| Name | Type | Description |
|---|---|---|
| hIGear | const HIGEAR | The HIGEAR handle to the image. |
| index | const DWORD | Set to a DWORD that indicates the index that you would like to become the new Current Data Element. |
| lpTag | LPAT_DCM_TAG | A far pointer that returns a 32-bit value of type AT_DCM_TAG indicating the numerical value of the Tag of the Current Data Element; set this to NULL if you do not need this information. The numerical values of the DICOM Tags are defined in enumIGMedTag enumeration. |
| lpVR | LPAT_DCM_VR | A far pointer which returns the new current VR (Value Representation). Set to NULL if you don't need this information. See enumIGMedVR for possible VR values. |
| lpVL | LPAT_DCM_VL | A far pointer which returns the length of the Data Field, in bytes. |
| lpLevel | LPDWORD | A far pointer to a WORD which returns the level in the hierarchy of the new Current Data Element; set to NULL, if you do not need this information. |
| lpICount | LPDWORD | Returns the Item Count of the data; set to NULL if you don't need this information. |
Returns the number of ImageGear errors that occurred during the function call.
This function does not process image pixels.
The image must have a DICOM DataSet attached to it. Use MED_DCM_DS_exists to check whether the image contains a DataSet.
This function also returns the Tag's VR (Value Representation), its Tag value, the number of bytes in the Tag's data, and the Item Count. The index refers to which element in the Data Element array should be used. The first Data Element will always have an index of 0, and the last Data Element will always have an index of (Total # of DEs - 1). Use MED_DCM_DS_info_get() to find out the total # of Data Elements associated with an image's Data Set.
This function pays no attention to Levels. It only returns the level of the Current Data Element.
