Detailed Description

Class for exporting a scene graph to a PDF file.

This class can export an Open Inventor scenegraph into a simple PDF file. In addition to 3D scene encapsulation, the exporter can insert a title to the document and an unique block of text. Moreover, PDF encryption can lock access to the file contents. To import a 3D model inside a more complex PDF file, prefer SoToU3DAction. U3D files can be used to import 3D models inside PDF files by advanced PDF editors.

Limitations

Inherits limitations of SoToU3DAction. Please read these carefully.

Use case

SoHardCopy::init();
...
// setup the root scene graph to export
SoSeparator* root = new SoSeparator;
...
SoToPDFAction pdfAction;
bool result = pdfAction.openFile( "output.pdf" );
if ( !result ) 
{
  // error management
}
pdfAction.setTitle( "Scene Name" );
pdfAction.setText( "Some text describing the exported scene." );
pdfAction.apply( root );
result = pdfAction.closeFile();
if ( !result )
{
  // error management
}

Warning

On some platforms, some third parties may encounter problems to load displaying an error message like: "IFXOSFileIterator::ProcessDir: error opening /usr/local/u3d/lib/Plugins/ No such file or directory". In such case, declare the environment variable U3D_LIBDIR (UNIX only) and set it with the path to the Open Inventor libraries ($OIVHOME/lib).
Limitations are common to SoToU3DAction.
