Java 如何从ttf文件中获取汉字笔画顺序?

Java 如何从ttf文件中获取汉字笔画顺序?,java,swing,fonts,Java,Swing,Fonts,我发现getGlyphOutline()可以显示JAVA API中的字体输出行。 而且我还没有找到任何显示中国笔画顺序的API。 但这是事实:.ttf包含笔划顺序。 我只是不知道如何通过JAVA获得它 可能有一些重要的API我忘了 shape = gv.getGlyphOutline(i, 200, 200); ((Graphics2D) g).draw(shape); 现在,我找到了PathIterator Shape shape = gv.getGlyphOutl

我发现
getGlyphOutline()
可以显示JAVA API中的字体输出行。 而且我还没有找到任何显示中国笔画顺序的API。 但这是事实:.ttf包含笔划顺序。 我只是不知道如何通过JAVA获得它

可能有一些重要的API我忘了

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();
        }
有个问题,我找不到完整的单词。。
它看起来像虚线…
