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 function L_DispContainerSetCellProperties. The other method is by using the L_DispContainerGetCellScale and L_DispContainerSetCellScale functions. If using these make sure that bIsFit is set to FALSE.

To set the scale of a cell or sub-cell call L_DispContainerSetCellScale, and to set the properties of the scale action use the L_DispContainerSetActionProperties function. To retrieve the properties of the scale action use the L_DispContainerGetActionProperties function. To set the scale mode of a cell or sub-cell call the L_DispContainerSetCellScaleMode function and to get it call L_DispContainerGetCellScaleMode.
