Note:

More options are available in the LOADFILEOPTION structure.

For an explanation of how LEADTOOLS uses the WMF/EMF file resolution value, refer to L_SetWMFResolution.

Before calling this function, you must declare two variables of data type L_INT. You can then pass the address of these variables in the pXResolution and pYResolution parameters, which this function will update with the current values that LEADTOOLS uses for WMF/EMF resolution.
