If you are planning to retrieve the text, you should allocate enough space to hold the tag text.
This function retrieves the Sub-Cell tag. The sub-cell tag is the tag that appears only on one frame of the cell frames. You can create a sub-cell tag using the LImageViewerCell::SetSubCellTag function. To create a tag that appears on all the frames of the cell, use the LImageViewerCell::SetCellTag function.
