+"""fontTools.pens.basePen.py -- Tools and base classes to build pen objects.
+
+The Pen Protocol
+
+A Pen is a kind of object that standardizes the way how to "draw" outlines:
+it is a middle man between an outline and a drawing. In other words:
+it is an abstraction for drawing outlines, making sure that outline objects
+don't need to know the details about how and where they're being drawn, and
+that drawings don't need to know the details of how outlines are stored.
+
+The most basic pattern is this::
+
+	outline.draw(pen)  # 'outline' draws itself onto 'pen'
+
+Pens can be used to render outlines to the screen, but also to construct
+new outlines. Eg. an outline object can be both a drawable object (it has a
+draw() method) as well as a pen itself: you *build* an outline using pen
+methods.
+
+The AbstractPen class defines the Pen protocol. It implements almost
+nothing (only no-op closePath() and endPath() methods), but is useful
+for documentation purposes. Subclassing it basically tells the reader:
+"this class implements the Pen protocol.". An examples of an AbstractPen
+subclass is :py:class:`fontTools.pens.transformPen.TransformPen`.
+
+The BasePen class is a base implementation useful for pens that actually
+draw (for example a pen renders outlines using a native graphics engine).
+BasePen contains a lot of base functionality, making it very easy to build
+a pen that fully conforms to the pen protocol. Note that if you subclass
+BasePen, you *don't* override moveTo(), lineTo(), etc., but _moveTo(),
+_lineTo(), etc. See the BasePen doc string for details. Examples of
+BasePen subclasses are fontTools.pens.boundsPen.BoundsPen and
+fontTools.pens.cocoaPen.CocoaPen.
+
+Coordinates are usually expressed as (x, y) tuples, but generally any
+sequence of length 2 will do.

+    Example: You have some TrueType hinting code for a glyph which you want to
+    compile. The hinting code specifies a hash value computed with HashPointPen
+    that was valid for the glyph's outlines at the time the hinting code was
+    written. Now you can calculate the hash for the glyph's current outlines to
+    check if the outlines have changed, which would probably make the hinting
+    code invalid.
+
+    > glyph = ufo[name]
+    > hash_pen = HashPointPen(glyph.width, ufo)
+    > glyph.drawPoints(hash_pen)
+    > ttdata = glyph.lib.get("public.truetype.instructions", None)
+    > stored_hash = ttdata.get("id", None)  # The hash is stored in the "id" key
+    > if stored_hash is None or stored_hash != hash_pen.hash:
+    >    logger.error(f"Glyph hash mismatch, glyph '{name}' will have no instructions in font.")
+    > else:
+    >    # The hash values are identical, the outline has not changed.
+    >    # Compile the hinting code ...
+    >    pass
+
+    If you want to compare a glyph from a source format which supports floating point
+    coordinates and transformations against a glyph from a format which has restrictions
+    on the precision of floats, e.g. UFO vs. TTF, you must use an appropriate rounding
+    function to make the values comparable. For TTF fonts with composites, this
+    construct can be used to make the transform values conform to F2Dot14:
+
+    > ttf_hash_pen = HashPointPen(ttf_glyph_width, ttFont.getGlyphSet())
+    > ttf_round_pen = RoundingPointPen(ttf_hash_pen, transformRoundFunc=partial(floatToFixedToFloat, precisionBits=14))
+    > ufo_hash_pen = HashPointPen(ufo_glyph.width, ufo)
+    > ttf_glyph.drawPoints(ttf_round_pen, ttFont["glyf"])
+    > ufo_round_pen = RoundingPointPen(ufo_hash_pen, transformRoundFunc=partial(floatToFixedToFloat, precisionBits=14))
+    > ufo_glyph.drawPoints(ufo_round_pen)
+    > assert ttf_hash_pen.hash == ufo_hash_pen.hash

+PointPens
+=========

+Where **SegmentPens** have an intuitive approach to drawing
+(if you're familiar with postscript anyway), the **PointPen**
+is geared towards accessing all the data in the contours of
+the glyph. A PointPen has a very simple interface, it just
+steps through all the points in a call from glyph.drawPoints().
+This allows the caller to provide more data for each point.
+For instance, whether or not a point is smooth, and its name.
