pillow压缩gif图片

pillow10.1.0 + python3.10

python

from PIL import Image


def compress_gif(input_path, output_path):
    # 打开原始GIF文件
    image = Image.open(input_path)
    print(image.n_frames)
    # 将每一帧保存为单独的图片
    frames = []
    for frame in range(0, image.n_frames):
        image.seek(frame)

        # 创建新的Image对象并设置相同大小、模式等属性
        new_frame = Image.new("RGBA", image.size)
        new_frame.paste(image, (0, 0))

        # 添加到帧列表中
        frames.append(new_frame)

    # 重新构造GIF动画
    compressed_gif = Image.new('RGBA', image.size)
    compressed_gif.save(output_path, save_all=True, append_images=frames, loop=0)


# 调用函数进行压缩
compress_gif("y.gif", "x.gif")

效果：

bash

# before
y.gif   12426kb

# after
x.gif   6166kb

需要下载这个模块，官网：https://cairosvg.org/

bash

pip install cairosvg

demo：

python

from cairosvg import svg2png

svg_flie_str = open('./xx.svg', 'r').read()
svg2png(bytestring=svg_flie_str,write_to='output.png')

但大概率执行失败：

bash

OSError: no library called "cairo-2" was found
no library called "cairo" was found
no library called "libcairo-2" was found
cannot load library 'libcairo.so.2': error 0x7e.  Additionally, ctypes.util.find_library() did not manage to locate a library called 'libcairo.so.2'
cannot load library 'libcairo.2.dylib': error 0x7e.  Additionally, ctypes.util.find_library() did not manage to locate a library called 'libcairo.2.dylib'
cannot load library 'libcairo-2.dll': error 0x7e.  Additionally, ctypes.util.find_library() did not manage to locate a library called 'libcairo-2.dll'

解决办法就是从这个地址：https://github.com/tschoonj/GTK-for-Windows-Runtime-Environment-Installer/releases下载：

安装到本地之后，直接双击安装，一个配置都不动的一路下一步。

完事之后，重启你的vscode或者pycharm软件，重新尝试，再报错就重启电脑。 ��
