某珍宝馆图片下载，自动合并
本帖最后由 hebeijianke 于 2024-7-26 21:29 编辑看到求助帖有人需要 @幸甚至哉
代码比较简单，只能下载较小的图片，图像的宽度和高度小于65500像素，好像python的几个图像处理模块都对拼接大图有限制，
注意：只能下载【书画】和【拾英】板块免费的，需要会员的不能下载，单线程下载，有点慢。
希望大佬优化一下代码吧。

大佬，请问一下执行这个文件后就能自动合并下载吗？下载会保存在哪个位置。
保存在脚本目录，自动合并，是先下载到内存，再合并，可能所需时间有点长，你可以把64-65行取消注释，就把所有的分片下载到本地了 感谢分享，点了 谢谢分享，刚好学习一下。 谢谢分享 楼主辛苦 学习一下 刚需，感谢分享 谢谢分享，刚好学习一下 多谢分享 学习一下
