如何从ttf文件中获取汉字笔画顺序？

我发现getGlyphOutline()可以显示JAVA API的字体输出行。 我还没有发现任何用于显示中国笔画顺序的API。 但这是真的： .ttf包含笔画顺序。 我只是不知道如何通过JAVA获得它。

可能是一些我忘记的重要API？

 shape = gv.getGlyphOutline(i, 200, 200); ((Graphics2D) g).draw(shape);

现在，我找到了PathIterator

 Shape shape = gv.getGlyphOutline(0, 200, 200); PathIterator pi = shape.getPathIterator(new AffineTransform()); double[] coords = new double[6]; int count = 0; while (!pi.isDone()) { int kind = pi.currentSegment(coords); int[] path = new int[4]; switch (kind) { case PathIterator.SEG_MOVETO: System.out.println("SEG_MOVETO"); break; case PathIterator.SEG_LINETO: System.out.println("SEG_LINETO"); break; case PathIterator.SEG_CLOSE: System.out.println("SEG_CLOSE"); g.drawLine((int) coords[0], (int) coords[1], (int) coords[2], (int) coords[3]); count++; break; case PathIterator.SEG_QUADTO: System.out.println("SEG_QUADTO"); g.drawLine((int) coords[0], (int) coords[1], (int) coords[2], (int) coords[3]); count++; break; default: throw new IllegalArgumentException("Bad path segment"); } pi.next(); } 

有一个问题，我无法得到完整的字..它看起来像虚线……

你是说要逐个画出角色的笔画 – 就像这段代码一样吗？
