importFromSourceImage | ( | const OFString & | filename,
|  | const OFBool | takeOverCharset = OFTrue )
| virtual

Import Patient, Study, and Frame of Reference level information from the given item.

The method does only import Frame of Reference if Frame of Reference UID is found in the image (and no error is reported if not). The reason is that if the source images of the Enhanced CT do have an FoR, the Enhanced CT object must have the same one, so we must import it. If the images do not have an FoR, we must not try at all importing it. The current content of this object is not deleted before reading. If the log stream is set and valid the, the reason for any error might be obtained from the error/warning output.

Parameters

  filename | Reference to DICOM dataset from which the document should be read
  takeOverCharset | If OFTrue (default), Specific Character Set is taken over from imported dataset. If it's not present or empty (invalid), the attribute will not be present in this class either.

Returns
  EC_Normal if successful, an error code otherwise

## ◆ importFromSourceImage() [2/2]

virtual OFCondition EctEnhancedCT::importFromSourceImage | ( | DcmItem & | dataset,
|  | const OFBool | takeOverCharset = OFTrue )
| virtual

Import Patient, Study, and Frame of Reference level information from the given item.

The method does only import Frame of Reference if Frame of Reference (FoR) UID is found in the image (and no error is reported if not). The reason is that if the source images of the Enhanced CT do have an FoR, the Enhanced CT object must have the same one, so we must import it. If the images do not have an FoR, we must not try at all importing it. If the log stream is set and valid the, the reason for any error might be obtained from the error/warning output.

Parameters

  dataset | Reference to DICOM dataset from which the document should be read
  takeOverCharset | If OFTrue (default), Specific Character Set is taken over from imported dataset. If it's not present or empty (invalid), the attribute will not be present in this class either.

Returns
