4.2.2. Simple approach

The class SoToPDFAction⁽^C++^|^Java^|^.NET⁾ exports an Open Inventor scene graph directly into a simple PDF file. SoToPDFAction⁽^C++^|^Java^|^.NET⁾ can also set the document title, specify the text of the document, and lock access to the file content.

Example 4.5. Generation of PDF3D output

C++

SoSeparator* root = ...         // scenegraph init
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

The sample demo $OIVHOME/src/HardCopy/PDFExport shows how to convert an Open Inventor file. This demo brings up the dialog box shown below. Fill in a few fields and click on the Export button.

Figure 4.3. Open Inventor to PDF3D conversion tool.

This demo can also be used as a command line tool. The first argument is the Open Inventor input filename. The second (optional) argument is the output PDF filename. For example:

PDFExport harley.iv output.pdf

Figure 4.4. Harley.iv exported to PDF3D view.
