当你有如下需求之一时，这个工具适合你： 4 | 5 | 1. 设计师给你一个 SVG 文件，你需要在 XAML 系的开发框架中使用； 6 | 2. 你需要生成一个 Geometry，以便自己组装图形。 7 | 8 | ![主界面截图](/docs/img/main_screenshot.png) 9 | 10 | 本工具基于 [ElinamLLC/SharpVectors](https://github.com/ElinamLLC/SharpVectors)。不过 SharpVectors 适用于 SVG 转 XAML 的全场景，在部分小场景下却效率不高。本工具旨在解决这一小部分问题。 11 | 12 | ## 相似的项目 13 | 14 | -
