Detailed Description

The SoVectorizePSAction class is used for rendering to a Postscript file.

Since:
    Coin 2.1

    TGS provides HardCopy support as a separate extension for TGS Inventor.

Constructor & Destructor Documentation

  SoVectorizePSAction::SoVectorizePSAction (void)
Default constructor.

  SoVectorizePSAction::~SoVectorizePSAction () [virtual]
Default destructor.

Member Function Documentation

  SoType SoVectorizePSAction::getTypeId (void) const [virtual]
Returns the type identification of an action derived from a class inheriting SoAction. This is used for run-time type checking and 'downward' casting.

Usage example:

void bar(SoAction * action)
{
  if (action->getTypeId() == SoGLRenderAction::getClassTypeId()) {
    // safe downward cast, know the type
    SoGLRenderAction * glrender = (SoGLRenderAction *)action;
  }
  return; // ignore if not renderaction
}

For application programmers wanting to extend the library with new actions: this method needs to be overridden in all subclasses. This is typically done as part of setting up the full type system for extension classes, which is usually accomplished by using the pre-defined macros available through Inventor/nodes/SoSubAction.h: SO_ACTION_SOURCE, SO_ACTION_INIT_CLASS and SO_ACTION_CONSTRUCTOR.

For more information on writing Coin extensions, see the SoAction class documentation.

Returns the actual type id of an object derived from a class inheriting SoAction. Needs to be overridden in all subclasses.

Reimplemented from SoVectorizeAction.

  void SoVectorizePSAction::addMethod (const SoType type, SoActionMethod method) [static]
This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.

  void SoVectorizePSAction::enableElement (const SoType type, const int stackindex) [static]
This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.

  const SoEnabledElementsList & SoVectorizePSAction::getEnabledElements (void) const [protected], [virtual]
Returns a list of the elements used by action instances of this class upon traversal operations.

Reimplemented from SoVectorizeAction.

  void SoVectorizePSAction::setDefault2DFont (const SbString & fontname)
Sets the default font name. This font will be used for rendering Text2-nodes which have no Font-nodes preceding them. The default value is 'Courier'.

  const SbString & SoVectorizePSAction::getDefault2DFont (void) const
Returns the default font name.

See also:
    setDefault2DFont()

  void SoVectorizePSAction::setGouraudThreshold (const double eps)
Sets the Gouraud shading threshold. A threshold of 0.0 will disable Gouraud shading. A smaller value will yield more accurate Gouraud shading. Default is 0.1.

Since the postscript language has no support for Gouraud shaded triangles, each triangle will be split into subtriangles approximately of size eps postscript units. One postscript unit is approximately 1/72 inch.

  SoPSVectorOutput * SoVectorizePSAction::getOutput (void) const
Returns the SoPSVectorOutput used by this instance.

  SoPSVectorOutput * SoVectorizePSAction::getPSOutput (void) const
Returns the SoPSVectorOutput used by this instance. Provided for API compatibility with TGS HardCopy support.

  void SoVectorizePSAction::printHeader (void) const [protected], [virtual]
This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.

Implements SoVectorizeAction.

  void SoVectorizePSAction::printFooter (void) const [protected], [virtual]
This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.

Should be overridden by subclasses to print file footer data.

Reimplemented from SoVectorizeAction.

  void SoVectorizePSAction::printBackground (void) const [protected], [virtual]
This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.

Should be overridden by subclasses to print background data.

Reimplemented from SoVectorizeAction.

  void SoVectorizePSAction::printItem (const SoVectorizeItem * item) const [protected], [virtual]
This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.

Should be overridden by subclasses to print an item.

Implements SoVectorizeAction.

  void SoVectorizePSAction::printViewport (void) const [protected], [virtual]
This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.

Should be overridden by subclasses to set up the current page viewport.

Reimplemented from SoVectorizeAction.
