本人开发了一款软件，可以设计印章；不但可以将印章保存为图片，而且可以保存为ofd格式文件。
将印章保存为ofd格式，有很多优势：占用资源少、缩放不失真、可添加元数据。
矢量化图形格式一般为svg、pdf。很少人会用ofd保存矢量化图形，概因缺少相应的工具也。
ofd就是国产化的pdf，采用ofd保存矢量化的图形完全没有问题。
设计思路
印章外形也许有国家标准，我并没费神去查找国家标准；只是简单的分析了一下印章，印章应该符合如下条件：
1 外形是椭圆或圆 2 曲线字体应该均匀分布，并且字与对应的椭圆切线平行。
印章有三部分组成：椭圆、曲线文字、直线文字。
设计步骤
添加两个椭圆
添加曲线文字
添加直线文字
只需简单的设置一些参数，印章就设计完成。并且可以转化为图片或ofd。
