| hIGMedElemList | HIGMEDELEMLIST | HIGMEDELEMLIST handle to the Data Element List object. |
| item_index | INT | Index of Data Item in Data Element. |
| lpData | LPVOID | A far pointer to a VOID buffer into which the data will be copied. |
| size_of_lpData | DWORD | Size of above buffer, lpData. |
| lpSize_of_data | LPDWORD | Actual number of bytes copied to lpData (NULL if do not care). This will always be equal to or smaller than size_of_lpData. If lpSize_of_data is less than the VL of the current Data Element then lpData does not contain all the data because lpData does not point to enough memory to hold the entire object. |
Returns the number of ImageGear errors that occurred during the function call.
This function does not process image pixels.
Each Data Element can be of one of many different data types (int, word, bytes, float, double, string, etc.) You must know the VR (Value Representation) of the data in order to use this data.
