ttGlyphPen
- class fontTools.pens.ttGlyphPen.TTGlyphPen(glyphSet: Optional[Dict[str, Any]] = None, handleOverflowingTransforms: bool = True, outputImpliedClosingLine: bool = False)[source]
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 aGlyph
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.
- addVarComponent(glyphName: str, transformation: DecomposedTransform, location: Dict[str, float]) None
Add a VarComponent sub glyph. The ‘transformation’ argument must be a DecomposedTransform from the fontTools.misc.transform module, and the ‘location’ argument must be a dictionary mapping axis tags to their locations.
- closePath() None [source]
Close the current sub path. You must call either pen.closePath() or pen.endPath() after each sub path.
- curveTo(*points) None [source]
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 [source]
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, dropImpliedOnCurves=False) Glyph
Returns a
Glyph
object representing the glyph.- Parameters
componentFlags – Flags to use for component glyphs. (default: 0x04)
dropImpliedOnCurves – Whether to remove implied-oncurve points. (default: False)
- init() None
- property log
- moveTo(pt: Tuple[float, float]) None [source]
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 [source]
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).

- addVarComponent(glyphName: str, transformation: DecomposedTransform, location: Dict[str, float], identifier: Optional[str] = None, **kwargs: Any) None
