L_VecSetPolygonMode

Summary

Sets the current polygon drawing mode.

Syntax

#include "ltvkrn.h"

L_LVKRN_API L_INT L_VecSetPolygonMode(pVector, nMode)

Parameters

pVECTORHANDLE pVector

Pointer to a vector handle.

L_INT 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

Value	Meaning
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_LTVKRNTEX_API 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: 
         break;
