IGMedElemList Object
| ImageGear Professional v18.2 > API Reference Guide > MD Component API Reference > MD Component Objects > IGMedElemList Object |
This object represents DICOM Element List. IG Medical component uses Element Lists for accessing DICOM Data Set and File Meta Information Header.
Element List is composed of Data Elements. Use navigation functions (Move...) to set current index to the element that you would like to obtain or modify. Use CurrentElem Property. You can also insert new elements to the Element List and remove elements from it.
DICOM standard defines a special type of Data Element called "Sequence of Items" (SQ). Such Data Elements contain a set of Data Elements inside. Thus, Element List can actually represent a tree. Use MoveUp Method and MoveDown Method to go deeper into nested sequences or to go back to the upper levels. The CurrentLevel Property tells on which nesting level the current index is located.
