L_UINT16 LDicomDS::GetInfoImage(pElement, pInfo, nIndex)
pDICOMELEMENT pElement; |
/* pointer to a DICOMELEMENT structure */ |
pDICOMIMAGE pInfo; |
/* pointer to a DICOMIMAGE structure */ |
L_UINT32 nIndex; |
/* index value */ |
Retrieves information about the specified image.
Parameter |
Description |
pElement |
Pointer to a DICOMELEMENT structure within the Data Set. |
pInfo |
Pointer to a DICOMIMAGE structure that contains the information about the specified image. |
nIndex |
Index value that indicates the position of the image. This is a zero-based index. For example, if nIndex is 0, information about the first image in the Pixel Data Element will be retrieved. |
Returns
0 |
SUCCESS |
>0 |
An error occurred. Refer to Return Codes. |
Comments
Most DICOM files will only have one Data Element of type TAG_PIXEL_DATA. Therefore, in most instances you can set pElement to NULL, since the function will automatically retrieve information about the image at the specified index within the only Pixel Data Element in the file. If pElement is not NULL, it must point to the Pixel Data Element itself.
If the DICOM file is CLASS_BASIC_DIRECTORY, the file may contain more than one Pixel Data Element. In this case you must specify in pElement the Pixel Data Element from which to get the image information.
