VEC2DOPTIONS

typedef struct _VEC2DOPTIONS 
{ 
   L_UINT uStructSize; 
   L_INT nViewWidth; 
   L_INT nViewHeight; 
   VECTORVIEWMODE ViewMode; 
} VEC2DOPTIONS, *pVEC2OPTIONS;

The VEC2DOPTIONS structure specifies options for the viewport (physical size up to which the drawing can be rendered) mode and dimensions for loading a vector file in LEADTOOLS.

Member	Description
uStructSize	Size of the structure. This must be set before passing this structure to the LEAD functions. Use the sizeof() macro to calculate this value.
nViewWidth	Viewport width for a vector file
nViewHeight	Viewport height for a vector file
ViewMode	View mode that controls how to use the width and height. For possible values refer to VECTORVIEWMODE.

Comments

pVEC2DOPTIONS is a pointer to a VEC2DOPTIONS structure. Where the function parameter type is pVEC2DOPTIONS, you can declare a VEC2DOPTIONS variable, update the structure's fields, and pass the variable's address in the parameter. Declaring a pVEC2DOPTIONS variable is necessary only if your program requires a pointer.
