python-xmp-toolkit工具安装

#python-xmp-toolkit#xmp

0.内容概览

1.Exempi工具安装

1.1 源码获取

1.2 依赖库获取

# 1.进入第三方库expat路径
>> cd exempi/third-party/expat
# 2.将下载的expat源码放入当前路径，并对源码解压缩
>> tar -xf expat-2.6.4.tar.xz
# 3.移动解压文件到根目录
>> cd expat-2.6.4 && mv * ../
# 4.删除无用文件及目录
>> cd .. && rm -r expat-2.6.4 && rm expat-2.6.4.tar.xz

1.3 编译安装

>> cd exempi && ./autogen.sh && ./configure
>> make -j 8 && sudo make install

2.python-xmp-toolkit工具安装

2.1 直接pip安装

>> pip install python-xmp-toolkit

2.2 源码安装

>> git clone git@github.com:python-xmp-toolkit/python-xmp-toolkit.git
>> cd python-xmp-toolkit && python setup.py install

3.python-xmp-toolkit工具使用

3.1 简单获取xmp信息

from libxmp import XMPFiles, consts

# 1.打开图片
xmpfile = XMPFiles(file_path="DJI_0161.JPG", open_forupdate=True)

# 2.获取xmp信息
xmp = xmpfile.get_xmp()

# 3.打印xmp信息
print(xmp.serialize_to_str())

# 4.关闭xmpfile
xmpfile.close_file()
