Comments

Before calling this function, the user must declare two variables of L_INT data type, and then pass the addresses of these variables as the lpXResolution and lpYResolution parameters, and then the function will update these values with the current values that LEADTOOLS uses for WMF/EMF resolutions.

For an explanation of how LEADTOOLS uses the WMF/EMF file resolution values, refer to LFileSettings::SetWMFResolution function.

Note: More options are available in the LOADFILEOPTION structure.
