 - 调整 GIF 图的速度。若为负数，则代表倒放。

+### `--pingpong`（可选）
+
+- 开启乒乓模式，生成正放-倒放拼接的 GIF 图。
+- 即播放完正向后，会倒放回去，形成往复循环效果。
+- 可与 `--speed` 配合使用，调整播放速度。
+- 示例：`giftool [图片] --pingpong`
+- 示例：`giftool [图片] --pingpong --speed 2.0`

pi-agent	f21b7067df	fix: use Query to properly handle --pingpong flag Use nonebot_plugin_alconna Query to correctly handle the --pingpong boolean flag. Previously the flag wasn't working because the parameter wasn't being properly injected. Changes: - Import Query from nonebot_plugin_alconna - Change Option to not have args (just Option('--pingpong')) - Use Query[bool] type annotation with default Query('pingpong') - Check pingpong.available to determine if flag was set	2026-04-02 20:34:23 +08:00

pi-agent	b87c58485c	feat: add --pingpong flag to giftool Add pingpong mode to giftool command. When --pingpong flag is used, the generated GIF will play forward then backward, creating a back-and-forth looping effect. Features: - Add --pingpong option to giftool command - Support combining with --speed for adjusted playback speed - Update documentation with new option Examples: - giftool [图片] --pingpong - giftool [图片] --pingpong --speed 2.0	2026-04-02 20:06:15 +08:00
