# ttGlyphPen

class fontTools.pens.ttGlyphPen.TTGlyphPen(glyphSet: Optional[Dict[str, Any]], handleOverflowingTransforms: bool = True)

  Pen used for drawing to a TrueType glyph.

  This pen can be used to construct or modify glyphs in a TrueType format font. After using the pen to draw, use the `.glyph()` method to retrieve a `Glyph` object representing the glyph.

  addComponent(baseGlyphName: str, transformation: Tuple[float, float, float, float, float, float], identifier: Optional[str] = None, **kwargs: Any) → None

    Add a sub glyph.

  closePath() → None

    Close the current sub path. You must call either pen.closePath() or pen.endPath() after each sub path.

  curveTo(*points) → None

    Draw a cubic bezier with an arbitrary number of control points.

    The last point specified is on-curve, all others are off-curve (control) points. If the number of control points is > 2, the segment is split into multiple bezier segments. This works like this:

    Let n be the number of control points (which is the number of arguments to this call minus 1). If n==2, a plain vanilla cubic bezier is drawn. If n==1, we fall back to a quadratic segment and if n==0 we draw a straight line. It gets interesting when n>2: n-1 PostScript-style cubic segments will be drawn as if it were one curve. See decomposeSuperBezierSegment().

    The conversion algorithm used for n>2 is inspired by NURB splines, and is conceptually equivalent to the TrueType “implied points” principle. See also decomposeQuadraticSegment().

  drawMethod = 'draw'
  endPath() → None

    End the current sub path, but don’t close it. You must call either pen.closePath() or pen.endPath() after each sub path.

  glyph(componentFlags: int = 4) → Glyph

    Returns a `Glyph` object representing the glyph.

  init() → None
  lineTo(pt: Tuple[float, float]) → None

    Draw a straight line from the current point to ‘pt’.

  property log
  moveTo(pt: Tuple[float, float]) → None

    Begin a new sub path, set the current point to ‘pt’. You must end each sub path with a call to pen.closePath() or pen.endPath().

  qCurveTo(*points) → None

    Draw a whole string of quadratic curve segments.

    The last point specified is on-curve, all others are off-curve points.

    This method implements TrueType-style curves, breaking up curves using ‘implied points’: between each two consequtive off-curve points, there is one implied point exactly in the middle between them. See also decomposeQuadraticSegment().

    The last argument (normally the on-curve point) may be None. This is to support contours that have NO on-curve points (a rarely seen feature of TrueType outlines).
