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.

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.

The following functions make use of this structure:

L_GetVectorOptions

L_SetVectorOptions
