Clone 项目到本地。 10 | 2. `npm install`。 11 | 3. 使用 `scripts/loadPic.py` 生成图片的 `json` 格式，将其放到项目 `pictures` 目录下。 12 | - 需要安装 PIL 库：`pip install pillow`。 13 | 4. 复制 `config-example.json` 为 `config.json`，并配置以下内容： 14 | 1. `picFile`：生成好的图片，支持多张图同时绘制： 15 | - `name`：`json` 文件名。 16 | - `x`,`y`：绘制时的坐标偏移量。 17 | 2. `fetchTime`：更新地图的时间间隔，建议不要太小。（单位为 ms） 18 | 3. `paintTime`：每个用户每次 paint 的时间间隔，建议比洛谷限制稍大。（单位为 ms） 19 | 4. `random`：如果为 `true`，则每次随机选择需要绘制的点进行绘制；否则按「图片编号为第一关键字、坐标顺序为第二关键字」排序然后绘制。 20 | 5. `users`：绘制所用的用户 `token`，可添加多个。 21 | 5. `npm start`，开始你的创作！ 22 | 23 | ## Thanks 24 | 25 | - Luogu-Painter 使用的 `scripts/loadPic.py` 是 [AimonaStudio/luogu-drawer](https://github.com/AimonaStudio/luogu-drawer/blob/master/scripts/main.py) 里的脚本的修改版，非常感谢！ 26 | - 感谢为 Luogu-Painter 提供测试的
