L_VecSetPolygonMode

#include "lvkrn.h"

L_LVKRN_API L_INT L_VecSetPolygonMode(pVector, nMode)

pVECTORHANDLE pVector;	/* pointer to a vector handle */
L_INT nMode;	/* polygon drawing mode */

Sets the current polygon drawing mode.

Parameter	Description
pVector	Pointer to a vector handle.
nMode	The polygon drawing mode to set. Possible values are:

	Value	Meaning
	VECTOR_POLYGON_POINT	Draw only the edges points on polygons and lines.
	VECTOR_POLYGON_LINE	Draw as a wire-frame.
	VECTOR_POLYGON_FILL	Draw solid polygons.
	VECTOR_POLYGON_FILL_RASTER_ALWAYS	Draw solid polygons and always draw raster objects.

Returns

SUCCESS	The function was successful.
< 1	An error occurred. Refer to Return Codes.

Example

This example toggles the polygon mode between Point, Line and Fill.

L_INT VecSetPolygonModeExample(pVECTORHANDLE pVector)
{
   L_INT nRet = FAILURE;
   L_INT nMode;   /* Current polygon mode */

   nMode = L_VecGetPolygonMode( pVector );

   switch( nMode )
   {
      case VECTOR_POLYGON_POINT:
         nRet = L_VecSetPolygonMode( pVector, VECTOR_POLYGON_LINE );
         break;

      case VECTOR_POLYGON_LINE :
         nRet = L_VecSetPolygonMode( pVector, VECTOR_POLYGON_FILL );
         break;

      case VECTOR_POLYGON_FILL :
         nRet = L_VecSetPolygonMode( pVector, VECTOR_POLYGON_FILL_RASTER_ALWAYS );
         break;

      case VECTOR_POLYGON_FILL_RASTER_ALWAYS :
         nRet = L_VecSetPolygonMode( pVector, VECTOR_POLYGON_POINT );
         break;

      default:
