OPENDLGOPTIONS_VECTORMISC

typedef struct _OPENDLGOPTIONS_VECTORMISC
{
   L_UINT uStructSize ;
   L_INT nViewportWidth ;
   L_INT nViewportHeight ;
   L_UINT uViewportMode ;
   L_TCHAR szFont [LF_FACESIZE] ;
} OPENDLGOPTIONS_VECTORMISC, L_FAR* LPOPENDLGOPTIONS_VECTORMISC ;

The OPENDLGOPTIONS_VECTORMISC structure provides load option information for certain vector file formats. This information will be used by the L_2DSetViewport, and L_2DSetViewMode 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 the 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 the 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.

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 one of the following:

	FILE_DWF	FILE_CGM
	FILE_CMX	FILE_PCL
	FILE_PCT	FILE_VECTOR_DUMP
	FILE_DRW	FILE_INTERGRAPH_VECTOR
	FILE_SHP	FILE_GERBER
	FILE_SVG	FILE_VWPG

The OPENDLGOPTIONS.pOptions member will point to an OPENDLGOPTIONS_VECTORMISC structure, which is, in turn, updated with the appropriate load options.
