pillowcover-gui的Python项目详细描述
枕套
使用python对图像进行大规模操作：更改亮度、对比度、清晰度、调整大小、压缩、裁剪和转换（例如png到jpg）。 使用枕头的简单脚本（包装纸）。 许可使用：GNU通用公共许可v3或更高版本（GPLv3+）

如果找不到，请将以下内容添加到.bashrc或.zshrc中
# Add to PATH to Install and run programs with "pip install --user"exportPATH=$PATH:~/.local/bin
用法
将亮度、对比度和清晰度提高20%，并调整所有图像（横向、纵向）的大小 最大尺寸为1920像素（使用最大尺寸。高或宽）并压缩到60% 在给定的文件夹中，同时保持相同的纵横比。
pillowcover -d /home/user/Pictures/ -b 1.20 -c 1.20 -s 1.20 -r 1920 -q 60
裁剪（左角640*480）和转换（从PNG到JPG）文件夹中的所有图像。
plc -d /home/user/Pictures/ -k "0,0,640,480" -x jpg
