OPENDLGOPTIONS_PLT

typedef struct _OPENDLGOPTIONS_PLT
{
   L_UINT uStructSize ;
   L_INT nViewportWidth ;
   L_INT nViewportHeight ;
   L_UINT uViewportMode ;
   L_TCHAR szFont [ LF_FACESIZE ] ;
   FILEPLTOPTIONS PLTOptions ;
} OPENDLGOPTIONS_PLT, L_FAR* LPOPENDLGOPTIONS_PLT ;

The OPENDLGOPTIONS_PLT structure provides load option information for PLT file formats. This information will be used by the L_2DSetViewport, L_2DSetViewMode, and/or L_SetPLTOptions functions.

Member	Description
uStructSize	Size of this structure, in bytes. Use the sizeof operator to calculate this value.
nViewportWidth	New viewport width.
nViewportHeight	New viewport height.
uViewportMode	New viewport mode. Possible values are:
	Value	Meaning
	L2D_USE_BEST	Fit the drawing into the current viewport width and height. Final image size is less than or equal to viewport size.
	L2D_USE_WIDTH	Use the current viewport width. Calculate the new height, preserving the aspect ratio. Final image size has the same width as the current viewport width, with the height less than or equal to the current viewport height.
	L2D_USE_HEIGHT	Use the current viewport height. Calculate the new width, preserving the aspect ratio. Final image size has the same height as the current viewport height, with the width less than or equal to the current viewport width.
	L2D_USE_WIDTH_HEIGHT	Use both the width and the height (stretch image if necessary). Final image size has the same width and height as the current viewport size.
szFont	A string that specifies the typeface name of the font to use in vector font mapping. The length of this string must not exceed 32 characters.
PLTOptions	A FILEPLTOPTIONS structure that contains the load options for a PLT file.

Comments

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_PLT, the OPENDLGOPTIONS.pOptions member will point to an OPENDLGOPTIONS_PLT structure, which is, in turn, updated with the PLT load options.
