本文介绍了如何从ttf文件中获取汉字笔顺？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我发现 getGlyphOutline（）可以从JAVA API显示字体。
，我还没有找到任何API显示一个中文笔顺。
，但这是真的： .ttf 包含笔顺。
i只是不知道如何通过JAVA获得它。
可能是我忘记的一些重要的API？
shape = gv.getGlyphOutline（i，200，200）;
（（Graphics2D）g）.draw（shape）;
现在，我发现PathIterator
形状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;
默认值：
抛出新的IllegalArgumentException（Bad path segment）;
}
pi.next（）;
$有一个问题，我不能得到完整的单词..
看起来像虚线... 解决方案你的意思是画出角色部分的笔画 - 像这样的代码？

i find getGlyphOutline() can show font out line from JAVA API.and i have not found out any API for show one chinese stroke order.but this is true: .ttf contain the stroke order.i just don't know how to get it by JAVA.
May be some important APIs i forget?
shape = gv.getGlyphOutline(i, 200, 200);
((Graphics2D) g).draw(shape);
now, i found 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;

throw new IllegalArgumentException("Bad path segment");
}
pi.next();
}
There is a problem, i can not get complete word..It looks like dotted line...
解决方案 Do you mean to draw the strokes of the characters 'part by part' - something like this code?
