茶飘香，酒罢去，聚朋友，再回楼。 Your story may not have such a happy beginning, but that doesn’t make who you are. It’s the rest of your story,who you choose to be. 为天地立心，为生民立命，为往圣继绝学，为万世开太平。 你不是父母续集，子女的前传，朋友的番外。你不妨大胆点生活，不要因为没有掌声而丢掉梦想，不要因为看不清前路而轻易放弃。我相信你生来就是高山，而非溪流。亲爱的，勇敢而热烈的活着吧。

2023新春快乐！ 旧岁千般皆如意，新年万事定称心！

SkiaSharp 初探有个 .Net Framework 4.x 的项目需要升级到 .Net 6，升级过后发现 System.Drawing.dll 库相关功能模块会报错： Could not load file or assembly ‘System.Drawing.Common, Version=7.0.0.0, Culture=neutral,PublicKeyToken=cc7b13ffcd2ddd51’.系统找不到指定文件。 因为 System.Drawing 对跨平台不支持，只支持Windows系统，.Net 6 貌似不再支持。 于是使用 SkiaSharp 代替。 123456789101112131415161718192021222324252627282930313233343536373839404142434445464748495051525354555657585960616263646566676869707172737475767778798081828384858687888990919293949596979899 ...
