// Description: Returns a newly-allocated PNMWriter of the suitable
// type for writing to the already-opened image file, or
// NULL if the file cannot be written for some reason.
//
// owns_file should be set true if the PNMWriter is to
// be considered the owner of the stream pointer (in
// which case the stream will be deleted on completion,
// whether successful or not), or false if it should not
// delete it.
//
// The filename parameter is optional here, since the
// file has already been opened; it is only used to
// examine the extension and attempt to guess the
// intended file type.
//
// If type is non-NULL, it is a suggestion for the file
// type to use.
//
// The PNMWriter should be deleted when it is no longer
// needed.

// A PNMBrush is used to draw the border of a polygon or

// it is used to draw a border, the brush is "smeared"
// over the border; when it is used to fill the
// interior, it is tiled through the interior.

////////////////////////////////////////////////////////////////////
// Class : PNMImage
// Description : The name of this class derives from the fact that we
// originally implemented it as a layer on top of the
// "pnm library", based on netpbm, which was built to
// implement pbm, pgm, and pbm files, and is the
// underlying support of a number of public-domain image
// file converters. Nowadays we are no longer derived
// directly from the pnm library, mainly to allow
// support of C++ iostreams instead of the C stdio FILE
// interface.
//
// Conceptually, a PNMImage is a two-dimensional array
// of xels, which are the PNM-defined generic pixel
// type. Each xel may have a red, green, and blue
// component, or (if the image is grayscale) a gray
// component. The image may be read in, the individual
// xels manipulated, and written out again, or a black
// image may be constructed from scratch.
//
// The image is of size XSize() by YSize() xels,
// numbered from top to bottom, left to right, beginning
// at zero.
//
// Files can be specified by filename, or by an iostream
// pointer. The filename "-" refers to stdin or stdout.

// Description : This class provides a number of convenient methods

// responsible for ensuring that the PNMImage does not
// destruct during the lifetime of the PNMPainter

// Class : TypeHandle
// Description : TypeHandle is the identifier used to differentiate
// C++ class types. Any C++ classes that inherit from
// some base class, and must be differentiated at run
// time, should store a static TypeHandle object that
// can be queried through a static member function
// named get_class_type(). Most of the time, it is also
// desirable to inherit from TypedObject, which provides
// some virtual functions to return the TypeHandle for a
// particular instance.
//
// At its essence, a TypeHandle is simply a unique
// identifier that is assigned by the TypeRegistry. The
// TypeRegistry stores a tree of TypeHandles, so that
// ancestry of a particular type may be queried, and the
// type name may be retrieved for run-time display.

// axis-aligned bounding box, you may be better off with
// the simpler BoundingBox class.
