OSG specific gluScaleImage function that allows you to pass in the PixelStoreModes, which enables the code to avoid glGet's that are associated with the conventional gluScaleImage function.

Avoiding glGet's allows this gluScaleImage function to be called at any time, from any thread, there is no need to have a graphics context current.

; The use of glGet's means that you can only call this function from a thread with a valid graphics context. The use of glGet's will also result in lower performance due to the round trip to the OpenGL driver.

OSG_EXPORT std::ostream& osg::notify ( const NotifySeverity  severity)

notify messaging function for providing fatal through to verbose debugging messages.

Level of messages sent to the console can be controlled by setting the NotifyLevel either within your application or via the an environmental variable i.e.

  • setenv OSGNOTIFYLEVEL DEBUG (for tsh)
  • export OSGNOTIFYLEVEL=DEBUG (for bourne shell)
  • set OSGNOTIFYLEVEL=DEBUG (for Windows)

All tell the osg to redirect all debugging and more important messages to the notification stream (useful for debugging) setting ALWAYS will force all messages to be absorbed, which might be appropriate for final applications. Default NotifyLevel is NOTICE. Check the enum NotifySeverity for full range of possibilities. To use the notify with your code simply use the notify function as a normal file stream (like std::cout) i.e

 osg::notify(osg::DEBUG) << "Hello Bugs!" << std::endl;

Set a list of extensions to disable for different OpenGL renderers.

This allows OSG applications to work around OpenGL drivers' bugs which are due to problematic extension support.
