Glossary Item Box

This function searches the Element List for the Tag specified in Tag.

Declaration:

  Copy Code 
AT_ERRCOUNT ACCUAPI MED_ElemList_move_find(
        HIGMEDELEMLIST hIGMedElemList, 
        const AT_MODE level_op, 
        const AT_DCM_TAG Tag,
        LPBOOL lpTagFound
);

Arguments:

Name Type Description
hIGMedElemList HIGMEDELEMLIST HIGMEDELEMLIST handle to the Data Element List object.
level_op const AT_MODE

A variable of type AT_MODE that tells the function how to move when it comes to an SQ. SQs are like indented outline items, allowing for hierarchies of Data Elements. Set this to one of the following constants:

  • MED_DCM_MOVE_LEVEL_FIXED: This setting tells the function to move only within the same level as the previous Current DE. An SQ and all its Data Elements are skipped over. If you are in a SQ, you can only move about the SQ.
  • MED_DCM_MOVE_LEVEL_FLOAT: This setting tells the function to move up or down as needed to get to the next DE. If the next DE is an SQ the Current DE moves down into it. At the end of the SQ, the Current DE will move back out to the lower levels (for example, from Level 2 to Level 1).
Tag const AT_DCM_TAG Set to a value of type DWORD that identifies the Tag value you would like to search for. The first 16 bits of the DWORD represent the Group Number; the second 16 bits represent the Element Number.
lpTagFound LPBOOL Returns TRUE is the Tag was found; FALSE otherwise.

Return Value:

Returns the number of ImageGear errors that occurred during the function call.

Supported Raster Image Formats:

This function does not process image pixels.

Remarks:

If the Tag is found, the Data Element becomes the Current Data Element.

The levels of the Element List that will be searched depends on the setting of level_op.
