typedef struct _OPENDLGOPTIONS_METAFILE{L_UINT uStructSize ;L_INT nXResolution ;L_INT nYResolution ;} OPENDLGOPTIONS_METAFILE, * LPOPENDLGOPTIONS_METAFILE ;
The OPENDLGOPTIONS_METAFILE structure provides load option information for Metafile file formats. This information will be used in the L_SetWMFResolution function.

Description |
uStructSize |
Size of this structure, in bytes. Use the sizeof operator to calculate this value. |
nXResolution |
The X-resolution value that LEADTOOLS is to use when loading images from WMF files. Load the file at the corresponding DPI. |
nYResolution |
The Y-resolution value that LEADTOOLS is to use when loading images from WMF files. Load the file at the corresponding DPI. |
The L_DlgOpen function displays the Open dialog and gets options for the L_LoadFile function. After the user presses the Open button on the dialog, one or more OPENDLGFILEDATA structures will be updated based on the file(s) selected in the Open dialog. The OPENDLGFILEDATA.FileOptions member is an OPENDLGOPTIONS structure. This structure is updated based on the file type(s) selected in the Open dialog. If the OPENDLGOPTIONS.nType member is FILE_EMF or FILE_WMF, the OPENDLGOPTIONS.pOptions member will point to an OPENDLGOPTIONS_METAFILE structure, which is, in turn, updated with the Metafile load options.
