一些做过的东西

单页小程序负责编排图片选择与编辑，可测试模块让预览和批量导出共用同一套布局与 Canvas 渲染逻辑；边框宽度按图片短边百分比计算。

A single-page mini program coordinates image selection and editing, while testable modules share the same layout and Canvas rendering logic across preview and batch export. Border width is expressed as a percentage of the image's short edge.

导出格式为 JPG，一组图片共用一套边框参数，并受小程序 Canvas 与设备内存限制。

It exports JPG, applies one shared frame configuration to a batch, and remains subject to mini-program Canvas and device-memory limits.

将列车时刻记录预处理为按车站和城市拆分的 JSON；浏览器只加载所选出发地的数据，并按最短直达时间映射目的地。

Timetable records are preprocessed into station- and city-level JSON fragments. The browser loads only the selected origin and maps destinations by minimum direct travel time.

这是基于 2025 年 3 月数据中直达车次的可达范围，不计算换乘、实时晚点、票价，也不生成连续地理等时面。

This is a reachability view based on direct services in the March 2025 dataset. It does not calculate transfers, real-time delays, fares, or a continuous geographic isochrone surface.

构建期把期刊表预处理为按最佳分区和影响因子预排序的紧凑 JSON；浏览器在每次输入时本地过滤，无后端依赖；支持 ?q= 分享查询链接。

The journal list is preprocessed at build time into a compact JSON pre-sorted by best quartile and impact factor; the browser filters it on every keystroke with no backend, and queries can be shared as ?q= links.

分区与影响因子为 JCR 2026 版（2026 年 6 月 17 日发布，2025 年度指标），不包含中科院分区。

Quartiles and impact factors are the JCR 2026 edition (released 2026-06-17, 2025 indicators). CAS (中科院) partitions are not included.
