TTGlyphPen
(glyphSet: Optional[Dict[str, Any]], handleOverflowingTransforms: bool = True)[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.
-
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

-
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) → fontTools.ttLib.tables._g_l_y_f.Glyph¶ Returns a
Glyph
object representing the glyph.

init
() → None¶
-
lineTo
(pt: Tuple[float, float]) → None[source]¶ Draw a straight line from the current point to ‘pt’.

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).
