SVG <path > 笔画和 detexify 数据库 'strokes'。如何从上到下？
SVG <path > strokes and detexify database 'strokes'. How to go from on to the other?
我正在尝试通过使用 mathjax 将 tex 转换为 svg 然后将 svg 路径更改为从 detexify 数据库获得的“笔画”来生成手写数学文本 github。
如何转换 Detexify 的笔画：
The „strokes“ column contains an array of strokes each of which contains an array of [x,y,t] triples. [[[x1,y1,t1], [x2,y2,t2], …], …].
转为 svg 格式。
例子：取latex \sqrt
对于 svg 文件：

将 x,y 绘制为折线并忽略 t 值。如果你真的想使用路径，那么在前面贴一个 M 并类似地添加所有忽略 t 值的 x,y 值。
完成该工作后，您可以延迟将每个顶点添加到 polyline/path 时间增量 tn+1-tn
