/**
 * Resolution-independent vector/polygon hardcopy
 *
 * @defgroup HardCopy HardCopy
 *
 * Open Inventor provides you with an action that allows you to render your scene graph using 
 * the PostScript image file format (with SoOffscreenRenderer). 
 * HardCopy extends Open Inventor with new actions that allow you to render your scene graph
 * or part of your scene graph using vector PostScript, HPGL, CGM or GDI 
 * (available only with Windows NT and 95/98) formats. 
 * You cannot use these actions for rendering realistic 3D scenes with smooth shading and 
 * textures. You can use these actions to render resolution-independent output for large 
 * format plotters when your scene is 2D or 3D with wireframe or flat shaded rendering.
 * 
 * As any other modules, this one must be firstly initialized by calling the 
 * method SoHardCopy::init()
 * 
 * @note HardCopy is a separately licensed extension. You must have a HardCopy 
 * license string in addition to your Open Inventor license string.
