VEC2DOPTIONS

Summary

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.

Syntax

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

Members

uStructSize

Size of the structure. This must be set before passing this structure to the LEAD functions. Use the sizeof() operator 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.
