Examples

The following examples (located in $OIVHOME/examples/source/HardCopy/Mentor) show you how to use each of the four possible output types.

PostScript Output

#include <Inventor/nodes/SoSphere.h>
 
int
main( int, char** argv )
{
  // Initialize HardCopy
  SoHardCSoHardCopy::init();
 
  // Create the root of the scene graph
  SoSeparator* root = new SoSeparator;
  root->ref();
 
  // Create the Camera node
  SoPerspectiveCamera* myCam = new SoPerspectiveCamera;
  root->addChild( myCam );
 
  // Use wireframe draw style
  SoDrawStyle* drawStyle = new SoDrawStyle;
  drawStyle->style = SoDrawStyle::LINES;
  root->addChild( drawStyle );
 
  // Create a simple sphere
  SoSphere* shape = new SoSphere;
  root->addChild( shape );
 
  myCam->viewAll( root, SbViewportRegion( 1000, 1000 ) );
 
  // Create and apply the PostScript action.
  SoVectorizePSAction vect;
 
  vect.setStartPosition( 0, 0 );
  vect.setDrawingDimensions( 80, 80 );
  vect.setOrientation( SoVectorizeAction::PORTRAIT );
  vect.setBorder( 1. );
  vect.setColorTranslationMethod( SoVectorizeAction::REVERSE_ONLY_BLACK_AND_WHITE );
  vect.setLineEndStyle( SoVectorizeAction::BUTT_END );
  vect.setLineJoinsStyle( SoVectorizeAction::ROUNDED_JOIN );
  vect.setMiterLimit( 2. );

  SoVectorizeHPGLAction vect;
 
  vect.setStartPosition( 10, 20 );
  vect.setDrawingDimensions( 130, 100 );
  vect.setOrientation( SoVectorizeAction::PORTRAIT );
  // Black and white.
  vect.setPenDescription( 2 );
  // width = 0.35mm.
  vect.setBorder( 1., SbVec3f( 0., 0., 0. ) );
  vect.setBackgroundColor( TRUE, SbVec3f( 1., 1., 1. ) );

  vect.setStartPosition( 10, 20 );
  vect.setDrawingDimensions( 130, 100 );
  vect.setBorder( 1. );
  vect.setBackgroundColor( TRUE );
  // Black and White are reversed !
  vect.setColorTranslationMethod( SoVectorizeAction::REVERSE_ONLY_BLACK_AND_WHITE );
  // Version 1, Clear Text and RGB.
  vect.getOutput()->setVersion( 1 );
  vect.getOutput()->setIndexed( FALSE );
