| class | DcmRepresentationEntry |
A type (or transfer syntax) conforms to a representation if the type and the representation type are equal or both are unencapsulated. If this is valid for the representation read or set by chooseRepresentation then this representation is the conforming representation. else a representation with the default parameter set defined in the codec is the conforming representation.

returns length of representation conforming to the transfer syntax with tag, vr, . .. It does not create a representation. If no conforming representation exists an error code is set and 0 returned. Reimplemented from DcmElement. |

|
choose a specific representation. if representation does not exist it is created (if possible). if repParam is zero, a representation is chosen or created that is equal to the default representation parameters |
|

This function removes all pixel representations from the list of pixel representations except the one which was passed. Note that if parameter leaveInList equals repListEnd, all representations will be removed from the list.

find a representation entry and return an iterator to the found entry or the next element in the list. The condition returned can be EC_Normal if such an entry is found or EC_RepresentationNotFound. The pixSeq attribute in findEntry can be NULL, it is not needed for the find operation! |

This function reads the data value of a pixel data attribute which is captured in the input stream and captures this information in this. This function takes into account, if the pixel data is captured in native (uncompressed) or encapsulated (compressed) format.
Reimplemented from DcmPolymorphOBOW. |

delete original representation and set new original representation. If the new representation does not exist, the original one is not deleted and an error code returns |

delete a representation. It is not possible to delete the original representation with this method |
|
|
set or clear the flag that indicates that this pixel data element will be written in uncompressed (defined length) format even if the dataset itself is written in a compressed syntax where pixel data is normally written in encapsulated (undefined length) format. By default this flag is false, unless the dataset was read in an encapsulated transfer syntax and this pixel data element was already present in uncompressed format. This flag should never be enabled for pixel data elements on the main dataset level, only for pixel data elements within the icon image sequence or some other "private" place.

this flag indicates that this pixel data element will be written in uncompressed (defined length) format even if the dataset itself is written in a compressed syntax where pixel data is normally written in encapsulated (undefined length) format. By default this flag is false, unless the dataset was read in an encapsulated transfer syntax and this pixel data element was already present in uncompressed format. |
