Gets the current scale value of the specified cell or sub-cell. This feature is available in version 16 or higher.
L_INT LImageViewerCell::GetCellScale(nSubCellIndex, pdScale, uFlags)
A zero-based index into the image list attached to the cell. The scale for this sub-cell will be retrieved. This sub-cell scale will be retrieved. Pass -2 to retrieve the scale of the selected sub-cell.
Address of the variable to be updated with the scale value.
Reserved for future use. Pass 0.

Currently, there are two ways to fit an image to a cell. One is by setting the bIsFit value of the DISPCELLPROPERTIES structure to true (also remembering to set the corresponding uMask value), and then send this structure to the LImageViewerCell::SetCellProperties function. The other method is by using the LImageViewerCell::GetCellScale and LImageViewerCell::SetCellScale functions. If using these make sure that bIsFit is set to FALSE.
To set the scale of a cell or sub-cell call LImageViewerCell::SetCellScale function, and to set the properties of the scale action use the LImageViewerCell::SetActionProperties function. To retrieve the properties of the scale action use the LImageViewerCell::GetActionProperties function. To set the scale mode of a cell or sub-cell call the LImageViewerCell::SetCellScaleMode function and to get it call the LImageViewerCell::GetCellScaleMode function.
For an example, refer to LImageViewerCell::BeginUpdate.
