## addFrame() [1/2]

template<typename T>

OFCondition DcmSegmentation::addFrame | ( | T * | pixData | ) |

Parameters

  pixData | Pixel data to be added. Length must be rows*columns bytes. Pixel data is copied so it must be freed by the caller.

Returns
  EC_Normal if adding was successful, error otherwise

## addFrame() [2/2]

template<typename T>

OFCondition DcmSegmentation::addFrame | ( | T * | pixData,
|  | const Uint16 | segmentNumber,
|  | const OFVector< FGBase * > & | perFrameInformation )

Add frame to segmentation object.

Parameters

  pixData

  Pixel data to be added. Length must be rows*columns bytes.
  - For binary segmentations (bit depth i.e. Bits Allocated/Stored=1), each byte equal to 0 will be interpreted as "not set", while every other value is interpreted as "set".
  - For fractional segmentations the full byte is copied as is.
  - For labelmap segmentations, the value of each byte is interpreted as the segment number. In that case the segmentNumber parameters is ignored.

  segmentNumber | The logical segment number (>=1) this frame refers to. The segment identified by the segmentNumber must already exist. For labelmap segmentations, this parameter is ignored.
  perFrameInformation | The functional groups that identify this frame (i.e. which are planned to be not common for all other frames). The functional groups are copied, so ownership of each group stays with the caller no matter what the method returns.

Returns
  EC_Normal if adding was successful, error otherwise

## addSegment()

virtual OFCondition DcmSegmentation::addSegment | ( | DcmSegment * | seg,
|  | Uint16 & | segmentNumber )

virtual

Add segment to segmentation object.

Parameters

  seg | The segment that should be added

  segmentNumber

  Depending on the type of segmentation, this parameter is handled differently:
  - For binary and fractional segmentations the segment number is automatically assigned and will be returned in this parameter. It is assigned from 0 onwards, i.e. the first segment added will have segment number 1, the second 2, etc.
  - For labelmap segmentations, the segment number is taken from this parameter and can be >= 0. If the segment number is already used, the method will overwrite an old segment with this number.

  EC_Normal if adding was successful, error otherwise

virtual OFCondition DcmSegmentation::importFromSourceImage | ( | const OFString & | filename,

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 segmentation do have an FoR, the segmentation 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

The reason is that if the source images of the segmentation do have an FoR, the segmentation 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
