枕套

使用 Python 批量处理图像：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（包装器）。许可条件：GNU 通用公共许可证 v3 或更高版本 (GPLv3+) 对于 Gui 选项 checkout 分支 'gui'

要求

python >= 3.5，枕头

安装

最简单的选择是使用 sudo 安装 pip。

sudo python3 -m pip install pillowcover --upgrade

--OR-- 以没有 sudo 的用户身份安装。这会将其安装在 ~/.local/bin/ 中，确保此路径在您的 $PATH 中。

python3 -m pip install --user pillowcover --upgrade

如果未找到，请将以下内容添加到您的 .bashrc 或 .zshrc

# Add to PATH to Install and run programs with "pip install --user"
export PATH=$PATH:~/.local/bin

用法

将亮度、对比度、锐度提高 20% 并将所有图像（横向、纵向）的大小调整为 1920 像素的最大尺寸（使用最大尺寸。高度或宽度）并在给定文件夹中将它们压缩到 60%，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（从左上角 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

  -s SHARPNESS, --sharpness SHARPNESS
                        Change sharpness level, 1.00 is the current value
  -r RESIZE, --resize RESIZE
                        Resize img, keep ratio. provide the maximum
                        length/width value as one number. e.g pillowcase.py
                        img -r 1920
  -R RESIZE_RATIO, --resize-ratio RESIZE_RATIO
                        Resize img by providing new width and length e.g
                        pillowcase.py img -R "640 480"
  -k CROP, --crop CROP  Crop img by providing starting point then width and
                        length from it e.g pillowcase.py img -k "0,0,640,480"
  -q COMPRESSION, --compression-quality COMPRESSION
                        Compression quality 1-100, 100 means no compression at
                        all
  -x EXTENSION, --extension EXTENSION
                        Specifiy the output extension. Can be 'jpg', 'jpeg',
