Comments

If you are planning to retrieve the text, be sure to allocate enough space to hold the tag text.

This function retrieves the Cell tag. The cell tag is the tag that appears on all the frames in the cell. You can create a cell tag using the LImageViewerCell::SetCellTag function.

To create a tag that appears only on the desired frame, use the LImageViewerCell::SetSubCellTag function.
