go-mosaic

Go Report Card

go-mosaic是一个制作相片马赛克的工具。相片馬賽克,或稱蒙太奇照片、蒙太奇拼貼,是一種影像處理的藝術技巧,利用這個方式做出來的圖片,近看時是由許多張小照片合在一起的,但遠看時,每張照片透過光影和色彩的微調,組成了一張大圖的基本像素,就叫做相片馬賽克技巧

特性

  • 专为海量图片设计,可支持数百万张图片
  • 内建缓存数据库,图片删除、更改自动从缓存剔除
  • 多核构建,加载、计算、替换均为并发

使用

  • 克隆项目,编译,或者下载release
  • 执行命令,等待完成
go-mosaic.exe -src input.png -target output.jpg -lib ./test
  • 其中./test为图片文件夹,用来组成最终图片的元素。input.png为目标图片,用来生成最终的大图output.jpg。素材图片越多,生成越精确
  • 更多参数,参考help
