Comments

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.
